基于SEM的运输通道出行方式选择决策机理研究

Decision-making Mechanism of Mode Choice in Transportation Corridor Based on SEM

为了描述和解释运输通道内客运出行方式的选择行为,从出行产生的内在机理入手,探讨出行者潜在心理因素对出行活动的影响。通过分析出行者出行的全过程,构建了出行决策的过程模型,概括出影响出行方式选择的因素,并运用结构方程模型(SEM)分析各项潜在影响因素对出行结果的作用大小。最后,以成渝运输通道内三种出行方式为例,验证了各影响因素对出行选择行为的作用机理。

In order to describe and explain the passenger travel mode choice behavior in a transport corridor, study of the mechanism of trips explored the impact of potential psychological factors on travel activities. By analyzing the whole process of the passenger travel, the paper constructed a travel decision-making process model, summarized the factors that affected the travel mode choice, and used the structural equation model to analyze the impact of various unobservable factors on the trip results. Finally, three travel modes in Cheng-Yu transport corridor were discussed to verify the mechanism of the factors on the travel choice behavior.
