本文提出了一种具有多个用户类别的组合行程分配和分配模型，其中每种模式的出发地的行程产生和目的地的行程景点都是可用的。在该模型中，熵型（或重力型）出行分配子模型与多类用户交通网络的用户均衡分配问题相结合。原始的非对称链路成本函数可以通过“归一化”过程转换为对称形式，从而建立等效的凸数学规划模型。分别开发了基于 Frank-Wolfe 和 Evans 的两种不同算法，并报告了它们在测试网络上的计算结果。该模型适用于拥堵和多模式道路网络，其中所有交通的路段行驶时间相似。
This paper presents a combined trip distribution and assignment model with multiple user classes, in which the trip productions at origins and trip attractions at destinations for each mode are available. In this model, the entropy-type (or gravity-type) trip distribution submodel is incorporated with the user equilibrium assignment problem for multiclass-user transportation networks. The original unsymmetrical link cost functions can be converted to symmetric forms by a ‘normalization’ procedure, and hence an equivalent convex mathematical programming model is formulated. Two different algorithms based on the Frank-Wolfe's and Evans', respectively are developed and their computational results on test networks are reported. This model is appropriate to be used on congested and multi-modal road networks in which the link travel time is similar for all traffic.
