Treating Potential Back-of-Queue Safety Hazards

This four-page resource focuses on the following key principles and solutions:

• Queuing Analysis is Critical: Work zone lane closures can quickly create queues that increase crash risk. Capacity and demand analysis tools help agencies predict and mitigate these impacts before construction begins.
• Proactive Safety Strategies: Recommended treatments include maintaining lane capacity where possible, adjusting taper lengths and sign spacing, deploying queue warning systems, and using law enforcement presence to alert drivers.
• Technology and Operations Solutions: Intelligent Transportation Systems (ITS), variable speed limit systems, and nighttime construction are among advanced strategies to reduce congestion and improve safety at the back of the queue.
