Study on differential dynamic Stackelberg game model and calculating method by GA for traffic guidance strategy

Aiming at actual traffic travel guidance demand, the common information for gaming was analysed. The strategies of traffic management and road users were studied, and a differential Stackelberg game model which could describe the guidance strategies was constructed based on the established fuzzy model of road users. After two phases game character of traffic travel guidance were summarized, converse induction method to solving game process was brought out. The calculating method by genetic arithmetic (GA) to solve Stackelberg game model was devised. And the travel guidance scheme solved would achieve the aim of the individual user optimum based on system optimum. The analysis result for the example road-net shows that the game model and calculating method brought out in the paper would importantly conduce to produce the traffic guidance scheme for traffic guidance system from the aspect of theory and technology.
