A Novel Signal Control Method for Offset Intersection

Offset intersections are common in urban areas. The special geographical characteristics of offset intersections include two T-legged intersections that tend to make the passing vehicles stop twice in a very short distance. This can result in severe travel time delay and low traffic service levels. In this monograph, the authors emphasize the importance of setting up a proper traffic control method to raise the discharge efficiency of the offset intersection. Based on an analysis of geographic characteristics and traffic characteristics of a specific kind of offset intersection, the authors propose a new kind of traffic control method. Simulation results on this model demonstrate that the discharge efficiency of the offset intersection is improved by the traffic control method. In addition, the average delay is significantly reduced. The authors discuss the implementation steps, the advantages, and the limitations of their proposed traffic control method.
