1. Introduction
The Roads and Maritime Services (RMS) is preparing a Review of Environmental Factors (REF) as part of the Great Western Highway upgrade at Forty Bends. The REF comprises the environmental assessment under Part 5 of the NSW Environmental Planning and Assessment Act 1979 (EP&A Act) and addresses the environmental impacts of the proposal. This report specifically addresses the likely traffic and transport impacts of the proposal.
1.1. Proposal description
The proposal forms part of a series of ongoing upgrades of the Great Western Highway. The Great Western Highway is the main road link between Sydney and Lithgow and beyond to the Central West of New South Wales. The Great Western Highway serves as:
A key freight route between Sydney and the central west of NSW, including the timber insustry in the Oberon area.
A tourist route with destinations including the Blue Mountains, historic Hartley, Jenolan Caves, Mudgee and Bathurst.
A connection between the many towns and villages along its length. Key features of the proposal are:
The proposal has been developed based on the concept design that has been prepared using the available information and current design standards and criteria for the Great Western Highway upgrade program. Some elements of the design may be further refined during detailed design. The key elements of the Construction of a new road alignment consisting of generally three lanes with two lanes eastbound to the east of Whites Creek and two lanes westbound to the west of Whites Creek. Lane widths would be 3.5 metres with shoulder widths typically varying between 1.0 metres and 2.5 metres. The upgrade alignment would diverge up to 40 metres south of the existing Great Western Highway in the vicinity of Whites Creek.
The design speed for the alignment would be 100 kilometres per hour east of McKanes Falls Road and 80 kilometres per hour west of McKanes Falls Road. The posted speed limit for the whole of the new highway alignment would be 80 kilometres per hour.
Widening of the existing alignment predominantly to the south of the Great Western Highway. The total proposal footprint of the widening works would vary from about 40 metres to 90 metres.
A central median along the length of the proposal of varying widths, ranging up to 9.5 metres. Carriageways would be separated by a combination of vegetated, depressed and paved medians.
TR-0695-C.doc Page 1 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Construction of new twin, five-span bridges, about 150 metres in length across Whites Creek. The new bridges would comprise four lanes, each 3.5 metres in width, with two lanes carrying traffic in each direction. The total width of the two bridges would be about 30 metres. Shoulders on the bridges would be between 2.5 and 3.25 metres (off-side) and 1.0 metres on the near side.
Rehabilitation works along the existing alignment of Whites Creek following the removal of the redundant section of the existing Highway. This would include creating a rehabilitated, natural creek bed in this location linking the existing alignment of Whites Creek prior to passing under the new Whites Creek bridge.
Upgrades to four existing local road intersections, including two intersections with Forty Bends Road, Daintree Close and McKanes Falls Road, to provide connection to the upgraded highway and property access points. Upgrades would include minor widening and u-turn facilities located along the western end of Forty Bends Road and about 150 metres south of the intersection of the Great Western Highway and McKanes Falls Road.
New or improved access from the existing highway to nine properties along the length of the proposal. The proposal includes provision of new or reconstructed driveways to retain existing property access.
Closure and relocation of two intersections of Forty Bends Road with the Great Western Highway. These include:
Closure of the existing intersection at the eastern end of Forty Bends Road to general traffic (except for emergency vehicles) and a new cul-de-sac constructed on Forty Bends Road.
Relocation of the existing intersection at the western end of Forty Bends Road to a point about 200 metres west of the existing intersection.
Five major cuts 14 metres to 19 metres in height located on the northern side of the proposed alignment.
Five major fill embankments 10 metres to 15 metres in height located predominantly on the southern side of the proposed alignment.
Three retaining walls would be required at the following locations
Retaining wall 1 – between approximate chainages 32080 and 32190 (about 110 metres long and up to 7.0 metres high).
Retaining wall 2 – between approximate chainage 32560 and 32725 (about 165 metres long and up to 5.6 metres high).
Retaining wall 3 – between approximate chainage 33040 and 33240 (about 200 metres long and up to 7.0 metres high).
TR-0695-C.doc Page 2 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Removal of about 300 metres of redundant Great Western Highway pavement from about 100 metres east of Whites Creek to about 200 metres west of Whites Creek, and associated culvert. This would include rehabilitation works to link this area to the existing alignment of Whites Creek.
Construction of three temporary and five permanent construction basins in addition to temporary access tracks along the length of the proposal.
Construction of nine new culverts along the length of the proposal to manage cross- drainage flows and six new culverts across access roads and service roads as part of the proposal. One existing culvert would be retained at the western end of the proposal. A total of 23 existing drainage culverts under the Great western Highway would be either decommissioned or removed.
Measures to mitigate the formation of black ice, including the relocation of the road alignment to the south away from the Hassans Walls escarpment in key locations and an active maintenance program.
A main compound site located east of the western end of Forty Bends Road, in addition to smaller stockpile areas along the length of the proposal during construction.
A combination of wildlife crossing structures, which would include three fauna underpasses (box culverts), canopy rope bridges at Whites Creek and the western underpass and glider poles located at Whites Creek and near the western fauna underpass.
Relocation of the existing intersection at the western end of Forty Bends Road to a point about 200 metres west of the existing intersection. An overview of the proposal is presented on Figure 1-1.
1.2. Proposal objectives
The overall proposal objectives for the Great Western Highway upgrade between Mount Victoria and Lithgow (including the Forty Bends upgrade) are to:
Improve road safety.
Improve freight efficiency.
Cater for the mix of local, through and tourist traffic.
Be sensitive to the area’s natural environment, heritage and local communities. The proposed upgrade is currently at the concept design stage. The concept design represents the refinement of the preferred route alignment and integrates road safety benefits with local area improvements such as reduced conflict points and the separation of local and through traffic.
In this context, a conflict point is the point at which a road user crossing, merging with, or diverging from a road or driveway conflicts with another road user utilising the same road or driveway.
TR-0695-C.doc Page 3 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
The peak year of construction is anticipated to occur in 2013. The assumed year of opening for the Forty Bends upgrade is 2015. The future design years for traffic volume reporting purposes are 2025 and 2035.
1.3. Scope of this report
The following scope of works has been completed in preparing this report:
A review of existing conditions within Forty Bends including the road network, road performance, intersection layouts, road safety concerns, public transport amenity, pedestrian and cyclist facilities and residential access.
A review of future conditions within Forty Bends without the Great Western Highway being upgraded.
A review of future conditions within Forty Bends when the Great Western Highway has been upgraded including the changes and improvements to the road network, road performance, intersection layouts, road safety concerns, public transport amenity, pedestrian and cyclist facilities and residential access.
Assessment of the likely impacts of construction traffic and construction works during the upgrade, the impacts to the local community and residential access.
A review of the proposal’s road safety objectives and the necessary mitigation measures and strategies to improve road safety and to reduce or minimise impacts.
1.4. Methodology
Traffic volumes stated in this report have been referenced from the Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance, Concept Design Traffic and Transport Report (April 2012), where a review of all previous traffic volume surveys undertaken had been compiled.
Traffic volumes stated for intersection modelling and mid-block capacity analysis purposes were applied from traffic surveys undertaken in May 2011.
Future linear traffic growth rates for both light and heavy vehicles have been sourced from the Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance, Concept Design Traffic and Transport Report (April 2012).
1.5. Proposal study area
The Forty Bends proposal study area is shown in Figure 1-1 on the following page. The study area as described throughout this report is defined by the Great Western Highway west of McKanes Falls Road to east of Forty Bends Road and the side roads including McKanes Falls Road, Daintree Close, Forty Bends Road. In addition, the study area contains service roads, fire trails and property accesses off the Great Western Highway.

2. Existing condition assessment
2.1. Road network
The road network in the study area is shown in Figure 2-1 with descriptions of the roads as below.
2.1.1. Great Western Highway
The Great Western Highway is a classified road that starts at Broadway in the city of Sydney (also referred to as Parramatta Road) and continues west through Parramatta to Emu Plains. The Great Western Highway connects to the western end of the M4 Motorway at Emu Plains where it continues further west towards Bathurst.
The Great Western Highway has a posted speed limit of 80 kilometres per hour within the study area.
The existing Great Western Highway alignment contains a number of reverse and broken back curves. The grade of the highway is undulating over this section with maximum grades of up to 7.5 per cent. Shoulder widths are inconsistent across this section.
There are points of direct private access generating slow moving turning traffic which conflicts with the through highway traffic.
The existing road alignment has a limited number of opportunities for passing other vehicles.

