1 Introduction
Aphane Consulting CC was appointed by Gauteng Department of Roads and Transport to undertake a traffic study for the detailed design of K109 between Halfway House and Olifantsfontein, Johannesburg North. The K109 forms part of Gauteng Department of Transport (GDRT) future road network planning aimed to enhance connectivity within the province and to other provinces. The K109 in its entirety is planned to run in a north-south direction commencing from R101 (Old Pretoria Main Road) in Halfway House and terminating at M39 in Brakfontein. Figures 1and 2 shows the extent of K109 between Halfway House and Olifantsfontein and Figure 3 shows the K109 in the context of the future road network planning. The purpose of this study is to inform the detailed design of the route with regards to design standards that are applicable in terms of lane requirements, pavement design and access management.
2 Scope of Study
It is important to note that the study is not intended to deal with any proposed township applications or to provide an opinion on any application that has been submitted. The scope of the study entails the following: To determine the expected heavy vehicles along the corridor for the estimation of E80 axial loading to be used in the pavement design Estimate expected future traffic volumes over 20 year design period to establish typical design requirements for the road as a single or dual carriageway; Conduct capacity analysis to determine concept designs of the proposed intersection as well as the required intersection control; Review the proposed access/intersection positions against the Road Classification and Access Management (RCAM) requirements and recommend changes if necessary; and Assessment non-motorised transport (NMT) and public transport requirements along the proposed corridor.
3 Background to K109
The K109 forms part of GDRT future road network planning aimed to enhance connectivity within the province and to other provinces. The K109 is planned to run in a south-north direction commencing from R101 (Old Pretoria Main Road) in Halfway House and terminating at M39 in Brakfontein. This route will provide an alternative to the congested M1 and Old Pretoria Road (R101) as well as Allan Road in connecting Midrand and Centurion. This study, however, only addresses the portion of K109 between Halfway House and R562 (K27) in Olifantsfontein. The route alignment is planned off bituminous Dale Road through undeveloped land, round the Glen Austin nature reserve, to join the alignment of
TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 1
K109 TRAFFIC IMPACT STUDY

Van Rebeeck Road and thereafter stretches over undeveloped land until its intersection with R562 (K27). Van Rebeeck Road intersects with George road and Olifantsfontein Road (D795) along its length.
4 Surrounding Road Network
Allan Road
Allan Road/ Modderfontein Road runs in a north- south direction starting from Dale Road and intersecting with Douglas Road, George road and Olifantsfontein Road and terminating at its intersection with R562 (K27). Allan Road/ Modderfontein Road functions as a class 3 road, a minor arterial. It is a single carriageway with one lane in each direction.
Dale Road
Dale Road functions as a connector road road running in an east –west direction. Dale road starts from Old Pretoria Road (R101), intersects with Allan Road/ Modderfontein Road (M38) and several local access roads to the surrounding residential areas along its length and ends as a cul de sac in Kaalfontein. Dale Road is a single carriageway road with one lane in each direction.
Van Reibeeck Road
Van Rebeeck Road is a gravel Road which functions as an access road on the western boundary of Glen Austin AH residential area.

Douglas Road
Douglas Road functions as a local access road within the Glen Austin AH residential area. It runs in an east-west direction has one lane in each direction throughout its length. Douglas Road is 5m wide and has traffic calming in the form of speed bumps.
George Road
Similar to Douglas Road, George Road functions as a local access road within the Glen Austin AH residential area. It also runs in an east-west direction starting from Van Rebeeck Road, intersecting with Allan Road/ Modderfontein Road and Old Pretoria R oad ending as a cul de suc just before the N1. George Road has one lane in each direction throughout its length. It is 5m wide and has traffic calming in the form of speed bumps
Olifantsfontein Road
Olifantsfontein Road also runs in running in an east-west direction. It connects Olifantsfontein to the north-western suburbs of Johannesburg. Olifantsfontein starts as a class 3 road at its intersection with R562 (K27) until its intersection with the Old Pretoria Road. Thereafter, it proceeds as a class 2 road to Plantation Road in Midrand.

