基于动态重复博弈的车辆换道模型

在对车辆换道行为分析的基础上,提出了一种应用动态重复博弈原理建立车辆换道模型的方法,对每个阶段车辆的博弈过程以及车辆行为策略进行了描述,并利用速度期望的值作为车辆不同行为决策概率,在此基础上,考虑影响车辆速度期望的各个因素来对车辆速度期望的获得进行了分析。通过对不同交通流条件下实际调查的车辆换道次数与仿真值进行比较,表明了所提出模型的有效性。

Lane Changing Model Based on Discrete Dynamic Game

On the basis of analysis of lane changing action,a way of building model based on discrete dynamic game was put forward.Then the stage game process between two vehicles and action strategy of each vehicle were described,and the speed expectation of each vehicle was regarded as the probability for different strategies.Last, regarding all the factors which affect the speed expectation,the speed exception was achieved.By comparing the surveyed lane changing times with that of the simulation values under different traffic flows,the effectiveness of the model is validated.
