摘要
依据效用最大化原则,以出行成本比、出行时间比、出行目的、出行消费、个人收入等因素为效用变量,结合武汉市2018年居民出行调查数据,构建私家车与公共交通出行选择的效用函数,并将两者的出行时间比划分为1:1、1:2、1:4三种情形,借助卡方检验分析居民出行时间与出行方式之间的因素内在联系。研究结果表明居民出行方式研究对解决现有市政交通系统存在问题,提高城市公共交通系统出行效率具有重要意义,适度提高出行成本比可以降低私家车使用频率,有效缓解交通拥堵。
According to the principle of utility maximization,the travel cost ratio,travel time ratio,travel purpose,travel consumption,personal income and other factors are used as utility variables,combined with Wuhan residents'trip survey data in 2018,to construct a utility function for private car and public transportation travel selection,And divide the travel time ratio of the two into three situations:1:1,1:2,1:4,and use chi-square test to analyze the internal relationship between the factors of residents'travel time and travel mode.The research results show that the study of residents'travel mode is of great significance to solve the problems of the existing municipal transportation system and improve the travel efficiency of the urban public transport system.Properly increasing the travel cost ratio can reduce the frequency of private car use and effectively alleviate traffic congestion.