R562 (K27)
R562 (K27) is a provincial road running in an east-west direction that extends between R101 and R21 in Tembisa. Olifantsfontein is a dual carriageway road with two lanes in each direction.
5 Existing Traffic Volumes
Detailed traffic counts were undertaken on Thursday, 19 June 2014 as part of the K109 corridor study at the following intersections: Allan Road/Dale Road; Dale Road/Archefish Drive; Dale Road / Licensing offices Access; Douglas Road/ Van Riebeeck Road; George Road/ Van Riebeeck Road; Olifantsforntein Road / Van Riebeeck Road; and Olifantsfontein Road / R562 (K27) These traffic counts are summarised in Figures 4 and 5 for the AM and PM peak hours respectively. The following observations can be made: Allan Road: The AM two-way traffic flow between Dale Road and Douglas Road is 937veh/hr. There is approximately a 70:30 split in north: south traffic flow. During the PM this section of the road experiences similar traffic volumes (914veh/hr.) as the AM peak hour with an approximate balanced split in north: south flow; Dale Road: The section of Dale Road between Allan Road /Modderfontein Road and Archerfish Drive has two-way traffic flow of 1075veh/hr during the AM peak hour with a 30: 70 directional split in east: west flow. The PM two-way traffic flows are slightly higher at 1274veh/hr with a directional split of 75:25 in east: west flow; Van Riebeeck Road: This road has low traffic volumes, not exceeding 80 veh/hr during the AM and PM peak hours; George Road: The two-way traffic flow of George Road just before its intersection with Van Riebeeck Road are less than 50 veh/hr for both the AM and PM peak hours;
TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 4
K109 TRAFFIC IMPACT STUDY
APHA NE CONSULTING GAUTENG DEPARTMENT OF ROADS AND TRANSPORT
Douglas Road: Similar to George Road, traffic flows on Douglas road before its intersection with Van Riebeeck Road are very low, not exceeding 60veh/h during the AM and PM peak hours; Olifantsfontein Road: The two-way traffic flow on Olifantsfontein Road from R562 (K27) to Van Riebeeck Road is approximately 640veh/hr and 1140veh/hr during the AM and PM peak hour respectively; and R562 (K27): The two-way traffic flow east R562 (K27) / Olifantsfontein Road intersection ranges between 2850 and 3200veh/hr during the AM and PM peak hours. The road section west of R562 (K27) / Olifantsfontein Road intersection has flow ranging between 2000veh/hr and 2300 veh/hr. This is a result of significant turning movements from the R562 (K27) eastern approach onto Olifantsfontein Road and vice versa.
6 Trip Generation
Once developed, the K109 is expected to have similar characteristic to Allan Road/ Modderfontein Road (Modderfontein Road). Although the link is not expected to generate new traffic on the network, it is however expected to trigger traffic re-distribution and diversion on the surrounding road network. An assessment of the expected traffic diversion and re-distribution is given in Section 7.
7 Traffic diversion and re-distribution assessment
Key infrastructure interventions, such as the proposed K109 link, usually affect traffic patterns in the surrounding road network based on the notion ‘build it and they will come’. The most likely impact could be re-distribution of traffic from congested parallel routes to take advantage of the additional network capacity. A SATURN model, which was developed for traffic impact assessment in the Waterfall and Modderfontein area was used to assess the traffic diversion as a result of the introduction of the link. The model does have high level representation of the area and include the major roads in the wider area. However, the model lacks sufficient detail for intersection capacity analysis in the immediate vicinity to the location of the new link. Due to the complicated nature of the traffic diversion assessment, it was decided that the SATURN model be used for an assessment of traffic diversion and re-distribution whilst the detailed intersection capacity analyses were carried out using data from manual data count. Thus, the traffic that is expected to be diverted to the proposed link was superimposed on traffic flow data from manual turning counts. The graphics below illustrate the traffic diversion effect of the proposed K109 link. The graphics represent a ‘with and without’ K109 scenarios. The blue (negative) numbers represent traffic diversion from the link, and the green (positive) numbers represent an attraction to the road links. The analysis was carried out for both AM and PM scenarios.

