End-of-queue collisions are one of the biggest risks in roadwork traffic management zones, especially on high-speed roads. To help reduce these incidents, Main Roads WA has released an update to its fact sheet on avoiding end-of-queue collisions.
What’s New
-
Simplified method for predicting queue lengths.
-
Clearer guidance on sign spacing and warning layouts.
-
Greater focus on site conditions like speed, road curves, and visibility.
-
Procedures for monitoring and adjusting signage in real time.
-
Invitation for industry feedback before the guidance is finalised.
Key Takeaways
-
Assess traffic speed, sight distance, queue build-up, and vehicle mix when planning works.
-
Place “Prepare to Stop” signs at the right distance to give drivers plenty of warning.
-
Monitor queues during works and adjust signage as needed.
-
Avoid peak hours and use extra controls (like a second controller or VMS boards) in high-risk areas.
Making It Easier for You
To support these updates, we’ve created an End of Queue Calculator based on the new Main Roads method. This tool helps you quickly and accurately estimate queue lengths, ensuring your sites stay compliant and safe.