2.1.2. Forty Bends Road
Forty Bends Road is a local narrow two-way undivided road that provides access to local residential properties. Sections of the road have steep gradients of up to 14 per cent and there are several tight curves. It connects to the Great Western Highway in two locations. The most prominent connection is at the western end, while the eastern connection is not obvious from the highway. No posted speed limit signs are located on Forty Bends Road and therefore a default speed limit of 50 km/h would apply (local road low speed environment).
2.1.3. Daintree Close
Daintree Close is a local narrow unmarked two-way undivided road that provides access to local residential properties from the Great Western Highway via Forty Bends Road. Daintree Close intersects with Forty Bends Road just south of its intersection with the Great Western Highway. No speed limit signs are located on Daintree Close and therefore a default speed limit of 50 km/h would apply (local road low speed environment).
2.1.4. McKanes Falls Road
McKanes Falls Road is a local two-lane two-way undivided road with no shoulders. It has a five tonne load limit and a posted speed limit of 80 km/h. It connects the Great Western Highway at the western end of the Forty Bends section and Jenolan Caves Road approximately seven kilometres to the south.
2.2. Traffic volumes and vehicle composition
Traffic volumes for the Great Western Highway and those local roads that intersect with it including McKanes Falls Road and Forty Bends Road are shown in Table 2-1. The proportion of through traffic is approximately 95 per cent with local traffic making up the remaining five per cent of the traffic. Automatic tube counts were taken over a two week period between 7 and 21 May 2011. The peak hour in Table 2-1 is the highest volume of traffic in a one hour period in the morning (AM) and in the afternoon (PM). The peak hour volumes indicate the AM peak occurs between 7:45 am and 8:45 am and the PM peak between 3:30 pm and 4:30 pm.
TR-0695-C.doc Page 9 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Table 2.2-1: Existing (2011) traffic volumes and composition
Road Daily Heavy Peak hour traffic Vehicle% (vehicles per hour) (vehicles AM PM per day) Great Western Highway Eastbound 3950 220 350 14.7% Westbound 3950 260 300 McKanes Falls Road Northbound 185 16 9 5.1% Southbound 185 6 21 Forty Bends Road Northbound 50 4 2 - Southbound 50 2 6
Traffic in this section is generally evenly split (50 per cent in either direction) over the duration of a day. This is especially the case on local roads where local residents would have a daily return trip split.
2.3. Road network performance
The Roads and Traffic Authority Guide to Traffic Generating Developments (2002) sets out two- way hourly road capacities for two-lane roads for different levels of service, with a design speed of 100 km/h, as shown in Table 2-2. Although the posted speed limits on the Great Western Highway is 80 km/h within the study area, Table 2-2 provides guidance in determining the mid- block Level of Service (LoS) based on the peak hour flow in both directions, and the proportion of heavy vehicles.
The amount of congestion is related to the volume of traffic, the characteristics of the road and the composition of the traffic stream. The mid-block LoS is a qualitative measure used to describe the potential for delay during traffic operation, usually in peak demand situations. Mid- block LoS is designated by assigning the letters A to F, with LoS A representing the best and F the worst. LoS ratings of E and F are commonly considered unacceptable. The LoS are described in the Guide to Traffic Management Part 3 Traffic Studies and Analysis, (Austroads, 2009) as follows:
LoS A is a condition of free flow in which individual drivers are virtually unaffected by the presence of others in the traffic stream. Freedom to select desired speeds and to manoeuvre within the traffic stream is extremely high, and the general level of comfort and convenience provided is excellent.
LoS B is in the zone of stable flow and drivers still have reasonable freedom to select their desired speed and to manoeuvre within the traffic stream, although the general level of comfort and convenience is a little less than with LoS A.
TR-0695-C.doc Page 10 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
LoS C is also in the zone of stable flow, but most drivers are restricted to some extent in their freedom to select their desired speed and to manoeuvre within the traffic stream. The general level of comfort and convenience declines noticeably at this level.
LoS D is close to the limit of stable flow and is approaching unstable flow. All drivers are severely restricted in their freedom to select their desired speed and to manoeuvre within the traffic stream. The general level of comfort and convenience is poor, and small increases in traffic flow will generally cause operational problems.
LoS E occurs when traffic volumes are at or close to capacity, and there is virtually no freedom to select desired speeds or to manoeuvre within the traffic stream. Flow is unstable and minor disturbances within the traffic stream will cause break-down.
LoS F is in the zone of forced flow. The amount of traffic approaching the point under consideration exceeds that which can pass it. Flow break-down occurs, and queuing and delays result.
Table 2-2: Level of Service (LoS) and threshold peak hour flow on two-lane rural road in 100 km/h zone
Terrain Level of Threshold peak hour flow (veh/hr) Service 0% heavy 5% heavy 10% heavy 15% heavy vehicles vehicles vehicles vehicles Level B 630 590 560 530 C 1030 970 920 870 D 1630 1550 1480 1410 E 2630 2500 2390 2290
Source: RTA Guide Traffic Generating Developments (2002) Level of Service (LoS) A applies to peak hour flows less than the LoS B threshold flows
The capacity of a single lane with uninterrupted flow is calculated by using the following equation:
C = 1800 fW fHV
C = 1800*0.80*0.69 = approximately 1,000 vehicles per hour per lane
Where:
C = capacity in vehicles per hour under prevailing roadway and traffic conditions
FW = adjustment factor for narrow lanes and lateral clearances
FHV = adjustment factor for heavy vehicles
FHV = 1/[1+PHV (EHV -1)]
FHV = 1/[1+0.147 (4 -1)] = 0.69
TR-0695-C.doc Page 11 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
PHV = the proportion of heavy vehicles in the traffic stream, expressed as a decimal
EHV = the average passenger car equivalents for heavy vehicles
(Source: Austroads Guide to Traffic Management Part 3: Traffic Studies and Analysis)
Based on the information gathered from the traffic surveys, the existing road network mid-block performance is shown in Table 2-3.
Table 2-3: Existing (2011) peak hour flow on two-lane rural road (veh/hr)
Road Section No of Period Volume Capacity Heavy LoS V/C Lanes (veh/hr) (veh/hr) vehicle ratio (%) Great Western 2 AM peak 480 20001 14.7% A 0.24 Highway between 1 McKanes Falls PM peak 650 2000 14.7% B 0.33 Road and at the eastern end of Forty Bends Road McKanes Falls 2 AM peak 20 20001 5.2% A 0.01 Road south of the 1 Great Western PM peak 30 2000 5.2% A 0.02 Highway
Note 1 – this is the capacity for two lanes
The existing peak hour flows show that the Great Western Highway within the Forty Bends section operates at a good Level of Service (LoS A for AM peak and LoS B for PM peak) under existing (2011) conditions. McKanes Falls Road operates at a good Level of Service (LoS A in both the AM and PM peak). Given the minimal traffic volumes on Forty Bends Road, which are lower than those on McKanes Falls Road, Forty Bends Road would operate at good Level of Service (LoS A in both the AM and PM peak).
2.4. Intersection layouts
Three priority sign controlled intersections currently exist on the Great Western Highway at McKanes Falls Road and either end of Forty Bends Road. Table 2-4 describes the intersections on the highway in the study area.

2.4.2. Great Western Highway and Forty Bends Road – western connection
This intersection consists of a channelised right turn (Type CHR) intersection with a right turn deceleration turn lane (refer to Figure 2-3). No acceleration lanes are provided.
The intersection of Forty Bends Road and Daintree Close is approximately 15 metres south of this intersection. This intersection is currently unmarked with little indication to vehicle priority.
Figure 2-3: Great Western Highway and Forty Bends Road Intersection – western connection
2.4.3. Great Western Highway and Forty Bends Road – eastern connection
This intersection consists of a basic T intersection (refer to Figure 2-4). Forty Bends Road is unsealed at the intersection with no formalised linemarking or delineation. Forty Bends Road at this location is primarily utilised by local residents for access to and from the Great Western Highway and acts more like a driveway with no formalised turning facilities. This intersection has no movement restrictions. Primary use of this intersection is left-in left-out. The Great Western Highway at this intersection has one lane northbound and two lanes southbound with sealed shoulders varying in width between one to two metres.

