心理因素影响的公交方式选择行为模型

为解决已有城市公交方式选择行为模型无法定量描述心理因素对选择行为的影响,分析了计划行为理论在公交方式选择行为的适用性.基于态度、主观规范及知觉行为控制3个心理因素变量决定公交方式出行行为意向的理论框架,构建公交方式选择行为结构方程模型.确定模型中心理因素变量对应的具体测量变量,并提出模型的求解方法和参数检验标准.最后,将模型运用于重庆和成都的实例分析中,共回收有效问卷790份.计算结果表明,3个心理因素变量对重庆和成都公交出行方式选择行为意向解释度分别为72%和66%,其中知觉行为控制因素的影响最大,且心理因素变量间存在着相互作用关系.

Choice Behavior Model of Urban Public Transport Considered the Psychological Factors Affecting

In order to solve the problem that the existing choice behavior model of urban public transport can not describe the process of psychological factors affecting, the applicability of theory of planned behavior (TPB) in public transport mode choice is analyzed. Based on the theoretical framework of public transport choice behavior intention determined by residents' attitude, the subjective norm and perceived behavior control(PBC), structural equation model of public transport mode choice behavior is constructed. Then, specific variables corresponding to psychological variables in the model is determined, meanwhile, method of solving the model and parameter test standard are put forward. Finally, the model is applied to the analysis of typical city Chongqing and Chengdu, in China. And a total of 790 valid questionnaires are collected. The calculation results show that the degree interpretation of public transport choice intention by three psychological factors in Chongqing is 72% and Chengdu is 66% , and the greatest influenced by PBC. Moreover, there is interaction relationship between psychological factors.
