基于演化博弈论的汽车共享与私家车博弈研究

汽车共享能够显著缓解交通拥堵、降低城市交通污染.由于汽车共享能够部分代替私家车出行,汽车共享方式的引入对居民出行行为选择具有重要意义.基于演化博弈论,分析了汽车共享引入后与私家车的博弈过程.以城市居民出行选择行为为出发点,分析汽车共享和私家车出行方式的特点,考虑汽车共享服务水平随服务人数变化因素、政府参与管理因素,建立汽车共享和私家车的演化博弈模型.根据动力学相关知识,分析模型参数,得出各个平衡点稳定的条件.通过分析系统演化稳定状态,为汽车共享出行方式的推广和政府相关政策制定提供理论支撑. 

A Game Analysis Between Carsharing and Private Cars Based on Evolutionary Game Theory

Carsharing can effectively relieve traffic congestion and pollution in cities.It is considered as an alternative trip mode to private cars, and has significant effects on choosing behaviors of travelers.Based on Evolutionary Game Theory, a game process of traveler's trip mode between carsharing and private cars is analyzed.Based on choosing behavior of travelers, an evolution game model is established.This model focuses on different features of trip mode by carsharing and private cars, service level of carsharing changes with number of travelers, and government participation in management.Stable conditions of equilibrium points are obtained under different model parameters based on dynamics.The analysis results of evolutionary stable state may provide support for promotion of carsharing and setting of government policy.