2.5. Intersection performance
2.5.1. Intersection performance parameters
The ability of the key intersection to cater for future traffic forecasts was investigated using the SIDRA intersection software package. This package provides several useful indicators in order to determine the level of intersection performance. This report has used four typical performance parameters as listed and described below:
Level of service (LoS)
Degree of saturation (DoS)
Average intersection delay
Queue length.
TR-0695-C.doc Page 15 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Level of Service (LoS) LoS is a basic performance parameter used to describe the operation of an intersection. Levels of Service range from A (indicating good intersection operation) to F (indicating over saturated conditions with long delays and queues). At signalised intersections, the LoS criteria are related to average intersection delay (seconds per vehicle). At priority controlled (give-way and stop controlled) and roundabout intersections, the LoS is based on the modelled delay (seconds per vehicle) for the most delayed movement (refer to Table 2-5).
Table 2-5: RMS Levels of Service
Level of service Average delay Traffic signals, Priority Intersection (seconds per Roundabout (‘Stop’ and ‘Give Way’) vehicle) A Less than 14 Good operation Good operation B 15 to 28 Good with acceptable delays Acceptable delays and spare and spare capacity capacity C 29 to 42 Satisfactory Satisfactory, but accident study required D 43 to 56 Operating near capacity Near capacity and accident study required E 57 to 70 At capacity. At signals, At capacity, requires other incidents will cause excessive control mode delays. Roundabouts require other control mode F Greater than 71 Unsatisfactory with excessive Unsatisfactory with excessive queuing queuing; requires other control mode
Source: RTA Guide to Traffic Generating Developments (2002)
Degree of saturation (DoS) DoS is the ratio of demand flow to capacity, and therefore has no unit. As it approaches 1.0, extensive queues and delays could be expected. For a satisfactory situation, DoS should be less than the nominated practical degree of saturation, usually 0.9. The intersection DoS is based on the movement with the highest value.
Average delay Delay is the difference between interrupted and uninterrupted travel times through the intersection and is measured in seconds per vehicle. At signalised intersections and roundabouts, the average intersection delay is usually reported. At priority controlled intersections, the average delay for the most delayed movement is usually reported.
TR-0695-C.doc Page 16 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Queue length Queue length is directly related to the number of vehicles waiting at the yield or stop line and is usually quoted as the 95th percentile back of queue, which is the value below which 95 per cent of all observed queue lengths fall. It is measured as the length occupied by the vehicles per traffic lane in metres at the start of the green period, when traffic starts moving again after a red signal. The intersection queue length is taken from the movement with the longest queue length.
2.5.2. Intersection performance
Intersection performance analysed in SIDRA based on the performance parameters discussed in section 2.5.1 is shown in Table 2-6.
Table 2-6: 2011 Intersection performance
Intersection AM peak PM peak DoS Average LoS Max 95th DoS Average LoS Max 95th delay (s) percentile delay (s) percentile queue (m) queue (m) Great Western Highway and 0.15 181 B1 1 0.21 201 B1 1 McKanes Falls Road Great Western Highway and Forty 0.13 19# B1 1 0.21 201 B1 1 Bends Road (western connection) Great Western Highway and Forty 0.15 10 A - 0.18 11 A - Bends Road (eastern connection)
Note 1 - the right turn movement at this intersection is a staged movement. The average delay encountered at the yield line and for the merge have been added together to get the overall average delay for this movement.
The main intersections currently operate with acceptable delays. As these intersections are priority controlled, the average delays are based on the approach with the longest delay. This is the right turn movement from the side road onto the Great Western Highway for the two main intersections. However, the current demand and queuing from the right turn movement does not affect the operation of the other approaches.
Given the low traffic volumes on the Great Western Highway (approximately 480 vehicles in both directions during the AM peak hour and 650 vehicles in the PM peak hour) and the low volumes on the side intersecting roads of McKanes Falls Road (approximately 25 vehicles in both directions during both the AM and PM peak hour) and Forty Bends Road (approximately five vehicles in both directions during both the AM and PM peak hour), both these intersections operate at a good LoS within capacity under existing (2011) conditions and therefore intersection performance is not considered an issue.
TR-0695-C.doc Page 17 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
2.6. Local resident access
Direct access off the Great Western Highway is provided for properties that front the Great Western Highway. Access to local side roads is provided by the key intersections of McKanes Falls Road and Forty Bends Road including the connection to Daintree Close. Refer to Figure 2-1 which shows the road network in the study area.
2.7. Land uses
Land uses within the project corridor include a combination of conservation use, rural uses, including grazing, horticulture and rural residential and transport uses.
Nearby townships and urban areas include Hartley to the east and South Bowenfels to the west. The town of Lithgow is located approximately five kilometres west and north of the proposal. It contains more diverse land uses, including urban development, services and community facilities to support the surrounding rural areas.
2.7.1. Residential land
Residential uses within the study area are located along the Great Western Highway and McKanes Falls Road and generally comprise dwellings on rural properties or low-density rural residential development. In particular, a number of rural residential properties are located at Daintree Close on the southern side of the Great Western Highway.
Areas of urban residential development are also located near to the study area at South Bowenfels and Lithgow.
2.7.2. Commercial and industrial land
There is a limited number of commercial land uses located within the study area, with these generally comprising agri-businesses and an art gallery located at Daintree Close.
East of the study area, a number of small businesses are located adjacent to the Great Western Highway at Little Hartley and Hartley including cafes, short-term accommodation and specialty shops.
2.7.3. Infrastructure and utilities
Existing infrastructure and utilities are limited within the study area and generally comprise overhead and underground transmission lines (administered by Telstra and Optus), fibre optic cable (administered by Telstra) and water utilities running parallel to the existing highway.
Classified roads maintained by the RMS within and adjacent to the study area include the Great Western Highway, Bells Line of Road, and Darling Causeway. Other public roads are maintained by Lithgow City Council.
TR-0695-C.doc Page 18 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
2.7.4. Environmental protection
An area identified for environmental protection is located north of the Great Western Highway. This includes Hassans Walls Reserve and lookout. The Hassans Walls Lookout is located approximately 1100 metres above sea level and is the highest lookout in the Blue Mountains. The lookout provides views over Mount Wilson, Mount York, Mount Tarana and Mount Blaxland as well as the whole of the Hartley Valley.
2.7.5. Agricultural land
Agricultural land uses within the study area generally comprise grazing and horticulture uses, including orchards (fruit trees).
Agriculture is an important industry in the Lithgow local government area. At a regional level, agricultural land use covers about 29 per cent of the Lithgow local government area with the majority of this area being used for grazing (Lithgow City Council, 2011). The majority of agricultural capable land has been divided into holdings less than 400 hectares, with only 33 per cent of the land within the local government area classed as suitable for agricultural production (Lithgow City Council, 2011).
Land uses in the proposal corridor are shown in Figure 2-5.

