Research on the Connectivity Reliability of Transport Networks

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 0,1 to interval.So it will better reflect the real transport network,at the same time,be more scientific and reasonable for the evaluation of the results of a road network.Based on the above analysis,this paper summarized the research status on the performance reliability assessment of a road network system at home and abroad.Based on the combined data of the network in Beijing and the analysis of traffic flow,this paper proposed a method of connectivity reliability evaluation,followed by the further analysis of the traffic state division,the method proposed the connectivity indicators for the evaluation of a urban road connectivity unit.
