Abstract: In order to give priority to control emergency vehicle signals at intersections, a priority control method for emergency vehicle signals at intersections is proposed based on wireless communication technology. The setting method of vehicle detector and emergency vehicle detector is analysed, and the non-delay model of emergency vehicle passing through the intersection is established to solve the phase and green time problems of emergency vehicle. Combined with wireless communication technology, the determination process of priority signal of emergency vehicle under fixed cycle conditions is elaborated in detail. The experimental results show that the queuing time of the designed French ordinary cars is significantly shortened, the average number of stops can be ignored, and the average delay time is shorter than that of the traditional method. This provides theoretical and practical basis for further guaranteeing the implementation of urban emergency rescue green channel and enriching the content of urban emergency rescue decision support method.
