In order to determine the necessity for the installation of a traffic signal at an intersection, a comprehensive investigation of both the traffic conditions and the physical characteristics of the location is required. Such traffic related factors as vehicular volumes, headways, turning movements, travel speeds and such physical factors as number and configuration of lanes, channelization, sight distance restrictions, and vicinity of other signals influence the performance of the intersection. The purpose of the study was to evaluate the significance of the right turn factor with respect to a common measure of intersection performance--average vehicular delay. The eventual goal will be to use one of the approaches to develop a comprehensive set of numerical guidelines for the treatment of right turns.
