1 General

1.1 Scope

This Specification sets out the general requirements for the installation of equipment which provides active level crossing protection on vehicular and pedestrian level crossings on CRN’s rail system within New South Wales.

This specification applies to public road level crossings and pedestrian level crossings. It is applicable to the construction of new crossings and the upgrading and maintenance of existing level crossings.

This specification does not cover the requirements for passive level crossing protection although some aspects of the active pedestrian crossings will be applicable to both.

Passive protection requirements are included in CRN CS 520.

This document is to be read in conjunction with CRN Specifications:-

- - CRN SD XXX series Signalling Design Principles which defines the operating parameters for level crossings, - CRN SE 038 Manufacture and Assembly of Level Crossing Equipment - CRN SC 021 Construction of Cable Route and Associated Civil Works which defines post foundations, - CRN SC 015 Specification Installation of Trackside Equipment which defines installation requirements for associated works.

Level crossings represent a significant safety risk to passengers, train crews, pedestrians and motorists.

The design of level crossing and protection equipment utilised, is to be undertaken only after the safety risk and all other factors have been fully assessed and resolved and is to be based on relevant Australian Standards and Codes of Practice and requirements specified in this document.

Level crossings are installed to provide a safe track crossing, at grade, for road, pedestrian and stock traffic. Level crossings may also provide access points for on and off tracking combination road/rail vehicles.

A safe crossing equates to the ability to:-

- Warn users of the approach of conflicting traffic with sufficient time for protective action to be taken.

- Warn users of the existence of a level crossing.

- Allow for the passage of specified road, rail and pedestrian traffic.

The methodology in this standard is applicable to installation of equipment on new level crossings and for the upgrading of the protection of an existing level crossing.

The type of protection or control applied to a particular level crossing is determined by a formal risk assessment process which considers:-

- Road/rail/pedestrian traffic volumes and speed, - Sight distance, - Road and rail track alignment, - Roadside activity, - Accident history, and - Number of tracks.

Level crossing configurations are determined in consultation with the relevant Road Authority and with reference to the guidelines detailed in AS1742 part 7, the RTA Traffic Engineering Manual Section 6, and this Standard.

The level of protection to be applied at road crossings is to established using ALCAM and the sight distance requirements detailed in section 7 of CRN CS 520.

The level of protection to be applied at pedestrian crossings is to established using the sight distance requirements detailed in section 8 of CS 520.

1.2 Operation, Testing and Commissioning of Level Crossing Protection

The level crossing protection specified herein shall operate in accordance with the principles and circuits in CRN SD 000, CRN SD 018 and CRN SD 025 and shall be tested and commissioned in accordance with CRN SC 011 and CRN SC 013.

The following forms located in CRN SC 012, are also to be used with the construction and commissioning of Level Crossings:

- Level Crossing Site Inspection Form. - Level Crossing Site Inspection. - Stakeholder Site Inspection and Authority to Commission. - Gated Pedestrian Crossing Assessment Sheet.

1.3 Warranty

Completed level crossing protection systems shall be warranted free of defect in installation for a period of 12 months from the date of commissioning.

All of the equipment installed, including consumables, shall be warranted as complying with this or any referenced specification and as being fit for purpose.

1.4 Quality

The standard of materials and workmanship, including the workmanship involved in installation, shall ensure that the installed system is fit for purpose over the lifetime of the asset in its physical and operational environment.

Quality of materials and workmanship shall also ensure that the necessity for regular preventative maintenance tasks to retain the safety, reliability and useability of the asset over its lifetime is minimised.

4 Road Crossings

4.1 General

For each public access level crossing it shall be necessary to come to an agreement with the Roads and Traffic Authority or local road authority and other stakeholders as to, but not limited to :-

- Any necessary improvements to road approach alignment or surface - The layout of the equipment - The type of protection and number of signals - Provision of kerbing and/or delineation - The requirement for Advance Warning Lights - The provision and installation of road signage outside the railway boundary - Traffic Light Interface.

In consultation with the sighting committee, site specific circumstances may determine a need for auxiliary light stands in addition to the main lights.

On reaching agreement, site plans and or site minutes detailing the proposed crossing layout shall be signed off by all involved parties.

Level crossing signals and signage installation for each level crossing shall comply with Australian Standard 1742 Part 7, additional drawing(s), specifications and site plan(s) issued by CRN. CRN standards shall take precedence.

