Abstract:

There is a lack of quantitative analysis on the interaction between public transit travel choice behavior, environmental concern, and habit. To solve this problem, three models were established based on the theory of planning behavior (TPB) and the theory of behavior driven by habit. The established models were a basic structure equation model A of public transit travel choice behavior based on traditional TPB, an extended model B incorporating environmental concern, and an extended model C incorporating both environmental concern and habit. The quantitative relationship between the factors influencing public transit travel choice behavior was analyzed through comparison. Finally, the models were applied to case analysis in Chongqing, and 401 valid questionnaires were collected. The results indicated that the model C has the best fitness and interpretability, followed by the model B. Moreover, the environmental concern and habit have effects on public transit travel choice behavior, but the effects are lower than that of travel behavior intention and perceived behavior control.

Key words: urban traffic, travel choice, environmental concern, theory of planning behavior, mediator effect

摘要：

为解决公交出行选择行为、环保意识与出行习惯之间缺少定量分析交互作用的问题，基于计划行为理论(TPB)，结合习惯驱动行为理论，构建公交出行选择行为结构方程基本模型A，增加环保意识的扩展模型B，以及涵盖环保意识和出行习惯的扩展模型C，对比分析公交出行选择行为各影响因素之间的定量关系.最后，将模型运用于重庆市实例分析，共回收有效问卷401份.结果表明：模型C的拟合效果及解释性最好，模型B其次；环保意识、出行习惯均对公交出行方式选择行为存在影响，但影响程度低于行为意向和知觉行为控制.
