A Vehicle Passing Model in Non-signalized Intersections based on Non-cooperative Game Theory

Considering that under normal circumstances, there will be a lot of vehicles running at a non-signalized intersection, and the vehicles don't have intentions to cooperate. A vehicle passing model at non-signalized intersection for single vehicle is proposed in this paper. Based on game theory, each vehicle would construct its own game with different players. The profit function consists of safety, rapidity, comfort indicators, where the safety indicator is newly defined in this paper to conquer the uncertainty about whether a collision actually occurs. Nash equilibrium method is used to predict other players' decisions and obtain the optimal strategy. Finally, the simulation results are given, which prove the effectiveness and practicability of the model.
