Abstract: In response to the problem of low traffic efficiency at intersections in the city due to the traditional rotation of traffic lights, this article proposes to rely on intersection camera image recognition technology and intelligently control the direction and duration of the intersection based on the dynamic data of vehicles queuing at each intersection. Considering that people want to queue as little as possible while not wanting their own queue length to be much longer than others' queue length, this article comprehensively considers minimizing the total queue length at intersections and minimizing the variance of queue length in each direction. The control strategy that minimizes the final result by weighting and summing the two factors is the optimal strategy. In order to compare with the alternate traffic strategy, this article uses computer generated simulation data based on field observations to calculate and compare, in order to achieve the optimal dynamic control strategy for intelligent traffic signals.
