Integrating Platoon-Priority Signal Control with Advance Warning Flashers

Status:  Complete
Report Date:  08/05/2009


Investigators developed an integrated signal control system that uses platoon priority and advanced warning flashers to increase the efficiency of high-speed isolated intersections. Simulations on data collected at a high-speed intersection found that the new system reduced delays and stops on the major approach by more than 50 percent, with an overall reduction in intersection delays and stops of 20 percent.
