The recommended setback distance for a wombat crossing from a roundabout (as per the Austroads Guide to Road Design) is 6-10m. This distance allows:
- Adequate vehicle queuing space between the crossing and the roundabout entry/exit.
- Improved visibility for both drivers and pedestrians.
- Reduced risk of blocking circulating traffic, especially in single-lane roundabouts.
- Adequate signage will be installed so drivers anticipate pedestrian activity without abrupt stops.
The designs are dictated by Australian Standards and Austroads Guide to Road Designs with approvals and permits issued by the Department of Transport & Planning and endorsed by Transport Accident Commission.
