城市交通网络广义容量应用研究——以南京市为例

The research on the Application of Urban Transportation Network General Capacity

结合南京市交通网络的实际调查分析,本文对城市道路网广义容量算法的实际应用作了探讨,研究了算法中提出的城市道路网有效营运面积、有效营运时间、交通个体时空消耗以及有关各项参数的确定方法;同时,借用“时空消耗”概念,提出了城市公交线网总体容量算法模型;对南京市道路网、公交线网容量作了具体计算。文中提出的算法及有关参数可供其它城市参考。

In this paper, the application of the algorithm of urban transportation network general capacity (UTNGC) is studied, combining with the practical investigation and analysis for the transportation network of Nanjing. The method to determine the road available area, the road available time , the time-space consumption (TSC) of the travelling individuals and each related factor is explored. Similarly following the concept of TSC, the model of overall capacity of public transit networks is worked out. These alg...
