摘要: 考虑交通出行需求和路网拓扑结构,研究了环形放射状路网上的交通拥堵特性。基于国内7个城市的出租车乘客OD数据分析,研究了出租车用户群体出行距离分布特性,建立了一种基于OD分布的交通需求生成普适性模型。在此基础上,研究了特定需求分布下规则网格状和环形放射状两种典型路网结构的交通拥堵特性。结果表明在满足特定OD直线距离分布的交通需求下,环形放射状路网拓扑结构能有效减少网络拥堵时间,节约交通出行成本。

Abstract: In this study, the traffic congestion of the ring-radial road network is investigated considering the traffic demand and road network topology. Based on the OD data analysis of taxi passengers from several cities in China, the travel distance distribution characteristics of the taxi users are studied; further, a universal traffic demand generation model is established based on the OD distribution. Thus, the traffic congestion in case of two typical traffic network structures, i.e., the regular grid and ring-radial road networks, are studied under the specified demand distributions. The results denote that the ring-radial road network topology can effectively reduce the network congestion time and reduce the transportation cost under the traffic demand that satisfies the specific OD Euclidean distance distribution.

Key words: traffic network equilibrium assignment, traffic demand distribution;topological structure;traffic congestion