2.8. Pedestrian and cycle access
Pedestrian or cyclist facilities are not provided within the proposal site, or the adjoining side roads including McKanes Falls Road, Daintree Close and Forty Bends Road.
Currently, pedestrian and bicycle movements along and across the Great Western Highway outside of Mount Victoria are restricted by a lack of formal facilities. There are no dedicated bicycle and pedestrian paths, with narrow shoulders restricting the use of the highway by cyclists. With future subdivisions proposed in the area, it is likely that the amount of non- vehicular traffic would increase.
2.8.1. Strategic Planning for cyclists and pedestrians
The Blue Mountains Bike Plan 2020 (Blue Mountains City Council, 2007) highlighted a number of potential bicycle routes through the Blue Mountains area. It indicated the potential need for a cycleway system connecting the Blue Mountains to Lithgow, the Hawkesbury, Penrith and Sydney, maximising connectivity to neighbouring regions. One key route highlighted that will have some impact on the study area is the Mount Victoria to Hartley (Lithgow LGA) – Off-road cycle route. Although travelling through the study area for this proposal, this cycle route would be located off-road and therefore would not impact on the existing or future Great Western Highway operation.
The Metropolitan Greenspace Program (MGP), as part of the Metropolitan Plan for Sydney 2036 (NSW Government, 2010), identified the Upper Blue Mountains trail as being significantly important to the local and regional cycling and walking networks. In 2010, funding was granted to Blue Mountains City Council to commence planning and detailed design work for a section of the Great Blue Mountains Trail, the Wentworth Falls to Mount Victoria trail (approximately 17 kilometres in length), with links to the Lithgow and Oberon trail networks. Potential links to the trail network could occur from the northern side of the study area.
2.9. Public transport services
2.9.1. Local bus services
There are no regular public bus services available to connect Mount Victoria and Lithgow. The Jones Bros Bus Company, a private bus company is based in Lithgow. However, it does not operate any scheduled services in the study area.
Local residents rely on private vehicles for transport within and beyond the study area. Despite this, a number of buses do travel through the study area, as discussed in sections 2.9.2 to 2.9.4 below.
There are no formal bus stops within the study area.
TR-0695-C.doc Page 21 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
2.9.2. Regular regional bus routes
Greyhound coaches travel through the study area enroute between Sydney/Katoomba and Lismore/Orange. There are no stops within the study area.
2.9.3. School buses
Jones Bros Bus Company operates eight school bus routes which utilise the Great Western Highway between Mount Victoria and Lithgow. Some of these operate as express services between Mount Victoria and Lithgow, while others pick up and set down along the highway and on side roads.
School bus routes are dynamic in nature and tend to alter from year to year in response to student demand. Currently a mixture of local services and express services between Lithgow and Mount Victoria/Blackheath/Katoomba are in operation.
Buses generally stop at formal stops along their route (outside the study area), and also pick up and set down passengers at informal gathering points which may include locations within the study area. Many students are collected from the driveway of private properties along the highway.
While buses do not currently use McKanes Falls Road, it may be utilised in the future if demand requires.
2.9.4. Tour buses
Numerous tour buses operate daily, mainly from Sydney and Katoomba to the Blue Mountains and Jenolan Caves. Some operators travel to and from Lithgow as part of their tour and therefore would pass through the study area.
2.10. Vehicle rest areas
There are no heavy vehicle rest areas within the study area.
The closest heavy vehicle rest area to the study area is located at River Lett Hill, about 1.1 kilometres east of the eastern connection of Forty Bends Road. This rest area provides approximately six westbound parking spaces and three eastbound parking spaces.
There are no rest areas within the study area. There are rest areas outside the study area, however these would not be changed as part of the construction works.
2.11. Emergency services access
There are informal access points to fire trails on the northern side of the existing alignment. Emergency service access including fire trails is shown in Figure 2-1.
TR-0695-C.doc Page 22 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
2.12. Historical crash data
Crash data between January 2004 and December 2010 recorded 23 crashes, of which two were fatal crashes and 12 were injury crashes. The location of the crashes indicates that there is a string of crashes east of Forty Bends Road (western intersection with Great Western Highway) as shown in Figure 2-6 below. Out of the 23 crashes; 57 per cent of the crashes were the result of vehicles leaving the carriageway on a curve or while turning; 17 per cent of the crashes were the result of vehicles leaving the carriageway on the straight; 17 per cent of the crashes were the result of vehicles travelling in the opposing directions; and nine per cent of the crashes were the result of vehicles travelling in the same direction.
The two fatalities occurred in 2004 in wet conditions, both involving heavy vehicles and within the vicinity of McKanes Falls Road and Forty Bends Road intersections. One fatality was the result of the vehicle leaving the carriageway while the other involved a head on collision.
Eighteen of the 23 crashes occurred between 2004 and 2009, of which nearly 80 per cent of the crashes occurred in conditions of poor visibility (raining, overcast or snow/ice). Crash data for 2010 did not provide the weather conditions for these crashes.
The RTA's State Plan has a target of “reducing road fatalities to 0.7 per 100 million vehicle kilometres (Mvkt) travelled by 2016”. This whole length of Great Western Highway, from Marrangaroo to Soldiers Pinch, including the Forty Bends section, has a fatality rate approximately double the target figure with 1.5 per 100 Mvkt (Source: Mount Victoria to Lithgow Great Western Highway Upgrade Strategic review of a Newnes Plateau corridor, Cardno 2008).

2.13. Road safety
A number of road safety initiatives have been implemented as part of the upgrades to the Great Western Highway between Mount Victoria and Lithgow. Within the Forty Bends section, barriers (both W-beam barriers on the edge and concrete barriers in the centre) were installed in 2004 to assist with road safety and reduce the number of vehicles leaving the carriageway.
During the winter months, mist can reduce visibility and it is not uncommon for snow to settle and close the highway for short periods. Black ice also forms at some locations when the temperature drops below freezing which leads to unsafe driving conditions when travelling at higher speeds as the road pavement becomes icy and slippery.
The formation of black ice is a key community concern and an important consideration for the proposal. Measures to address black ice are discussed in section 4.1.4.

3. Future condition assessment
As part of the future condition assessment, scenarios without upgrade (do nothing) and with the upgrade have been considered and are discussed in this section.
3.1. Without upgrade
If this proposal did not proceed in the future then the road performance of the Great Western Highway would continue to operate similar to existing conditions as discussed in section 2. Future road mid-block performance is shown in Table 3-1 to 3-3 and intersection performance shown in section 3.3.1.
Tables 3-1 to 3-3 show the forecast traffic volumes on the Great Western Highway without the upgrade for 2015, 2025 and 2035 respectively, and include both peak hourly and daily traffic volumes.

3.2. With upgrade
If this proposal was to proceed in the future then the road performance of the Great Western Highway would improve from existing conditions with increased safety. Changes to the road network and intersection layouts as part of the proposal is discussed further below.
TR-0695-C.doc Page 28 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
3.2.1. Road network
The upgrade of Forty Bends includes three lanes east of Whites Creek, with two lanes eastbound. West of Whites Creek there would be three lanes with two lanes westbound. The existing alignment would be widened predominately to the south, diverging up to 40 metres south of the existing alignment in the vicinity of Whites Creek. A new bridge would be constructed at Whites Creek, about 150 metres in length. The existing road network would be upgraded (including Forty Bends Road, Daintree Close and McKanes Falls Road) to connect to the upgraded highway and property access points. U-turn facilities would be provided on McKanes Falls Road and Forty Bends Road to enable safe local traffic movements.
Forty Bends Road changes The existing intersection at the western end of Forty Bends Road would be closed and reinstated via Daintree Close to connect to the Great Western Highway (approximately 180 metres west of the existing intersection). A U-turn facility would be incorporated on Forty Bends Road for improved access when a central median is installed on the Great Western Highway restricting turning movements to dedicated intersections. Vehicles travelling eastbound on the Great Western Highway wishing to travel in the opposite direction (westbound) would make a right turn movement into Forty Bends Road, travel to the U-turn facility, travel back on Forty Bends Road towards the Great Western Highway and then make the left turn to travel westbound.
Forty Bends Road would be truncated at the eastern end, with access to emergency vehicle only via a formalised fire trail/track to the Great Western Highway with locked gates at each end. All vehicular access to and from Forty Bends Road from the Great Western Highway would be via a new connection at the western end. A cul-de-sac would be created at the truncated end of Forty Bends Road.
U-turn facility on McKanes Falls Road U-turn facilities would be incorporated for improved access and U-turn capability. Vehicles travelling eastbound on the Great Western Highway wishing to travel in the opposite direction (westbound) would make a right turn movement into McKanes Falls Road, travel to the U-turn facility, travel back on McKanes Falls Road towards the Great Western Highway and then make the left turn to travel westbound.
Property access New or improved access from the existing highway to nine properties would be provided along the length of the proposal. The proposal includes provision of new or reconstructed driveways to retain existing property access.
TR-0695-C.doc Page 29 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
3.2.2. Traffic volumes and vehicle composition
Based on previous traffic surveys and growth predictions completed for the greater Mount Victoria to Lithgow (MV2L) project, a linear traffic growth rate of 1.7 per cent per annum has been adopted for light vehicles and 1.3 per cent per annum for heavy vehicles (Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance, Concept Design, Traffic and Transport Report April 2012). These traffic growth rates have been applied to predict future traffic volumes on the Great Western Highway in the proposed opening year (2015) and future year design horizons (2025 and 2035). Tables 3-4 to 3-6 show the forecast traffic volumes on the Great Western Highway with the upgrade for 2015, 2025 and 2035 respectively, and include both peak hourly and daily traffic volumes.
Table 3-4: 2015 forecasted traffic volumes and road performance with the upgrade
Road Daily traffic Heavy Peak hour LoS (vehicles Vehicle% (vehicles per hour) per day) AM PM AM PM Great Western Highway Eastbound 4200 230 380 14.7% A A Westbound 4200 270 320 McKanes Falls Road Northbound 190 16 9 5.2% A A Southbound 190 6 22 Forty Bends Road Northbound 50 4 2 - A A Southbound 50 2 6

