The indented bus bay should be located so that the Stopping Sight Distance for passing motorists is not compromised. It should be noted that drivers of buses departing from bus bays located on left hand curves have problems sighting vehicles approaching from the rear due to the curvature of the alignment. It is therefore not recommended to locate indented bus bays on left curve alignments unless it can be demonstrated that this problem has been overcome with modified bus bay geometry, refer Figure 6.3.4c.
Refer to the Main Roads Supplement to Austroads GRD Part 4a: Unsignalised and Signalised Intersections, Section 3.2.2 Table 3.2, for Safe Intersection Sight Distance values.
Figure 6.3.4.k Bus Bays on Opposing Carriageways
Normally, the crossfall within an indented bus bay should be 2% towards the adjacent traffic lane, as shown in Figure 6.3.4l and Figure 6.3.4m. Where the indented bus bay is located on a right curved superelevated road alignment, the indented bus bay crossfall shall be the same as the traffic lanes, as shown in Figure 6.3.4n. For drainage spread widths applicable to indented bus bays, refer to the Main Roads Guide to the Design of Piped Systems, Table 1.2.

Figure 6.3.4n Bus Bay on a Right Hand Curve
Where possible, drainage gully pits should not be placed within the length of the indented bus bay. Refer to Figure 6.3.4o.

220.127.116.11d Indented Bus Bay Facilities
A paved hardstand should be provided adjacent to the bus bay (if a footpath/shared path is not required or is not placed against the kerb) for pedestrians entering and alighting from the bus.
Where required, bus shelters shall be located in accordance with the following:
Refer to PTA's 'Public Transport Bus Stop Site Layout Policy', Austroads Road Design Part 4A: Unsignalised and Signalised Intersections, Chapter 3 - Sight Distance, and the Main Roads Supplement to Austroads GRD Part 4A.
18.104.22.168e Signs and Pavement Marking
Signs MR-RPK-6 (L or R) which are equivalent to R5-20 (L or R) in AS 1742.1 are to be used at extremities of the indented bus bay. For stand-alone signs, size "A" should be used. If the "Bus Zone" sign is used in conjunction with other parking series signs, the size will depend on the required sign layout. All other signs advising bus routes and times or associated with other facilities at the bus stop, are not traffic signs and are the responsibility of PTA.
Longitudinal yellow continuity lines as shown on Drawing 200331-092 shall be marked across the length of the indented bus bay, including tapers, in line with the kerb face or adjacent edge lines as shown in Figures 6.3.4p and 6.3.4q. Pavement marking shall be long life material in accordance with Main Roads Specification 604.

8.1.2 Types of Crossings
Application of Tactile Paving
Ground surface tactile indicators are designed to give warning of hazards, and directional information to pedestrians who are blind or have impaired vision. Refer to AS 1428.4.
Rather than apply such facilities everywhere, it is appropriate to implement tactile devices at selected intersections. These will normally be limited to kerb ramps at frequently used intersection or mid-block crossings in Metropolitan areas. In rural centres tactile paving is less commonly applied and the need to include in a specific project should be confirmed in consultation with the local LGA.
Section 6.3 of AS 1428.4 shows desirable layout and minimum dimensions. Note that in Western Australia, Type A or B tactile indicators are generally manufactured in 400mm modules (rather than 300mm) and thus the dimensions shown in Figure 5 will need to be increased accordingly. Where the direction of pedestrian travel across the roadway is angled from the kerb crossing, Type C indicators should be applied.
8.2 Mid-block Crossings on Roads
Reference Table 8.1 "Crossing features and considerations",for the last item in this table refer to drawing 9831-5649 Ramps and Grab Rail Details.
8.2.2 General Crossing Treatments
Reference Figure 8.1 Refer to Main Roads drawings 200331-139 & 200331-140 rather than Austroads Figure 8.1.
It is not Main Roads preferred practice to use staggered pedestrian crossings as shown in Figure 8.2.
8.2.4 Kerb Ramps for Pedestrians
