PHOENIX – In order to increase safety and mobility in highway work zones, the Arizona Department of Transportation is studying a “smart work zone” at an existing I-40 bridge project located between Flagstaff and Winslow.
A smart work zone is a traffic management system that can be controlled remotely through computer networks, portable message boards and sensor technology to provide motorists with real-time traffic information as they approach construction work zones. This project utilizes a dynamic merge system, which is a specific type of smart work zone.
