Dynamic user optimal assignment and signal control based on the Stackelberg game
基于Stackelberg博弈的动态用户最优配流和信号控制

The combined dynamic user optimal assignment and signal control are studied.First,based on the idea that traffic flow is assigned on the proper road-net by the traffic assignment and the flow is adapted by the control system,a Stackelberg game model of traffic assignment and signal control is proposed.The upper-level of the model is dynamic user optimal assignment,and the lower-level is the signal optimization.Then,the discretization in time and a simulated annealing algorithm are used to obtain optimal strategies.Finally,a simulation is carried on a simple traffic network and numerical results demonstrate the effectiveness of the proposed approach.
