Right-turn-on-a-red traffic signal (RTOR) is a practice which has gained wider acceptance and use by the states in the last few years. However, there is still disagreement on whether, where, and how RTOR should be implemented. Accordingly, the objectives of this study were to determine whether permitting RTOR is desirable and to prepare guidelines for determining inclusion or exclusion of this movement. The study scope included field data collection and computer simulation analyses, accident analyses, driver and pedestrian attitude surveys, legal and law enforcement analyses, and a signing needs evaluation. The results of the various studies support the adoption of the generally permissive RTOR rule by all states. Significant benefits in the form of reduced delay, fuel consumption, and auto emissions can be realized without sacrificing safety.