4.2 Services

Where relocation of any service (e.g. water, gas, electricity etc.) is required, arrangements shall be made with the owner to have the relocation carried out.

If for any reason relocation of the service is found to be impractical, alternative proposals to avoid or span the service need to be considered.

4.3 RX-5 Assembly - Posts (Masts)

The RX-5 Assembly post arrangement shall comply with drawing M06-269.

For the RX-5 Assembly with Boom, the post arrangement shall comply with drawing M06- 203.

Refer to Figures 1 and 2 for examples.

Cantilever posts or gantries over roads will only be permitted where a clear safety improvement can be demonstrated, and on approval of the Principal Signal Engineer.

4.4 RX-5 Assembly Mast Installation

RX-5 Assembly masts and RX-5 Assembly with Boom masts on each side of the level crossing shall be positioned such that no part of the centreline of the masts, or boom tip is closer than 3.5 metres from the nearest rail.

To allow sufficient clear space for safe maintenance access of the mechanism and counterweights, no infrastructure such as fencing, shall be permitted to be located within 2 metres of the rear of the centreline of the boom gate mast. The rear being defined as the side where the mechanism is fitted to the post.

Where overhead cables are located within 3m (for voltages up to 132kV) horizontally of a proposed boom post, the supply authority shall be contacted to determine the required safe horizontal and vertical clearances from the boom tip. In some circumstances this may require the OHW to be relocated or run underground.

Where the boom is considered to be of sufficient length so as to be able to fall when struck, into the 1500Vdc OHW traction line, a boom of fibreglass construction in lieu of the standard aluminium/fibreglass composite construction, may be considered.

The position of the light or boom mast relative to the road edge, edge marking or kerb will depend on:-

- The road approach speed, which will define the “clear zone”1 - Any physical restrictions imposed by the site - Vehicle drivers sighting of the lights

1 The “clear zone” is the distance from the road edge or edge marking which is, whenever possible, to be maintained clear of obstructions. This provides an area in which a vehicle can run off the road and recover.

2 Elsholz Redirective Kerb is suitable for low impact angles <15° in 60 to 70km/h speed zones.

- Boom arm length limits.

In most instances, site restrictions and/or sighting requirements and/or limiting boom lengths will necessitate placing the masts within the clear zone.

Where this is the case, a documented risk analysis shall be carried out to determine the best method of minimising the risk posed by the mast. This may take the form of barrier kerbing or delineation or both. Since space restrictions at level crossings usually preclude the installation of adequate guardrail end protection sections, ‘W’ style (Armco) guard rails cannot be used to protect the installation from errant motor vehicles.

Where non-frangible equipment is to be placed within the ‘clear zone’, guidance should be sought from the local road authority and/or latest version of the RTA Road Design Guide. Refer to document titled ‘Traffic Engineering Manual, Section 6. Safety Barriers for Roads and Bridges, Road Design Guide, May 1996.’

While there is a reduction in rigidity provided by the cast aluminium mast base, this arrangement cannot necessarily be classed as “frangible” and on suburban roads supplementary protection shall be provided in the form of barrier kerbing.

Consideration should be given to the use of Elsholz Redirective Kerb2 at the boom posts in suburban environments. Redirective kerb may only be installed with the approval of the local road authority.

4.4.1 Positioning of Masts ≤ 60kph

Figures 2(a) to 2(f) provide guidance on positioning of masts and delineation relative to the road edge for installations in suburban roads with a speed ≤ 60kph. As an absolute minimum, the centre line of the light / boom standard shall never be less than 1450mm from road edge, road edge being defined as rising edge of kerb as applicable to Figure 2(a).

4.4.2 Positioning of Masts >60kph

Figures 2(g) and 2(h) provide guidance on positioning of masts and delineation relative to the road edge for installations in urban roads with a speed >60kph. The offset of 3.5m is the desirable offset. An offset of 2.5m should only be a considered if the 3.5m offset cannot be achieved - reduced offsets will increase the probability of a vehicle impact with the installation

4.4.3 Installation of additional (auxiliary) light standards of Masts

Where site conditions require the installation of additional (auxiliary) light standards in urban areas without kerbs, as an absolute minimum, the centre line of the light standard shall not be less than 2500mm from road edge, road edge being defined as edge of bitumen or fog line. Guidepost and or kerb delineation treatments shall be determined as per clause 3.1.

