基于演化博弈的公共交通、共享汽车与私家车的博弈分析

出行者的选择行为分析是交通系统中的一项重要内容,随着城市的发展,交通出行方式大体分为三大类:公共交通出行、辅助公共交通出行和私人交通出行。本文在以往的研究基础上,采用演化博弈的方法研究公共交通、共享汽车以及私家车三者之间的博弈关系,模拟出行者的选择行为,分析博弈均衡点稳定性及参数条件。通过模型仿真实验,演化结果中各项比例大小取决于各项收益、补贴、损失以及额外收益,要增加公共交通的配套设施,增收拥堵费以及增加对共享汽车的补贴及配套服务。

A Game Analysis Among Public transport,Shared cars andPrivate Cars Based on Evolutionary Game Theory

Traveler choice behavior analysis is an important part of the transport system. With the development of the city, the mode of travel can be divided into three categories: public transport, auxiliary public transport and private transport.On the basis of previous studies, we use the evolutionary game method to study the game relationship among public transport, shared cars and private cars, simulate travelers’ choice behavior, and analyze the stability of equilibrium point and parameter conditions .Through the model simulation experiment, we get the result that the proportion of the evolution results depends on the benefits, subsidies, losses and additional benefits. It is necessary to increase public transport facilities, congestion charges and subsidies for shared cars and ancillary services.
