A Speed Control Strategy at Signalized Intersection under Connected Vehicle Environment

In order to reduce the blocking of traffic flow of the signalized intersection on the urban road, for individual vehicles can interact the information with the roadside facilities and the intersection control system under the connected vehicle environment, a speed control strategy in the signalized intersection is proposed. This strategy considers driving comfort and environmental friendliness with the improvement of traffic efficiency. To verify the efficiency of the speed control model, the speed control simulation system embodying the characteristics of the connected vehicle environment in the signalized intersection is developed using the multi-agent technology, and a typical intersection is selected as an example, in which the travel time, fuel consumption and pollutant emissions under the traditional environment are compared with that of the connected vehicle environment when vehicles pass the intersection. The results show that when vehicles go through intersections, the average travel time is reduced by about 60% by the aid of the speed control strategy, with the fuel consumption reducing by about 40%. In addition, pollutant emissions are also reduced significantly.