4.5 RX-5 Assemblies

4.5.1 Flashing Road Traffic Signals

RX-5 Assemblies are typically available in two lamp unit (uni-directional) and four lamp unit (bi-directional) form.

Note that for level crossings without booms, where front and back light units must be sharply angled to one another, the assemblies shown for boom installations may be required to achieve the required angle.

The centre of the lamp units shall be 2600 – 2800mm above rail level.

Additional crossarms, where required, shall be mounted a minimum of 625 mm above the basic crossarm assembly.

Where a retro-fit post extension is required, it shall be manufactured according to drawing M06-257.

A typical RX-5 Assembly is shown in Appendix A Figure 1.

At level crossing sites with traffic light controlled intersections located immediately before and or after the level crossing, where a safety improvement can be demonstrated, on approval of the Principal Signal Engineer, the mounting of a traffic signal with red/yellow aspects only, may be permitted on the RX-5 Assembly post. In the foregoing configuration, the boom with mechanism would be mounted on a separate post. Refer to drawing M06- 266 for construction guidelines.

Note: Incandescent light units are not to be used for new works or upgrading of existing works.

4.5.2 Booms and Boom Lights

The nominal length of a boom shall be measured from the centre of the main shaft within the barrier machine to the tip of the boom.

Unless otherwise stipulated in the particular specification, the tip of the boom shall not be closer than 200 mm to the centre line of the carriageway for undivided roads and not beyond the near or far edge of the median strip on divided roads.

Refer to drawing M06-249 for standard boom kit selection and drawing M06-240 for light spacing guidelines.

The gate mechanism shall be mounted so that the bottom of the boom arm in the horizontal position will be between 1000 and 1250mm above road level. Refer to drawing M06-203 for general arrangement details.

A typical RX-5 Assembly with boom is shown in Appendix A Figure 2.

Where boom length exceeds 7.25m or approved boom skirts are fitted, a high wind support shall be fitted to the gate mast.

Where boom length exceeds 9140mm, an approved Buffer Leg Assembly shall be fitted to the tip of the boom and a High Wind Bracket fitted to the mast.

Boom lights shall be visible to road traffic on both sides of the level crossing but preferably not to the train driver.

The boom lights shall be positioned on the boom such that each traffic lane has at least one light in it.

Note:

Incandescent light units are not to be used for new works or upgrading of existing works.

4.5.3 Enlarged Background

When the road alignment is such that the sun will rise or set behind the level crossing signals when viewed from the road approaches, a large one piece background as detailed in drawing M06-258 may be fitted to the RX-5 Assembly. This background shall be additional to the standard backgrounds fitted to the light units. One only background is required per pair of flashing signal lanterns.

4.6 Audible Warning Devices

Audible alarms/warnings shall take the form of bells and provide an additional warning to the visual warning provided by red lights. The effective audible range of the warning is determined by whether vehicles windows are open and or sound systems etc are operating. Audible warnings are increasingly, primarily provided for the purpose of warning pedestrians.

Bells may be either solid state (electronic) or mechanical in their design.

The Western-Cullen-Hayes model 0777 electronic bell needs to be set to maximum volume in order to replicate the standard mechanical bell sound level. Refer to Specification CRN SE 038 for options and adjustment detail.

Mechanical bells are normally fitted with a metal hammer. A nylon hammer option is available for reducing the sound level in approved instances. Refer to Specification CRN SE 038 for further details.

Where suppression of audible warning devices is considered necessary, the arrangement shall comply as permitted under Design Principles document CRN SD 018.

Where there is no bell mounted on top of the post, pipe sealing caps shall be provided.

4.7 Signage

Refer to AS1742.7 for general information on the below-referenced standard signage types:-

- R6-24A, R6-25B, W7-2-2A, R6-9, W7-4B and 4C, W7-14-3, D4-3, G9-58, G9-67-2 and RX-9. - Rail Authority Basic Signage.