Picture 1: K109 Traffic diversion (AM)
Picture 2: K109 Traffic diversion (PM) The analysis demonstrated that the link could attract about 600 vehicles in either the northbound or southbound direction during the AM peak hour, from the surrounding road network, most notable Allan Road, Republic Road and the R101. In the PM peak hour the link is expected to attract about 650 and 400 vehicles, in the northbound and southbound directions respectively.

The traffic attracted to the link in the diversion assessment was superimposed on the traffic count data for capacity analysis. The model traffic distribution was used to distribute the attracted traffic along the proposed K109 link. Figures 6 to 9 show the traffic distribution for ‘with and without’ K109 scenarios for the base year (2014)
8 Forecast Traffic
According to the South African Engineering Service Contribution Manual for Municipal Road Infrastructure COTO TMH 15 (2012), Structural design life for road pavements is typically 20 years. Thus for the purposes of pavement design the traffic volumes have been forecasted to year 2034. A 5-year design horizon (i.e. 2019) was used in accordance with the guidelines of traffic impact studies for the assessment of intersection capacity. The future levels of traffic have been estimated based on the following: Manual turning count data; Traffic diversion assessment; Traffic yearbook data by the Gauteng Department of Roads and Transport (GDRT, 2010 & 2011) The base year (2014) was derived from the traffic diversion using the Modderfontein SATURN model and the manual traffic counts as discussed in the previous section of this report. The growth rate per annum was established using Traffic yearbook data by the Gauteng Department of Roads and Transport (GDRT, 2010 & 2011). The latest counts (2012 and 2013) data that was available from the GDRT but was not used as it was from different seasons and did not offer a good basis for comparative assessment. However the 2010 and 2011 data is comparable as the counts were conducted during the same period of the year. Counts station ‘0325’, Zuurfontein Roa d between Chloorkop and Modderfontein was deemed to be the closest representative count site for purposes of traffic growth and Average Daily Traffic (ADT) estimates on the proposed K109 link. From the count data, it was established that there has been a 3.5% negative traffic growth during the peak hours as well as throughout the day between 2010 and 2011. A view was therefore taken that a 1% pa (positive) growth rate would be a more suitable growth rate for this area. Future peak hour traffic demand is depicted in Figures 10 to 13. Variables that could be used for peak hour / ADT traffic conversions were extracted from the GDRT count data and are tabulated below: These variables were applied to the peak hour traffic flows to estimate Average Daily Traffic (ADT) and Average Daily Truck Traffic. The final (ADTT) estimates are given in Passenger Car Units (PCUs) or Equivalent Vehicle Units (EVUs).

