摘要
在用户平衡(UE)和系统最优前提下,借助于Share需求模型,提出了基于四阶段法的交通需求预测组合模型,克服了传统四阶段法中由于各个阶段相对分割和独立,造成的人力物力耗费巨大,预测工作量大的弊端。对于交通预测的实际工作具有指导性作用。
On the basis of UE and SO, a combination model of traffic demand forecasting for four-stage method was presented based on Share demand model. The proposed method has a smaller consumption of computation and manpower as well as material resources than the traditional method and less mutual division and independence between each other. Thus, it overcomes the shortcomings in four-stage method. It helps to guide the traffic demand forecasting.