The minimum requirement for active crossing signage shall be:-

- "Railway Crossing" sign R6-25B (often described as the ‘Confederate flag’ version), shall be supplied to drawing M06-263. One on each side of the level crossing mounted on the RX-5 Assembly post. Note: The alternative style "Railway Crossing" sign R6- 24A together with the "Tracks" sign W7-2-1A may be used for high wind applications such as on the tip of an overhead cantilever post. - "Tracks" sign W7-2-2A shall be supplied to drawing M06-212. One on each side of the level crossing mounted on the RX-5 Assembly post. Refer note below. - "Stop On Red Signal" sign R6-9 shall be supplied to drawing M06-212. One on each side of the level crossing mounted on the RX-5 Assembly Post. - Train Drivers Approach sign W7-4B shall be supplied to drawing M06-213. One on each railway approach to the level crossing at the point at which the train initiates the level crossing operation.

D4-3 width markers may be required where the conspicuousness of the crossing needs to be enhanced. Civil discipline is responsible for RX-9 and D4-3(L & R) width marker signs. These signs are generally required where the road lane at the crossing reduces in width, at crossings located on sharp curves, where a pedestrian crossing or other equipment is located close to or on the edge of a road without kerb and guttering and within the clear zone and at urban crossings. Refer to examples in Appendix A Figures 2(f) to 2(h).

Where D4-3 width markers are required, they shall be installed to both sides of the road, both sides of the crossing.

Refer to examples in Appendix A Figures 2(f) and 2(h).

4.7.1 Road Authority Signage

The Road Authority responsible for the particular road(s) involved, provides guideposts, approved barrier kerbs and additional road approach signage.

As a minimum, ensure that the Road Authority provides approach warning sign W7-4B or C, one on each side of the level crossing, placed where shown in AS1742.7.

Ensure that the Road Authority provides G9-67-2 ‘Keep Tracks Clear’ signage where applicable. When issued by CRN, the ‘Keep Tracks Clear’ sign shall be supplied to drawing M06-212.

Refer to examples in Appendix A Figures 2(d) and 2(e).

4.8 RX-5 Assembly Foundations

The top of the foundation is to be between 25 and 100mm above ground level.3 Also refer to figures 1 and 2(a) for guidelines.

4.8.1 Posts Without Boom

Pre-cast foundations for 114mm OD. RX-5 light posts shall be in accordance with the latest version of drawing M01-301. Foundation bolts shall be not less than 24mm diameter for signals on 114mm OD. posts.

4.8.2 Posts With Boom

Mainline 140mm OD. signal post foundation designs are generally suitable for RX-5 light posts with boom less than 9.2m long and mast height less than 4m.

Pending assessment of local ground conditions, for 140mm OD. RX-5 light posts with boom up to 12m long, refer to table on drawing M01-310 for guidance.

4.9 Road Pavement Markings

CRN has adopted the requirements of AS1742.7 and applied them to private and public level crossings.

3 Ground level is taken at the position of the foundation. This may be above or below road level. In country locations, ground level is usually taken as top of rail.

Pavement markings shall comply with AS1742.7 and shall be used on sealed roads on approaches to, and at, railway level crossings, as applicable.

Ensure that the Road Authority provides:-

- Holding / Stop Line, to indicate the safe position for vehicles to stop, to avoid conflict with a train. Refer to example sketches in Appendix A. - ‘RAIL X’ pavement marking, where required. - No overtaking lines on the approaches to, and over the crossing where applicable. - Box markings (queuing) where applicable. Where box markings are installed, ‘Keep Tracks Clear’ signage is required. Refer to examples in Appendix A Figures 2(d) and 2(e).

4.10 Cable Trenching

Cable trenching, under-line and under-road crossings for cable/wiring to Flashing Road Traffic Signals, boom mechanisms and any equipment associated with the control and operation of the level crossing shall be to the requirements of CRN specification CRN SC 021.

Cable trenching from the level crossing location to Advance Warning Lights shall be to the requirements of AS 3000.

4.11 Alignment of Flashing Road Traffic Signals

4.11.1 Requirement

Flashing Road Traffic Signals shall be aligned to provide the drivers of road vehicles with the maximum possible warning of the stop indication commensurate with the road speed limit approaching and over the level crossing.

The motorist must be able to sight the warning indication, either the Flashing Road Traffic Signals or the Advance Warning Lights at a safe stopping distance from the level crossing.