The percentage of heavy vehicles on the Great Western Highway would remain unchanged to the design year due to the similar percentage of annual growth between light and heavy vehicles over the projected timeframe.
3.2.3. Road network performance
Changes to the highway cross section, carriageway width and improvements to alignment and sight distance would improve traffic flow leading to improved Level of Service. With the addition of a lane in either direction for the majority of this proposal, the Level of Service on the Great Western Highway would improve from LoS B to LoS A in the PM peak in 2015, and from a LoS B to LoS A in both the AM and PM peaks in 2025 and 2035. Although volumes on the highway would increase into the future at a predicted steady traffic growth rate, ample road capacity would remain and traffic flow performance would continue to operate well within capacity.
3.2.4. Intersection layouts
Left-in and left-out fire trail and minor property accesses along the northern side of the highway would be provided wherever an existing property access is located. The upgrades to the main intersections along the Great Western Highway and realignment of side roads connecting with the Great Western Highway are discussed further below.
TR-0695-C.doc Page 31 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Proposed Great Western Highway and Forty Bends Road Intersection Access to Forty Bends Road would be retained via a seagull intersection layout at the western end of the proposal. This intersection would permit all movements to and from the proposal. Forty Bends Road would be truncated to form a cul-de-sac at the eastern end. The intersection of the Great Western Highway and Forty Bends Road (eastern connection) would be restricted to emergency vehicle access only. Gated access would be provided between the Great Western Highway and Forty Bends Road at this location. Vehicle restrictions at this intersection would reduce the traffic volumes through this intersection, therefore reducing vehicle movements and potential conflicts, and increasing the safety of this intersection. The cul-de-sac would provide a turn-around area for local traffic to travel back to the Great Western Highway via the Forty Bends Road (western connection) intersection. Vehicle access between the cul-de-sac and the Great Western Highway would be restricted to emergency vehicle access only and therefore the need for a turn-around area would be provided in the form of a cul-de-sac at this location. A U- turning facility would also be provided on the realigned Forty Bends Road to facilitate U-turn movements. A formalised bus stop would be installed at this U-turn facility.
Figure 3-1 shows the proposed Forty Bends Road connection with the Great Western Highway and Daintree Close as well as the U-turn facility on Forty Bends Road. Figure 3-2 shows the proposed Forty Bends Road T-intersection realignment for emergency vehicle access with the Great Western Highway and the cul-de-sac at the eastern end of Forty Bends Road. Figure 3-3 shows access to McKanes Falls Road which would be retained via a seagull intersection layout allowing all movements to and from the proposal. A U-turn facility would be provided on McKanes Falls Road to facilitate U-turn movements for west bound traffic originating to the west of the intersection and for buses to turn around.
Figure 3-2 shows the proposed Forty Bends Road T-intersection realignment for emergency vehicle access with the Great Western Highway and the cul-de-sac at the eastern end of Forty Bends Road.

3.3. Intersection performance
Future condition intersection performance has been assessed with and without the upgrade.
3.3.1. Without upgrade
Intersection performance in 2015, 2025 and 2035 without the upgrade is shown in Table 3-7 to Table 3-9.

The average delay encountered at the yield line and for the merge have been added together to get the overall average delay for this movement.
The results indicate that without the upgrade, the performance of the intersections would remain relatively similar to the 2011 results (refer to Table 2-6) in 2015, 2025 and 2035, with slight increases in the average delay. These increases in delay do not change the LoS indicator.
3.3.2. With upgrade
Intersection performance in 2015, 2025 and 2035 with the upgrade is shown in Table 3-10 to Table 3-12.

The average delay is encountered at the yield line and once a vehicle has made the right turn a continuous lane is provided with no vehicle merge required.
The results indicate the upgrade would improve the LoS at the two main intersections so they both operate well in 2015, 2025 and 2035, with slight decreases in the average delay.
TR-0695-C.doc Page 39 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Changes to traffic volumes from the existing (2011) conditions to future conditions would be minimal, with forecast annual linear traffic growth rates at 1.7 per cent for light vehicles and 1.3 per cent for heavy vehicles. The intersections of McKanes Falls Road and Forty Bends Road with the Great Western Highway would be upgraded in the proposed opening year (2015), providing enhanced safety for turning movements and improved intersection capacity and performance. Given the forecasted low traffic volumes on the Great Western Highway in 2025 and 2035, (approximately 590 to 710 vehicles in both directions during the AM peak hour and 830 to 980 during the PM peak hour) and the low volumes on the side intersecting roads of McKanes Falls Road (approximately 30 vehicles in both directions during both peak periods) and Forty Bends Road (approximately five vehicles in both directions during both peak periods), both these intersections would continue to operate well within capacity under future conditions and therefore intersection performance is not considered an issue.
3.4. Access management principles
An access management review has been conducted as part of the concept design development. This review has examined provisions for mobility and access for the proposal, seeking to consolidate, optimise and improve access for all modes of transport, whilst retaining or improving the level of safety afforded to road users. A number of documents and reports (refer to Section 8 References) have been prepared previously which address traffic and transport, and road safety matters for the upgrade and the following basic access management principles and have been incorporated into the design of the Forty Bends section:
Property access on the proposal – left in/left-out favoured. Right turn out not permitted. Right turns in to property access points to be avoided if possible. Provide for school buses.
Other local roads – provision for school buses to be retained on side roads where required.
Design vehicle is a 19 metre semi-trailer (articulated vehicles). These principles have been supported by the implementation of a centre median and upgrades of the McKanes Falls Road and Forty Bends Road intersections with the Great Western Highway to seagull intersection layouts.
The design of the highway upgrades have been completed in a manner to control access, using the access management principles to derive the design layout, thus eliminating conflict points, and concentrating vehicle movements to formalised intersections, further increasing safety.
3.4.1. Pedestrian and cycle access
There would be no provision for pedestrians on the upgraded section of the Great Western Highway. The provision for cyclists would be accommodated in the 2.5 metre wide shoulders.
3.4.2. Public transport services
No changes are foreseen to public transport services. However, a formalised bus stop would be provided at the U-turn facility on McKanes Falls Road.
TR-0695-C.doc Page 40 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
3.5. Potential impacts to access
3.5.1. Local residents
The implementation of a divided carriageway along the Great Western Highway with opening for turning/crossing vehicle movements only at the intersections of McKanes Falls Road and Forty Bends Road (western connection) would lead to increased travel times for local residents living adjacent to the highway. These residents would have to travel up to about 900 metres to the nearest U-turn facility prior to making a turn in the desired direction of travel.
3.5.2. Emergency services
It is recognised that suitable access for emergency services vehicles, particularly Rural Fire Service vehicles, is required. As the development of the design progresses, consultation with relevant stakeholders would be undertaken to ensure that their requirements are met. Access to emergency vehicles is confined to median openings on the highway and would remain unchanged at the McKanes Falls Road and Forty Bends Road intersections.
3.5.3. Pedestrian and cycle access
There would be no impacts to access for both pedestrians and cyclists.
3.5.4. Public transport services
Buses would not be permitted to pull over adjacent to the highway at informal bus stops. A formalised bus stop would be created at the U-turn facility on McKanes Falls Road with passengers having to walk back to the highway to reach their property.
3.6. Future development in the local area
Future land uses near the upgrade mainly comprise proposed residential development, which is generally located in South Bowenfels, also referred to as the South Bowenfels Release Area. Recent rezoning of land in South Bowenfels to 1(d) Rural (Future urban) has allowed for about 862 potential lots on the western side of the Great Western Highway and a further 105 lots on the eastern side of the Highway. The South Bowenfels area is subject to the provisions of the South Bowenfels Development Control Plan – Residential Development (2006).
The provision of future residential land in the Lithgow local government area is generally restricted by the availability of critical infrastructure such as water and wastewater treatment, the adjacent Blue Mountains National Park and World Heritage Area, the topography, and the need to protect the Sydney Drinking Water Catchment. Existing road corridors also restrict residential development.
Previous consultation for the Great Western Upgrade project also identified a desire by the community within the local government area for the low density rural-residential character in the region to be maintained.
TR-0695-C.doc Page 41 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Whilst future residential developments are likely to occur in the vicinity of the proposal (e.g. on McKanes Falls Road), they are not expected to adversely affect the operation of the new intersection. The posted speed limit on McKanes Falls Road would remain at 80 km/h.
3.7. Future strategic transport considerations
A review of the Central West Transport Needs Study Final Report (May 2009) prepared by Sinclair Knight Merz determined that:
When future traffic volumes were applied to the existing network within the region, no capacity problems were identified.
The existing size of the network (road lanes and the number of train paths required to move traffic on the network) would be adequate for future needs for at least 25 years.
Road safety and network improvements on the Great Western Highway may be warranted to improve transport efficiency.
The costs of improving the Bathurst-Sydney rail service and the regional rail services are likely to outweigh the user benefits given the low demand to use rail. Additional or improved bus services are likely to be the least costly alternative to improved rail passenger transport services.
The viability of the Central West economy is dependent on access to ports. Access and capacity to Port Botany (up to 2021) can be maintained by extending train lengths and from the proposed Sydney rail network improvements. Beyond 2021, when Port Botany may be at capacity, growth in freight traffic could be partially diverted to Newcastle. The review of this study has been relevant to this proposal as it considers future transport needs for both road and rail infrastructure within the study area.

