摘要
为合理有效地计算城市路网可靠性,首先在分析出行者路径选择行为特性的基础上,将OD路网划分为主通路和连接路段,然后提出了主通路的判定方法和主通路可靠性的计算方法,并引入修正系数反映连接路段对主通路可靠性的影响,进而可以计算城市路网可靠性。最后,用一算例验证了方法的有效性,分析表明基于层次网络的可靠性计算方法准确性高、速度快。
In order to calculate the reliability of urban road network reasonably and effectively,OD road network was divided into main roads and connection roads on the basis of analysis to the characteristics of path choice firstly.Then,determination method of main roads and computation method of the reliability were proposed,and modified coefficient was used to reflect the effect of connection roads on the reliability of main roads,and then the urban road network reliability can be computed.At last,a numerical exam...
