摘　　要：传统连通可靠性对于路段的状态划分过于严格,只有中断或连通两种状态。为了能完全体现路网的动态特性,本文建立了一种新的连通可靠性的评价方法,将路网中路段的可靠度从0、1二值扩展到[0,1]区间。作者结合北京城市路网中快速路与主干道的实测数据,分析了基于交通流状况分析的连通可靠性评价方法,并在此基础上,进一步分析了该评价方法中的路段交通状态划分,提出了连通度指标以评价城市道路单元的连通性,最后分析了整个路网的连通可靠性。Traditional connectivity reliability is divided into two states, that is interrupt or connection. In order to fully reflect the dynamic characteristics of a road network, this paper established a new evaluation method for the connectivity reliability, the road network reliability was extended from O, 1 to [0, 1] interval. Soit will better reflect the real transport network, at scientific and reasonable for the evaluation of the result on the above analysis, reliabili propose analysi for the ty da assessment this of a the sofa same time, be more network. Based paper summarized the research status on the performance road network system at home and abroad. Based ta of the network in Beijing and the analysis of traffic flow, thi d a method of connectivity reliability evaluation, followed by the on the s paper further s of the traffic state division, the method proposed the connectivity indicators evaluation of a urban road connectivity unit
