A multi intersections signal coordinate control method based on game theory

In this paper, the two-person static game model was applied in multi intersections coordinate control problem. A method of choosing the final solution from pure strategy Nash equilibrium, mixed strategy Nash equilibrium, Pareto efficiency solution and Pareto improvement solution of Nash equilibrium was proposed. And, the single intersection coordination was combined with multi intersections coordination. Furthermore, different priorities were set for different intersections in coordination rule. The simulation showed that by adopting such method in road network, the average delay time of vehicles can be reduced up to 71.34% effectively, and the method can also be adapted to single intersection and road network in different traffic flow.