Safe stopping distances, which include driver’s reaction times, are:-

Vehicle Speed Safe Stopping Distance (m) Sighting (kph) Distance (m) Car Semi Trailer B-Double 40 45 65 67 - 60 77 116 120 130 70 - - - 175 80 120 184 191 200 90 - - - 250 100 175 275 286 300 110 - - - 300 120 250 - - -

Table 1

For most straight or near straight approach conditions the left side lanterns facing approaching traffic are to be focused for the long range view. The back lanterns of the signal on the other side of the crossing are to be focused for the short range view and for a vehicle(s) stationary at the stop line.

Typical focusing plans are shown in Appendix B (incandescent lights) and Appendix C (LED lights).

For multi-lane roads, both the left side light units and any light units on the median strip or on the front of a cantilever / gantry are to be focused for the long range view. Back light units on the signals on the other side of the crossing and back light units on a gantry or median strip are to be focused for the short range view and for a vehicle stationary at the crossing.

Where it is not possible for the front light units to be aligned for the long range view due to road geometry, any additional crossarms provided, whether on the same post, a separate post or a gantry are to be used for the long range view.

As the motorist must sight the light units at safe stopping distance, the front light units shall be aligned so that the axis of the beam intersects the road at that distance.

Where the approach to the level crossing is curved or over a crest, the degree of curvature and the blocking effect of the crest shall determine whether additional crossarms or post assemblies, cantilevered arms or Advance Warning Lights are required to provide visibility to the motorist at the safe stopping distance from the level crossing.

Where possible obtain vehicle approach speed information from the Roads and Traffic Authority. This will be the 85th percentile speed for the section of road leading to the crossing.

If this information is not available, for straight roads use the speed limit, for curved approaches use advisory speed signs and add 20 to 25%. E.g. if the advisory is 75kph assume an approach speed of 90 – 95kph.

Note:

The road speed within 50 or so metres of the crossing should not be used to estimate vehicle approach speed. E.g. if a road with a 100 kph speed limit parallels the railway then turns sharply to cross the line, do not use the curve speed to estimate vehicle approach speed. A vehicle may be able to negotiate the curve to the crossing at say 45 kph but would need to be at 25 - 30 kph entering the curve to be able to stop safely before the crossing.

4.11.2 LED Flashing Road Traffic Signal Alignment Procedure

Three persons (including one to act as the viewer’s lookout for road traffic) are required to align level crossing Flashing Road Traffic Signals.

Note: On roads with heavy traffic it will probably be necessary to obtain RTA assistance to stop traffic while alignment is being carried out.

The alignment must be carried out in daylight.

The person aligning the light unit should first approximately align each lampcase to point towards the viewer with the indication beam approximately horizontal.

The light unit should then be rotated side to side and up and down until the viewer indicates the position of maximum visibility.

With curved road approaches, the viewer should then walk back towards the level crossing checking the visibility of the light units throughout the curve.

If there is significant loss of sight of the light units, then the lampcases will need to be re- aligned to compensate even if this slightly reduces the intensity at the original viewing point.

If the loss of intensity is such that the light units cannot be aligned to provide full coverage from the required sighting distance over the approach to the crossing, then either additional light units at the level crossing are required or Advance Warning Lights are required.

It is not necessary to make any special provision for the height of the viewer. A standing person’s eye level is a reasonable compromise between the eye levels of car and heavy commercial vehicle drivers.

Light units are to be checked for clear visibility4 under bright sunlight conditions with the sun directly above.

4.11.3 Front Light Units

The person who is to view the light units shall do so from the distance nominated in section 5.3.1 for the road speed limit applying to the approaches to the level crossing or at the maximum available sighting distance, whichever is less. The viewer should be positioned:-

- 1 -1.2 meters to the left of the road centre line, for two lane roads, and - Approximately 1 metre to the right of the lane dividing line for four lane roads.

For four lane roads both the left hand side front light units and the median strip front light units should be aligned to the same point.

4 While LED light units must meet the specified visibility distances for bright daylight conditions, intensity shall not be so high that significant impairment to night vision is caused to a motor vehicle driver approaching the crossing at night.

4.11.4 Back Light Units

For LED light units, the viewing position should be 10 to 15 metres ahead of the stop line. Refer to typical situation Figures No 7 to 11 in Appendix C for indicative beam visibility patterns.

For four lane roads, the median strip back light units [if fitted] should be aligned to the left lane and the opposite side back light units aligned for the right lane.

