交通政策对主卫城间多模式交通选择行为的影响及系统效益测算

交通政策和管理措施的实施会对主卫城间多模式复合交通出行行为选择方式和系统整体效益产生影响，需要科学评估其影响程度，为城间交通模式的协调配置提供参考。在对城间交通模式及其出行行为特征进行分析的基础上，将基于随机效用理论的MNL模型和基于Logsun差异的效益测算方法相结合，针对城间4种典型的交通模式，通过构建基准情景和多种可能情景，测算了不同交通政策实施对城间交通出行选择的影响和出行者效益。结果表明，实施公交优先（减少乘客出行时间）对城间交通出行选择行为的影响较大，并具有较明显的系统经济效益，在协调城间交通模式配置时可优先考虑。

Influence of transportation policy on the multi-mode transportation choice behavior between megacity and satellite city and the system benefit estimation

Transport policy and management measures have an influence on muti-mode transportation choice behavior between megacity and satellite city and the system’s whole benefits, which makes it necessary to make a scientific evaluation of the influence and provide a reference for the coordinated configuration of the intercity transportation mode. Based on the analysis of intercity transportation mode and the characteristics of travel behavior, MNL on the basis of random utility theory and benefit estimation method on the basis of Logsum differences were combined together. According to the four typical intercity traffic patterns, the influence of the different transportation policies on the intercity travel choice and travelers’ benefits were estimated by constructing a baseline scenario and a variety of possible scenarios. The results show that the implementation of bus priority policy (to reduce passenger travel time) has a significant impact on intercity travelers’ behavior choice and achieves obvious system economic benefits, which should be given priority in the coordination of intercity transportation mode.
