摘要
为解决现有居民公交方式选择行为模型中仅考虑可直接观测的显变量,尚未涉及对选择结果具有一定影响的不可直接观测的潜变量的问题,本文从潜变量与显变量角度,构建了公交方式选择行为结构方程模型.分析了各种影响因素之间的定量关系,以及对选择结果的影响作用大小,并依据出行者人格特质进行了分群行为特性研究.最后,将模型运用于成都公交出行实例分析中.结果表明:知觉价值对选择结果具有显著影响,可解释出行行为意向的62%信息,服务品质对知觉价值的影响高于票价合理性,且不同群体的选择行为特征存在一定差异.
To solve the existing mode choice behavior model of urban public transport considered only the observable variables, but do not relate to the unobserved latent variables which affect travel choices. And a structural equation model（SEM） of urban public transport mode choice behavior is built based on latent variables and observable variables. The quantitative relationship between various influencing factors and the effect to choice results are analyzed. With traveler personality traits, behavior characteristics of different groups are studied. Finally, the model is used in the Chengdu example analysis. It is pointed that the perceived value has a significant influence on choice results and can explain 62% of the travel behavioral intention. The service quality effect on perceived value is bigger than the price rationality. Choice behavior characteristics of different groups exist certain difference.
