Abstract

This study observed and recorded driver behavior at a variety of RTOR (right turn on red) locations and summarizes and reports the results. The study first determined which driver behaviors would be observed, and studied the following: conflicts (turning right on red); degree of stopping; condition of not turning on red; and vehicles turning right. Findings with regard to each of these areas are discussed. It was found that the majority of drivers who execute RTOR do so without conflicts imposed by pedestrians or cross-street traffic. Pedestrian conflicts are experienced infrequently (4.6% of all RTOR movements). However, the latter can create potential safety problems. It is noted that RTOR provides increased capacity and operational efficiency at a low cost, but the issues of law violations and limited sight distances need to be addressed in order to reduce the potential for safety problems.
