城市OD区间道路总容量的模型研究

A Model of the General Capacity Between OD Region Road in City

定义了城市OD间路网总容量，根据交通流平衡分配原理，以路径走行时间与路径上交通流量之间的关系为基础，建立了利用路段观测交通量和OD区路径走行时间推算城市OD间道路网容量的数学模型。证明了该模型存在唯一的解，通过算例对该模型进行了验证，表明模型能逼近实际。

City traffic is the base of society exists and growth, so the evaluation of the road network traffic capacity is a notable problem needing solved. However, the estimation of OD Road-network traffic capacity is very important to the problem of city. This paper defines city OD Road -network traffic capacity and puts forward a model that can calculate the capacity of ODfrom a section of highway traffic and the time in ODes route. The model surmounts the defect of other models from a strict proof about the root. Application of the model indicates that the model is useful and correct.
