Evaluation of the Intersection Confirmation Light System to Reduce Red Light Running Violations at Freeway Ramp Intersections

Red light running (RLR) crashes are a serious safety concern at signalized intersections. In 2009 the Federal Highway Administration (FHWA) reported that 676 fatalities (FHWA, 2011) and 130,000 injuries were due to red light running crashes in the United States (IIHS, 2011). The Insurance Institute for Highway Safety (IIHS) reported that in 2007 over half of the red lights running fatalities were passengers of the violating vehicle, both passengers and the driver of the vehicle that was collided into, or pedestrians within the intersection (IIHS, 2007). Many communities have installed automated enforcement as a way to enforce red light violations at high-crash intersections. In 2011, it was estimated that over 538 communities had installed automated enforcement (IIHS, 2011). However, automated enforcement may not be practical for an intersection or cannot be implemented due to state legislation. Many communities have implemented low-cost countermeasures at intersections including intersection confirmation lights to alert the driver of the changing light and/or aid law enforcement officials in capturing violators.