4. General road safety assessment
One of the key objectives for this proposal is to improve road safety. The design of the Forty Bends upgrade has adopted a controlled access approach, using the access management principles to derive the design layout, thus eliminating conflict points, and concentrating vehicle movements to formalised intersections, further increasing safety. Several road safety measures would be implemented for this proposal to improve road safety and include the following.
4.1. Managed access
The implementation of a centre median as part of the proposal would restrict right turning movements and provide for left-in left-out movements only at minor intersections and at property accesses. This would enhance safety by eliminating unnecessary risk such as overtaking manoeuvres and crossing centreline crashes and reducing the number of vehicle conflict points. This would also assist in the prevention of head on collisions, which was a result of a fatality in this location.
U-turn facilities are proposed to be provided on McKanes Falls Road and Forty Bends Road which have lower traffic volumes and a lower speed environment when compared to the Great Western Highway. These facilities would provide vehicles a safe and controlled location to turn around and travel in the opposite direction. These facilities would assist with local motorist accessing left-in left out intersections that have been restricted by the central median.
4.2. Intersection upgrades
Intersection upgrades along the Great Western Highway at McKanes Falls Road and Forty Bends Road would further improve intersection operation and safety at the intersection. The improvement in the design of the intersections by providing dedicated turning lanes and improving the road geometry on the approach would further improve safety.
The upgrade of the eastern connection of Forty Bends Road formalises this intersection. Although this intersection would be gated and is only proposed for emergency services, it would improve the safety and visibility of vehicles entering and exiting at this location.
4.3. Improved road geometry and sight distance
Improvements to the vertical and horizontal geometry and the alignment of the Great Western Highway at Forty Bends would be made leading to improved sight stopping distances (SSD) and safe intersection sight distance (SISD).
The improvement in the widths of the travel lanes and shoulders to the current standard would improve the travel along this section, and increase the safety of motorists that have stopped on the side of the road. This facility would also improve the safety for cyclists with the improvement in the shoulder width.
TR-0695-C.doc Page 43 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
The widening of shoulders would also provide an area for errant vehicles to recover, extra tracking width for heavy vehicles, space for on road cycling, room for evasive manoeuvres and a refuge for broken down vehicles.
4.4. Black ice
A number of design measures are proposed to prevent the pooling of cold air on the road surface which would help reduce the formation of black ice. The following measures would be adopted with the proposed upgrade;
Where safety barriers are required, wire rope barriers would be utilised between carriageways, together with road grading to prevent pooling of cold air.
Development of an active winter maintenance program.
Installation of a weather station to obtain local meteorological data.
Ice warning signage.
TR-0695-C.doc Page 44 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
5. Construction traffic and staging
The following section discusses construction working hours, traffic generation, access to worksites and intersection operation during construction.
5.1. Working hours and duration of work
In accordance with the Interim Construction Noise Guidelines (DECC 2009), construction works are typically restricted to the hours of:
7am and 6pm Monday to Friday.
8am to 1pm Saturday.
No work on Sundays or public holidays. However, it is possible that the construction hours for this proposal could be extended to manage local constraints such as climate and traffic. Construction activities could take place from 6am to 7pm, Monday to Friday and 7am to 4pm Saturday (the daytime period), with no work on Sundays or public holidays.
There may be certain activities that require work outside these hours, such as asphalting under traffic.
5.2. Construction workforce
The construction workforce would vary depending on the phase of construction and associated activities. The workforce would include construction and design personnel. An on-site workforce of up to 120 persons could be engaged at any given time during the construction period.
5.3. Construction staging
As the proposed upgrade is predominantly on the same alignment as the existing highway, the construction would be required to be built in stages.
It is proposed to construct the westbound carriageway whilst the traffic generally remains on the existing highway as Stage 1. Some temporary widening and temporary realignment of the existing highway would be undertaken to allow this stage to be built. The existing traffic would be reduced to two-lane two-way operation for this stage.
The bridges at Whites Creek are away from the highway and would be constructed without affecting the existing traffic configuration. The bridges would be constructed as part of the Stage 1 works.
In Stage 2, the traffic would be switched in a two-lane two-way configuration onto the new westbound carriageway to allow the eastbound upgrade to be constructed. Where the ultimate westbound carriageway is proposed to be one lane, some temporary pavement works would be required to allow the temporary two way traffic flow.
TR-0695-C.doc Page 45 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
The final stage involves opening the new westbound and eastbound carriageways in their ultimate traffic flow condition, the removal of temporary pavements and final finishing works.
5.4. Resource consumption
The proposal is a highway upgrade that involves widening an existing fill embankment and cutting into the lower slopes of Hassans Walls. Bridge and concrete works, retaining walls and drainage works are involved.
The major resource requirements for the proposal include:
Earth fill.
Quarry products including road base and drainage rock.
Construction water.
Concrete and reinforcement.
Asphalt and bitumen.
5.5. Road and lane closures
The traffic staging has been designed to ensure two-lane two-way traffic flow is always maintained.
Some short-term work under traffic control or lane closure would be required for traffic switches, barrier installation work and asphalt overlay work. No road closures or traffic diversions are anticipated during the construction period.
5.6. Construction traffic volumes
The following construction traffic volumes on the local area are anticipated. Table 5-1 shows the vehicle types and volumes expected for the proposal.
TR-0695-C.doc Page 46 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Table 5-1: Construction traffic types and volumes
Vehicle type Movements Impacted roads Duration per day Light vehicle 200 - 500 Great Western Highway, McKanes 24 Months Falls Road, Forty Bends Road Truck – external 50 - 130 Great Western Highway, McKanes 16 Months earth Falls Road, Forty Bends Road Truck – internal 50 - 130 Great Western Highway 16 Months earth Water Truck 0 - 20 Great Western Highway 16 Months Trucks – external 50 - 130 Great Western Highway 16 Months pavement Concrete Trucks 10 - 100 Great Western Highway 16 Months Delivery Trucks 0 - 10 Great Western Highway, McKanes 24 Months Falls Road, Forty Bends Road
5.7. Construction traffic volume impacts
As documented in Table 5-1 above, the proposal would create increased traffic due to construction over a 16 to 24 month period. Vehicle access to and from the site would be from the Great Western Highway, McKanes Falls Road and Forty Bends Road. Given the location of the proposal, alternative haulage and travel routes are generally not available.
The vast majority of light vehicle movements generated by construction workers would occur outside the background peak period due to the shift start and finish times (7am and 6pm respectively). The existing peak periods are between 7:45am and 8:45am in the morning and 3:30pm and 4:30pm in the afternoon. It is expected that approximately 20 to 50 light vehicle movements per hour would be generated by construction workers outside of the peak hours based on an 11 hour working day. It is assumed that 60 per cent of the light vehicle movements would originate from the west and 40 per cent from the east.
TR-0695-C.doc Page 47 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Delivery and heavy vehicle movements would occur throughout the working shift. It is expected that approximately 15 to 50 heavy vehicle movements in a peak hour based on an 11 hour working day. Based on the 2011 volumes with linear traffic growth applied to 2013, the traffic at Forty Bends would increase from 480 to 530 vehicle movements during the AM peak hour (10 per cent increase) and from 650 to 700 vehicle movements during the PM peak hour (eight per cent increase) during construction. This increase in traffic volumes due to construction vehicles is not expected to change the Level of Service on the highway, and the highway would continue to operate at LoS A in the AM peak and LoS B in the PM peak (refer to Table 2-2). It is assumed that external soil would be imported with an even split from local quarries. Trucks delivering pavement and concrete trucks are assumed to originate from the west, while the delivery trucks have been assumed to be evenly split between the west and east.
The following assumptions have been applied to the distribution of construction traffic at the McKanes Falls Road and Forty Bends Road intersections with the Great Western Highway:
20 light vehicles and 50 heavy vehicles as through traffic in either direction on the Great Western Highway.
20 light vehicles and 25 heavy vehicles turning right onto both McKanes Falls Road and Forty Bends Road and left onto the Great Western Highway (return movement).
20 light vehicles and 25 heavy vehicles turning left onto both McKanes Falls Road and Forty Bends Road and right onto the Great Western Highway (return movement). Intersection performance in 2013 with and without construction traffic at its peak is shown in Table 5-2 and Table 5-3.
Table 5-2: 2013 Intersection performance without construction traffic

