共享交通下的城市居民中长距离出行方式演化博弈

    Evolutionary Game of Residents' Middle and Long Distance Trip Mode Under Sharing Traffic

    • 摘要: 针对引入共享交通以解决城市居民中长距离出行可达性问题,采用演化博弈理论,从收益矩阵、邻居网络结构、策略转换规则3个方面建立考虑出行者异质特性和城市交通运行状态的演化博弈模型,使用多智能体仿真方法研究引入共享交通后的城市居民中长距离出行方式演化过程,分析相关参数对于演化过程的影响.结果表明:效用感知水平能够描述出行者的异质特性;平峰时段的出行者受接驳激励效用影响最大;提高外部成本能使早、晚高峰时段的出行者出行选择更加稳定;接驳激励效用和外部成本的提高都能够促使更多的出行者使用公共交通出行,由于存在非理性出行者,其对于公共交通出行比例的提升也是有限的.因此,在制定城市交通政策时需要考虑激励效率,并不断完善城市交通基础设施,以保证相关政策起到激励和管制作用.

       

      Abstract: To solve the issue of residents' travel accessibility of middle and long distances by introducing sharing traffic, an evolutionary game model was established considering the heterogeneous characteristics of travellers and the state of urban traffic from three aspects: income matrix, neighbor network structure and policy transformation rules. The method of multi-agent simulation was used to study the evolution process of residents' middle and long distance trip mode after the introduction of sharing traffic, and the influence of relevant parameters on the evolution process was analyzed. Results show that the utility perception level can be used to describe the heterogeneous characteristics of the travellers; the travellers are mostly affected by the connection incentive utility in ordinary period; the increase of the external cost can make the traveller's choice in the morning and evening rush-hour more stable; the increase in connection incentive utility and external cost can encourage more travellers to use public transportation, however, the increase in the proportion of public transport is limited due to the presence of irrational travellers. Therefore, it is necessary to consider incentive efficiency when formulating urban transportation policies, and continuously improve urban transportation infrastructure to ensure that relevant policies play an incentive and regulatory role.