It is recommended that E80 value be based on these volumes. The year 2034 estimated two-way peak hourly total traffic volume for the proposed K109 is 1510 veh/hr. According to the Gauteng Department of Public Transport, Road and Work Road Design Manual, a single carriageway with two lanes (one lane in each direction) would provide sufficient capacity for the proposed K109.
9 Analysis Method and Scenarios
The base year (2014) has not been analysed as the existing volumes along Van Riebeeck Road are low and by observation, the current traffic operations are deemed acceptable. The upgrade of this route to full K-route standard requires that all informal/temporary accesses on the proposed alignment are closed and that access is taken from approved intersection points that were determined during the preliminary design of this route (see Appendix A). In addition to this, existing metropolitan roads, provincial roads and future K-routes which cross the K109 were also considered when evaluating the future traffic flows.
9.1 Access assessment In general road networks are designed to serve two purposes and that is to provide mobility and access of people and goods between their origins and destinations. Access management is a systematic control of access to developments so as to maintain road safety for all users whilst ensuring efficient usage of the road network by balancing accessibility and mobility. This is achieved by the carefully planning of access location, access and intersection design and operation of driveways, median openings and street connections, among other road network characteristics. The South African Road Classification and Access Management Manual classifies and defines urban mobility and access as shown in diagram below which illustrates the interaction and transition between mobility and accessibility.
TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 9
K109 TRAFFIC IMPACT STUDY
APHA NE CONSULTING GAUTENG DEPARTMENT OF ROADS AND TRANSPORT
Functional road classification – balancing mobility and accessibility
The K109 is planned to function as a Class 3 road, a minor arterial, which means limited access will be allowed. The South African Road Classification and Access Management Manual recommends a spacing between intersections of 600m +/- 20% on Class 3 roads. These guidelines are in accordance with GDRT standards. A review of the preliminary design indicates that the proposed intersections along the proposed K109 meet the minimum spacing requirements for a class 3 road.
9.2 Crossing Roads For the purposes of this study, K109 is planned to intersect with the following roads: Dale Road: The K109 is planned to be the third leg forming a T-junction with Dale Road ; Douglas Road: Douglas road would be extended to intersect with K109 to form a T- Junction; George Road: The planned future intersection would be at the current location of the George Road and Van Riebeeck Road T-junction; Olifantsfontein Road: The planned future intersection would be at the current location of the Olifantsfontein Road and Van Riebeeck Road intersection; and R562 (K27): The propose K109 is planned to be the third leg at its intersection with R562 (K27) forming new T-junction. Each of these intersections has been analysed in this study.
TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 10
K109 TRAFFIC IMPACT STUDY
APHA NE CONSULTING GAUTENG DEPARTMENT OF ROADS AND TRANSPORT
9.3 Scenarios Only one scenario was assessed: 2019 AM and PM peak hour future traffic using 1% per annum growth in background traffic as previously articulated in section 8 of this report.
9.4 Analysis Software The proposed intersections along K109 were assessed using SIDRA Intersection Software. The purpose of the analyses was to determine concept designs of the proposed intersections as well as the required intersection control by considering level of service (LOS), volume / capacity (v/c) and delays. The performance criteria for the intersections are indicated in Table 4 below. The level of service (LOS), delay and volume / capacity (v/c) have been defined in accordance with the Highway Capacity Manual (HCM 2000) . In addition, if a signal controlled intersection operates at a v/c ratio of more than 0.95, it is regarded as operating at capacity. Table 4: Performance Criteria

9.5 At-grade Intersections As previously stated, the projected traffic flows have shown the need for the K109 to be a single carriageway facility, with one traffic lane per direction. At the intersections the approaches need to be widened to allow for separate turning movement lanes. A 5 year horizon was applied for the assessment of the intersection capacity analysis also using 1% per annum growth rate. The diagrams below outline the proposed intersection configurations.

The results for the AM and PM peak hours shown in Table xx demonstrate that the proposed intersection layouts are expected to operate at good level of service.
10 Public Transport and Non-Motorised Transport
A notable number of pedestrians and cyclists were observed using Dale Road and Van Riebeeck Road during a site visit. These are likely Thembisa residents who rely mostly on public transport and walking and cycling to access places of employment in Glen Austin and the surrounding areas. It is likely that over time these movements will increase thus proper pedestrian accommodation along the K109 corridor is considered important to the extent that it is suggested that a pedestrian walkway of approximately 1.8m width is constructed along western side of K109. This walkway would be wide enough to also accommodate cyclists. It is also recommended that the upgraded intersections should be designed in line with Universal access principals. The only public transport services provided in the area are taxis travelling along Allan Road, Olifantsfontein Road and the R562 (K27). Once the K109 is constructed, taxi services can be expected to run on this corridor as well. Thus it is recommended that proper taxi/bus pick-up and drop-off facilities should be provided in accordance with the latest GDRT guidelines for such facilities along K-routes at the following intersections: K109/ R562 (K27); K109/ Olifantsfontein Road; K109/ George Road; K109/ Douglas Road; K109/ Dale Road.

