Treating Potential “Back-of-Queue” Safety Hazards (presentation)Abstract:
The purpose of this document is to highlight strategies that can help reduce the work zone congestion that increases back-of-queue crash risk. Studies have shown that rear-end crashes in the advance warning area for a work zone are the most common type of work zone crash. Analysis of work zone impacts can help agencies design the appropriate mitigation techniques. Additionally, proper temporary traffic control and the use of congestion mitigating strategies and techniques will help manage the queuing associated with work zones.
– What are the hazards associated with queuing caused by work zones?
– What steps can be used to quantify work zone impacts?
– How do I determine when and where queues are likely to occur?
– What strategies that can mitigate potential back-of-queue hazards?
Planners, designers, construction engineers, and inspectors.
