Abstract:

Aming at the problem of lower coordination efficiency level and the dimension disaster of traditional distributed adaptive traffic signal control, a model of urban regional traffic signal control system is established which is formulated as a local cooperation game of signalized intersections. On this basis, the learning algorithm based on the local information game exchange is proposed. It can adjust the control policy independently so that it can gradually learn the optimal traffic signal control policy. The performance evaluation index is constructed by weighting the average delay and parking times of the road network. The simulation experiment shows that the game-learning achieves better control effect and convergence compared with the actuated control and genetic algorithm in different traffic demand cases. It has better ability to manage and control overflow.
