GUIDELINES FOR SELECTING TRAFFIC SIGNAL CONTROL AT INDIVIDUAL INTERSECTIONS

An NCHRP Project 3-27 comprehensive guidelines were developed to help traffic engineers evaluate the costs and benefits of various control alternatives while taking roadway and traffic conditions into account. Although the emphasis was on traffic control at isolated intersections, adjacent intersections were considered in regard to the need for coordinated operation. This digest discusses the approach used and gives the findings and conclusions of the study. Graphs are presented giving a comparison of controller performance in terms of delay per vehicle and percent stops per vehicle.