Note 1 - The right turn movement at this intersection is a staged movement. The average delay encountered at the yield line and for the merge have been added together to get the overall average delay for this movement.
TR-0695-C.doc Page 48 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport

Note 1 - The right turn movement at this intersection is a staged movement. The average delay encountered at the yield line and for the merge have been added together to get the overall average delay for this movement.
The decrease in the LoS at the two main intersections is a result in the increase in the volumes of traffic turning right from the side roads. This increase is from the assumed volume of construction vehicles using the side roads to access a compound/ stockpile or to use a U-turn facility.
During construction it would be necessary to move a large amount of on-site excavated materials from cuttings to fill areas. Where practical, side-tracks would be constructed and haulage and movements would be maintained within the work area zone and separate from the travelling public. There are, however sections of the works where haulage across the proposal site would be required. Any haulage movement across or along the Great Western Highway would be in accordance with an approved traffic control plan.
Material being imported from the local quarries would use the Great Western Highway, and access the work areas from established and designated access points.
5.8. Restricted access vehicles (RAVs)
Heavy vehicle routes are designated on the RMS map of Travel Restrictions Vehicle Routes (RMS 2008). Appendix A includes maps showing the 4.6 metre high restricted vehicle routes and approved B-double routes to and from the proposal site. These are the most suitable routes for construction-related trucks.
It is expected that the majority of construction truck movements for the proposal would be tipper trucks in the form of a truck and dog trailer or semi- trailer (articulated vehicle) and therefore would have no difficulty in accessing the proposal site.
TR-0695-C.doc Page 49 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
5.9. Over-dimension vehicles
Vehicles which are overheight, oversize or overmass are subject to special operating conditions. Operators of trucking contractors would be required to apply for the necessary permits and a review of information including vehicle route maps, route assessment guidelines, travel restrictions and curfew times. The need for pilot vehicles and police escort vehicles would also need to be assessed as part of the Construction Traffic Management Plan (CTMP).
Oversize vehicles are required to deliver bridge beams and would travel via the Golden Highway, Castlereagh Highway and then on to the Great Western Highway from the Lithgow end. The oversize vehicle transporting contractor would need to apply for the necessary permits prior to delivery.
5.10. Construction compounds, stockpile sites and quarries
A number of locations have been identified as potential compounds and/or stockpile sites. The main compound site is just west of the proposed bridge over Whites Creek. This location has been identified as it is next to the major structure of the proposal and at a location central to the works, opposite the site of a large cutting and next to a large fill location. There is also access available off Forty Bends Road. Access to the compound and/or stockpile sites would be implemented at suitable locations with direct access off the Great Western Highway or via side road access where required via McKanes Falls Road or Forty Bends Road. This is to be established in locations where sight distance for entering and exiting construction vehicles is adequate.
Site compound access and temporary access requirements during construction would be designed to facilitate the largest design vehicle required for the proposal.
Suitable potential stockpile sites have been identified at each end of the proposal. Figure 5-1 shows the locations of potential compound and/or stockpile sites.
There are two quarries located in the vicinity of the proposal. These are:
Austen Quarry (Hy-Tec) - which is located approximately 20 kilometres south of the intersection of the existing highway and Jenolan Caves Road. Access to the proposed upgrade is via Jenolan Caves Road and McKanes Falls Road.
Marrangaroo (Metromix) – seven kilometres west of Lithgow. Access to the Great Western Highway is via Oakley Forest Road.

5.11. Construction access
Access points at the eastern and western tie-ins would be required to facilitate construction activities. At the site compound entry, and where construction volumes are likely to be high or where adverse geometry exists, widened shoulders would be provided. All access points and side roads would:
Have safe intersection sight distance.
Accommodate the turning movements of the largest heavy vehicle.
Provide left and right turn deceleration lanes.
Provide painted median treatments for vehicle delineation.
Provide suitable intersection layouts during the works.
5.12. Traffic management, control and signage
The proposed construction works would be programmed to minimise interaction between the construction works and the local and regional road network. This would minimise disruption to local and through traffic.
Standard traffic management measures would be employed to minimise short-term traffic impacts expected during construction. These measures would be identified in specific traffic management plans and would be developed in accordance with the RTA’s Traffic Control at Works Sites Manual (Version 4.0 June 2010).
A construction traffic management plan (CTMP) would be created for this proposal and would detail the traffic management, traffic control and road signage requirements. This is further discussed in section 6.2. The CTMP aims to remove or mitigate any proposal traffic related impacts to the road users.
5.13. Intersection performance and operation during construction
There is a channelised right turn intersection at the western end of the proposal with McKanes Falls Road and Forty Bends Road (western connection). Based on the intersection performance assessment in section 5.7, both these intersections would operate at a satisfactory Level of Service (LoS C in both the AM and PM peaks). It is considered that the traffic can be managed through the site during construction due to the reasonably low traffic volumes. This area of works would be staged so that construction at the actual intersection would be limited to the shortest possible duration.
TR-0695-C.doc Page 52 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
5.14. Impacts to local residents
There are a small number of rural properties throughout the proposal site which would be affected by the works. It is proposed to limit access to Forty Bends Road to one point at the western end which is to continue through to the final layout. Properties that have vehicular accesses from the Great Western Highway would have access maintained during construction with temporary disruption during specific activities. This would be dependent on the location of the rolling works. Traffic controllers would assist with vehicle access to and from the Great Western Highway from affected properties.
5.14.1. Local access to property
Local access to property is proposed to be maintained during construction although localised changes to access methods and locations may be implemented as necessary. These would be dealt with on an individual basis with property owners consulted prior to the works. However, short-term lane closures may be implemented during the works.
5.14.2. Detours or alternate routes
Whilst it is possible to avoid the majority of the proposal site by utilising McKanes Falls Road and Jenolan Caves Road, this route constitutes a detour of approximately 13 kilometres and is not considered a viable alternative route. Another alternative detour is via Browns Gap Road, The Gap Road and Hartley Valley Road to access Lithgow. The Great Western Highway would remain operational during construction and therefore an alternative route would not be required. Should the need for the temporary closure of the Great Western Highway be required, this would be undertaken using appropriate traffic control and management measures.
5.14.3. Increased travel times
During construction, the speed limit would be reduced to 60 km/h (40 km/h where required) through the construction works area. This would add less than one minute to the overall travel time, however, in heavy traffic this delay may be increased as there would not be opportunity to pass slow moving traffic through the upgrade area as only one travel lane may be provided at any one time.
There may be additional delays due to traffic control to allow site traffic to cross the highway. This would be monitored throughout construction to ensure traffic flow is maintained on the highway.