4.12 Advance Warning Lights

4.12.1 Application

Advance Warning Light (AWL) and sign assemblies are intended for use under the following circumstances:-

- Where it is not possible for the motorist to see the flashing road traffic signals at the level crossing at the safe stopping distances specified in Table 1. - The level crossing is subject to severe fog conditions and the road approach speed is more than 60 kph. - There are special circumstances such as a sharp downhill approach which would extend vehicle braking distances or regular queuing back from the crossing being hidden by a crest. - There is a very long, straight flat approach to the level crossing and motorist’s reaction times are likely to be longer than normal.

The larger assembly, detailed on CRN drawings M06-400 and M06-401 is intended for highway and major road application where the road vehicle approach speed is 80 kph or higher.

The smaller assembly detailed on CRN drawings M06-403 and M06-404, is intended for secondary roads or where the road vehicle approach speed is less than or equal to 80 kph.

A variation on the smaller sign, detailed on CRN drawings M06-405 and M06-406, is intended for applications where it is necessary to provide early warning of activation of a level crossing on a side road where there is a very short distance between the stop line and the road intersection.

Note: Incandescent light units are not to be used for new works or upgrading of existing works.

4.12.2 Installation/Location Guidelines

The AWL assembly shall normally be installed to the left of the roadway but may, if necessary to provide adequate sighting around a left bend, be installed on the right hand side.

In rural areas without kerbs:- - The AWL assembly should be located so that the edge of the sign is not less than 2 metres or more than 5 metres from the road edge. - If there is a safety barrier system alongside the road, the edge of the sign should not be less than 600mm from the front of the barrier system. - The bottom of the sign should be 1.5 metres minimum above road level.

If in a kerbed area:- - The edge of the sign should not be less than 600mm from the kerb and - If over a formal footpath, the bottom of the sign must be 2.5 metres above the path. - Support posts must be clear of the path.

Foundations shall be according to drawing M06-407.

Note:

Depending on the site, AWL assemblies may be installed and/or maintained by the Road Authority or by CRN. Refer to RTA/CRN interface agreement titled ‘Interface Arrangements for the Installation and Maintenance of Joint Rail & Road Structures & Cabling at Level Crossings’.

CRN AWL assemblies shall be assembled according to the applicable above-referenced drawings.

4.12.3 Cabling

The cable from the level crossing location to the AWL shall be 3 core + earth power cable to AS 5000 parts 1 or 2 as applicable and shall be of the cross sectional area of sufficient size to allow correct operation of the AWLs. The buried conduit route shall be in accordance with the requirements of the local authority whose land the conduit is buried within.

4.12.4 Distance from the Level Crossing

It shall be possible for the motorist to sight the Flashing Road Traffic Signals at the level crossing from the AWL location or very shortly afterward so that a continuous warning is provided.

To achieve continuous or near continuous warning, the AWL shall be placed slightly inside the point at which clear sighting of the light units at the crossing is lost.

If this location is unsuitable due to restrictive sighting of the AWL or because there is insufficient space to locate the sign, the AWL may be moved further from the crossing by:-

- 30 m for 60 kph approach speed - 45 m for 80 kph approach speed - 55 m for 100 kph approach speed

Except where it is found necessary for two AWL assemblies to be provided, the maximum distance from the crossing to the warning lights should not exceed 350 m.

A W7-4 sign, at least, should always precede the AWL assembly.

A typical example of the location of the AWL assembly over a crest, is shown in Appendix C Figure 12.

4.12.5 Alignment

Both lights in the AWL assembly should be aimed 175 - 200m in front of the assembly for 80 kph and above and 100 to 125m for 60kph or to the maximum available sighting distance if this is less. Lampcases shall be level or tilted slightly downward.

The viewing face of the AWL assembly sign shall be aligned 5º past perpendicular to the direction of approaching road traffic. I.E. rotated approximately 5º away from the normal, to a line adjoining the edge of the roadway.

5 Pedestrian Crossings

Guidelines to the level of protection to be applied to pedestrian crossings, both independent crossings and those associated with roadways, is given in CRN CS 520.

Local considerations may, however, determine that a higher level of protection than indicated by the guidelines is necessary.

Crossings shall comply with the forms specified in AS1742.7 with exceptions as detailed in sections 5.1 and 5.2 below.

5.1 Standard Crossings

Actively protected standard pedestrian crossing layouts shall take the form defined as follows:-
