Red-light violations at traffic signals are a major contributor to crashes and fatalities. Right-angle type crashes typically account for the most serious of these collisions, and most of them are caused by vehicles running red lights. This research will explore technology that could be used to warn drivers when they are about to run a red light.
“Intersections controlled by traffic signal systems in urban and suburban areas generate a significant volume of serious crashes because of angle-type crashes that are the result of red light running,” said Victor Lund, traffic engineer, St. Louis County. “Reducing red light running is a key strategy for Minnesota’s Toward Zero Deaths efforts.”
Objective
The goal of this project is to develop a red-light running warning system (RLRWS) and demonstrate it on the TH-55 connected corridor. The team will first develop and test the RLRWS in simulation in a laboratory setting. They will use dedicated short-range communications receivers with GPS chips to receive Signal Phase and Timing (SPaT) information, which will be processed in real time on a laptop computer with warnings displayed when appropriate. In the second phase, the technology will be tested on a research vehicle driving through a signalized intersection equipped with the appropriate radio equipment that will broadcast its signal phasing.
