摘要
组合模型是将传统的四阶段交通需求预测步骤中的两个或多个步骤组合起来 ,建立新的模型 .文中在比较常用的组合模型的基础上 ,提出了交通分布与交通分配组合模型 ,将交通分布中的重力模型和分配中的用户平衡模型组合起来建立一个新的熵模型 ,模型满足 UE平衡条件 .文中还介绍了该模型在软件 Trans CAD中的应用 。
In the process of traffic demand forecasting, combined model is a new one that is derived from the traditional 'four step traffic demand forecast model'. On the basis of introduction of the combined model that are often used, the article explicitly explains the combined model of traffic distribution and traffic assignment.The model is also an entropy model and satisfies the user equilibrium. At last the article introduces the application of the model in the software TransCAD. The conclusion points out the combined model's advantage and shortcoming.
