Study on Signal Warrant of Intersection Based on Traffic Efficiency

Abstract:

As an important index on evaluating intersection traffic efficiency, vehicle average delay played more and more roles on traffic prediction and evaluation modeling, this paper proposed an intersection signal warrant model using average delay which can evaluate traffic efficiency. According to compare the average delay of intersections before and after installing signal, average delay critical match model is established to show the warrant of signal setting. In this model, traffic volumes of major and minor approaches are main variables which are to argue whether the intersections need to be signalized, and several kinds of critical volume curves diagrams are given to show the warrant of different characteristics’ intersections.
