Abstract:

In order to solve the problem that it lacks of quantitative consideration of the urban internal travel influence in passenger choice model in regional transportation, the whole process of regional travel is divided into three stages from the whole trip chain point. Then it is distinguished that the common and different influencing factors between regional and urban internal travel. The concept of inclusive values is proposed which is used to describe the comprehensive effect of urban internal travel to the choice of regional travel mode. The regional travel choice model, considering the urban internal travel function, is constructed based on the NL model. The characteristic variables are defined, and the parameters are determined by using NLOGIT software. Finally, Chengdu- Chongqing transport channel as a case to apply the proposed model, and 524 valid questionnaires are collected. The results show that urban internal travel is mainly affected by travel time, costs and transfer, and the superior ratio of the propose model is increased by 0.145 than the traditional model. Meanwhile, the interpretation and accuracy is improved.

摘要：

为解决区域客运方式选择模型中缺少定量考虑市内出行影响的问题，从完整 出行链的角度，将区域出行全过程划分为三阶段，区分了区域与市内出行的共性及差异 性影响因素.提出包容值的概念，用于描述市内出行对区域出行方式选择影响的综合效 用.基于NL模型构建涵盖市内出行作用的区域出行方式选择行为模型，对模型的特性变 量进行具体定义，运用NLOGIT软件对模型进行参数标定.最后，将模型应用于成渝通道 实例分析中，共回收有效问卷924 份.计算结果表明：市内出行主要受出行时耗、费用及是 否换乘3 个变量影响，考虑了市内出行包容值的改进模型优度比较传统模型提高了 0.145，显示模型解释度和精确性有一定提升.
