| 摘 要： | 为防止路网交通拥堵的扩散,考虑路段状态指标饱和度和行程时间的影响,建立了基于合理路径集的路网分析模型.将非拥挤区域从内到外分为控制层、诱导控制层、诱导层和无关层4个层次,反映了路网状态的空间分布和潜在演化趋势.基于交通分配得到的流量,对本文的状态分析模型进行了数值验证,仿真结果表明:各层次路段在路网中的比例随流量的增大而变化,且拥堵区域呈现扩张趋势;高峰时段各层次路段的比例为20%、5%、10%、10%和56%;同层次中饱和度越大的路段对拥堵区域的影响越大.

| Abstract: | In order to prevent the propagation of traffic jam throughout the road network,a traffic network analysis model is built,which is based on reasonable routes taking into account both the degree of saturation and the travel time.The uncongested zone out of the central congestion layer is classified into four layers from inside to outside: control layer,guidance-and-control layer,guidance layer,and unrelated layer.These layers help reflectthe spatial distribution of network traffic states and the potential evo... |
