上海市高速公路网多路径条件下驾驶员路径选择研究

Study on Driver Routing Preference in Shanghai Looped Expressway Network

为解决上海市联网收费系统中的多义性路径问题,采用陈述偏好调查法(SP)对路网中涉及多义性径的主要大流量OD对之间驾驶员路径选择进行调查,分析影响驾驶员路径选择的因素,总结上海市高速公路网中驾驶员路径选择特征和规律。研究结果发现,在常态交通条件下,运输总费用因素对驾驶员路径选择最为敏感,而特定交通事件(如道路维修或设置指路标志等)将对车辆路径选择产生根本性的影响。本研究可为高速公路网多义性路径问题研究提供新的思路和方法。

The formation of loops in Shanghai expressway networks brings about multi-routes between many pairs of entrances and exits, which raises the problem of how to allocate the toll gate to relevant roads.This study is to find out the main factors influencing the drivers' routes choice in Shanghai looped expressway network and to help understand the regular patterns of drivers' routes preference. A survey method of stated preference(SP) is used for investigating the drivers' routes between given entrances and exits in Shanghai expressway network.The results can provide a basic rule in traffic assignment in looped Shanghai expressway network,as well as in other similar expressway networks.
