Wheel Stops

Wheel stops may be provided where it is considered necessary to limit the travel of a vehicle into a parking space. Note they should be avoided in any situation where they may be in the path of pedestrians moving to or from parked vehicles, or crossing a car park for any other purpose.

Wheel Stops shall not obstruct accessible travel paths for people with disabilities.

All kerbs, wheel stops, low barriers and other obstructions that could be a tripping hazard to pedestrians shall be surfaced in a colour contrasting with their surroundings.

Wheel stops are typically used to:

    (i) limit kerb overhang which is inconvenient or hazardous for pedestrians.
    (ii) inhibit contact with an end barrier or high kerb.
    (iii) inhibit encroachment into an opposing parking space.

Wheel stops shall be:

    (i) between 90 and 100 mm in height, and
    (ii) 1650 ±50 mm in width.

Positioning of wheel stops:

Where reverse-in parking is unlikely, e.g. at 30, 45 and 60 degree angle parking modules with one-way aisles, or where occasional minor encroachment (up to about 400 mm) by a reverse-in vehicle can be tolerated, e.g. over a kerb, wheel stop positions shall be set at the front-in position.

If reverse-in parking is likely and encroachment over the end of the parking space cannot be tolerated, wheel stop positions shall be set at the rear-in position and all vehicles required to back in.

Bollards

Other protective devices shall be provided as necessary to protect parts of the building or other fixed objects or equipment from damage by vehicles. Such protection shall include devices to prevent vehicle encroachment into pedestrian ways, stairs, doorways, lifts and the like.

Appropriately located bollards are suitable for these purposes. Protective devices shall be clearly visible to drivers when in their normal driving position.

NOTE: Design impact forces are given in AS/NZS 1170.1.


Other Barriers

Barriers shall be constructed to prevent vehicles from running over the edge of a raised platform or deck of a multi-storey car park including the perimeter of all decks above ground level.

They are required wherever the drop from the edge of the deck to a lower level exceeds 600 mm. At drops between 150 mm and 600 mm, wheel stops shall be provided.

Barriers shall comply with the following requirements:

(i) They shall be designed structurally for the loading requirements of AS/NZS 1170.1.

(ii) If at the end of a parking space, they shall be at least 1.3 m high so that drivers of cars backing into the space can see the barrier above the rear of the car. NOTE: The upper portion of such a barrier may be a light structure provided for sighting purposes only.

(iii) They shall not be made from brickwork, unreinforced concrete or other materials likely to shatter on impact.
