摘要/Abstract

摘要： 为有效服务于灾变事件下高速公路通道路网的路径诱导和控制管理，提出了路网中管理单元的划分方法;针对未发生灾变事件的管理单元，考虑管理单元长度、平均车速以及实时交通密度的影响，建立行程时间特性函数;结合发生灾变事件时管理单元的排队－消散特征，利用流量、密度关系模型确定事件持续时间和消散时刻，构建基于波动理论的事发管理单元行程时间模型;以实时安全可靠度作为路阻函数对模型进行了修正，最后通过实例验证了计算模型的有效性．

Abstract: In order to effectively serve the route guidance and control management of the expressway corridor network in disastrous events，a method to divide the management unit of road networks is put forward． For the management unit with no disastrous events involved，a travel time characteristic function is established by taking into account the influences of the management unit length，the average speed and the real-time traffic density． By combining the queuing and dissipating characteristics of the management units involving disastrous events and by using the flow and density relationship model，the duration time and dissipation time of incidents are determined，and a travel time calculation model of incident management units is constructed based on the wave theory． Then，the proposed model is modified by taking the real-time safety reliability as a road resistance function． Finally，the effectiveness of the constructed model is verified by an example．

Key words: disastrous event, freeway corridor network, management unit, travel time, wave analysis