6. Mitigation measures and strategies during construction
6.1. Information to local residents
6.1.1. Information signage (Static, Portable VMS or Permanent VMS)
Static signage and portable variable message signs (VMS) would be positioned to provide necessary proposal information, guidance and warning to motorists that drive through, past or adjacent to the proposal area.
Permanent variable message signs (VMS) are located on the Great Western Highway at two locations within close proximity. One VMS faces westbound motorists, and is located just east of Jenolan Caves Road in Hartley and the other, facing eastbound motorists, is located just west of Main Street in Lithgow. The permanent VMS are able to provide additional proposal related information in advance of the proposal, and therefore motorists would have enough time to slow down and prepare to stop at the work sites.
6.2. Construction traffic management plan
A construction traffic management plan (CTMP) would be prepared as part of the pre- construction planning. The plan would detail how the traffic associated with the construction would be managed in accordance with the Roads and Traffic Authority 2010, Traffic Control at Work Sites, as well as relevant Australian Standards including AS1742.
The CTMP would also be used to develop site-specific traffic management measures once the construction methods and haulage routes are finalised. These measures would be developed as part of the site-specific traffic management plans to indicate how traffic would be controlled and managed during each stage of the construction.
The construction traffic management plan would contain the following information.
Proposed construction activities.
Estimated duration of the works.
Increased traffic volume by vehicle type.
Anticipated or designated routes for the delivery of materials and equipment.
Summary of the potential construction impacts on the road network and any feasible measures to reduce the forecast impacts.
TR-0695-C.doc Page 55 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Additional considerations would include:
Identification of haulage routes and ensuring impacts to local routes are minimised.
Identification of traffic management requirements during construction.
Ensure at least one lane of traffic is maintained in each direction at all times.
Maintaining the capacity of local roads.
Minimising impacts on the Great Western Highway and local traffic.
Providing access to local roads and properties.
Including methods for minimising road user delays.
Retention of local property and emergency access where practicable.
Provision of a swept path analysis to ascertain that sufficient manoeuvring space is provided for all vehicles at intersections along the haulage routes.
Warning signs to advise road users in advance of work zones and surrounding intersections.
Safety signage to be installed to warn construction vehicle drivers of the presence of cyclists and pedestrians.
U-turn facilities for construction vehicles where necessary. With respect to stakeholders, the CTMP would include:
Identification of the main stakeholders.
Roles and responsibilities of all stakeholders.
Contact details for all stakeholders.
The person responsible for developing, updating and implementing the plan.
Any required approvals and licenses. With respect to community consultation, the CTMP would include:
Letterbox drops to local residents advising of potential property access restrictions (if required).
Consult with affected landowners and residents prior to any impacts to access.
Provision to maintain safe access to bus services.
Provide safe access for pedestrians.
Signposting and advertising to warn motorists of proposed road closures and traffic diversions and other temporary traffic arrangements.
Advertisements in local newspapers.
TR-0695-C.doc Page 56 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Traffic control plans would be prepared as part of the CTMP for specific stages of work or locations as required. A review of temporary road work traffic control measures, signage and speed limits in areas of potential risk would also be undertaken.
The CTMP would also outline procedures to audit implementation of the plan and particularly to ensure safety aspects are being observed.
A list of the proposed mitigation measures during construction is provided below in Table 6-1.
Table 6-1: Mitigation measures for construction traffic impacts
Mitigation Design and pre-construction Traffic impacts to the users of the local and regional road network would be considered when developing the preferred design arrangement, such as:
Limiting the number of points where new alignments cross the existing road network.
Limiting the need to occupy areas of the existing road.
Identifying haulage routes for construction traffic.
Undertaking road condition surveys of local roads prior to construction.
Consultation with bus service operators.
Individual construction worksites At the individual construction worksites, the objective is to minimise traffic impacts by adopting the following guiding principles:
Planning construction through the use of construction staging and temporary roadworks to minimise interaction with the existing road network and night time freight vehicle movements.
Minimising the road space occupied by works, and the time of construction.
Minimising the impacts of construction works on local and regional traffic by using the new carriageway, as far as practical, for construction traffic.
Implementing traffic control measures only when necessary.
Maintaining property access for the duration of the construction, and where reasonable and feasible, provide alternative access in consultation with affected landowners.
Where possible the site access should try to provide a deceleration bay within the sites. Monitoring of weather conditions and undertake inspection of roads during fog, ice and snow conditions during the winter months. Identify any impacts to safety including driver sight distance and road pavement conditions.
Stop or restrict vehicle movements during periods of adverse weather conditions that may impact upon the road and the safety of workers.
TR-0695-C.doc Page 57 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
Coordinating works The objective is to ensure that road users do not experience excessive delays on their journeys, due to frequent road works. This can be achieved through:
Coordinating the delivery of construction materials, and the movement of construction plant and equipment to and from construction sites.
Consideration of any cumulative traffic impacts from nearby development and to ensure coordination of works and construction traffic movements.
Coordinating all RMS works, and any works by other agencies that affect traffic flow.
Coordinating with transport operators regarding schedules, abnormal loads and other events.
Identifying, evaluating, and documenting other routes (in consultation with local councils).
Coordinating with emergency services and managing incidents.
Adequate information The objective is to ensure that the highway users and local communities are provided with timely, accurate, relevant and accessible information about changed traffic arrangements and delays owing to construction activities. This is to be achieved through:
Suitable signage at work sites.
Selection of appropriate information (type and format), and the appropriate locations for information dissemination.
6.3. Vehicle movement plan
A vehicle movement plan (VMP) would be prepared as part of the overall CTMP. The VMP would assess construction related heavy vehicle movements per shift in to and out of the construction site/s.
TR-0695-C.doc Page 58 Great Western Highway Upgrade, Mount Victoria to Lithgow Alliance Forty Bends Upgrade REF Technical Paper 8: Traffic and Transport
7. Conclusion
The proposed Forty Bends upgrade is about 2.8 kilometres in length and would extend from a point about 470 metres east of the eastern end of Forty Bends Road to a point about 250 metres west of McKanes Falls Road, South Bowenfels.
Some changes to the existing local road network (including Forty Bends Road, Daintree Close and McKanes Falls Road) would also be required to connect the proposal to these roads and property access points.
Intersection upgrades would be implemented at Forty Bends Road and McKanes Falls Road with the Great Western Highway and U-turn facilities provided on Forty Bends Road and McKanes Falls Road to improve road safety.
The design of the proposal has been completed in a manner to control access, using the access management principles to derive the design layout, thus eliminating conflict points, and concentrating vehicle movements to formalised intersections, further increasing safety.
Road and intersection performance would continue to operate at good Levels of Service during the construction of the proposal and once completed.
A number of design measures are proposed in conjunction with an active winter maintenance program to prevent the pooling of cold air on the road surface which would help reduce the formation of black ice.
A construction traffic management plan would be prepared to develop site-specific traffic management measures once the construction methods and haulage routes are finalised. These measures would be developed as part of the site-specific management plans to indicate how traffic would be controlled and managed during each stage of the construction.
