WHAT IS RED LIGHT RUNNING? A CASE STUDY FROM RHODE ISLAND

The goal of the project was to determine the severity of red light running in Rhode Island. Central to the data capture process was the use of specialized portable video camera set-ups, which captured views of every approach with one camera. Signal phasing was captured simultaneously by linking to the signal controller. The audio data were transmitted using wireless technology. Twenty intersections were viewed throughout the state, ranging from rural to urban settings. For the twenty intersections viewed, there were a total of 8,587 violations observed over a period of 1359 hours. This amounts to an average RLR violation rate of 6.3 violations/hr. For the individual intersections, the violation rates ranged from 1.2 to 15.0 per hour. The violations were also specified by the time that had elapsed in the red phase. From analysis of the data, there are intersections in Rhode Island where RLR is a problem. A model was developed to prioritize intersections based on a Composite Intersection Index (CII), where the highest score indicated the most problematic intersection. The CII was based on a comprehensive set of variables including the following: (1) entering ADT (1000s of vehicles); (2) number of lanes entering the intersection; (3) RLR violation rate; (4) proportion of violations occurring after 1 second; (5) number of phases; and the (6) average approach speed (based on approach speed limits).