11 Conclusions and recommendations
Aphane Consulting CC was appointed by the Gauteng Department of Roads and Transport to undertake a traffic study inform the detailed design of a portion of K109 between Halfway House and Olifantsfontein, Johannesburg North with regards to design standards that are applicable in terms of lane requirements, pavement design and access management. The following conclusions can be drawn from this analysis: The 20 year traffic volumes for the proposed K109 link have been estimated to be approximately 19 000 vehicles per day of which 640 are heavy vehicles. It is recommended that E80 value be based on these volumes. The estimated year 2034 two-way peak hourly total traffic volume for the proposed K109 is 1800 veh/hr. According to the Gauteng Department of Public Transport, Road and Work Road Design Manual, a single carriageway with two lanes (one lane in each direction) would provide sufficient capacity for the proposed K109. The K109 is planned to function as a Class 3 road, a minor arterial, which means limited access will be allowed. The South African Road Classification and Access Management Manual recommends a spacing between intersections of 600m +/- 20% on Class 3 roads. A review of the preliminary design indicates that the proposed intersections along the proposed K109 meet the minimum spacing requirements for a class 3 road. The following intersection layouts and intersection control are recommended for five proposed intersection along the proposed K109: o R562 (K27)/K109 Proposed to be a signalised T-junction. R562 (K27) eastbound – dual carriageway with double straight ahead lanes and one 60m right turning slots into K109; R562 (K27) westbound – dual carriageway with a single 60m separate left turning slot and double straight ahead lanes; and K109 northbound – single carriageway with a 60m right turning slot and single left turning lanes. o Olifantsfontein Road (D795)/K109 Proposed to be a signalised four legged intersection. Olifantsfontein Road (D795) eastbound – single carriageway with a 60m right turning lane, one through lane and one 60m slip lane one through left right into K109; Olifantsfontein Road (D795) westbound – single carriageway with one through and left turning lane and a single 60m right turning slot; K109 northbound – single carriageway with a 60m right turning slot, a single lane for the through and right turning movements and a single lane for the through and left turning movements; and.

K109 southbound – single carriageway with a 60m right turning slot and a single lane for the through and left turning movements. o George Road/K109 Proposed to be a priority controlled T-junction with K109 as the major road; George Road westbound – single carriageway with a single lane for left and right turning movements into K109; K109 northbound – single carriageway with a single through lane and 60m left turning movements; and. K109 southbound – single carriageway with a 60m right turning slot and a single through lane. o Douglas Road/K109 Proposed to be a priority controlled T-junction with K109 as the major road; Douglas Road westbound – single carriageway with a single lane for left and right turning movements into K109; K109 northbound – single carriageway with a single through lane and 60m left turning movements; and. K109 southbound – single carriageway with a 60m right turning slot and a single through lane. o Dale Road/K109 Proposed to be a priority controlled ‘Y’ shaped intersection with K109 as the major road; Dale Road westbound – single carriageway with a single lane for left and right turning movements into K109; K109 northbound – single carriageway with a single through lane and 60m right turning movements; and. K109 southbound – single carriageway with a 60m left turning slot and a single through lane. The upgrade of this route to full K-route standard requires that all informal/temporary accesses on the proposed alignment are closed and that access is taken from approved intersection points that were determined during the preliminary design of this route. There are currently a notable number of pedestrians and cyclists were observed using Dale Road and Van Riebeeck Road during a site visit. It is likely that over time these movements will increase thus proper pedestrian accommodation along the K109 corridor is considered important to the extent that it is suggested that a pedestrian walkway of approximately 1.8m width is constructed along both sides of K109. These walkways would be wide enough to also a accommodate cyclists.
