针对水陆混合运输网络,提出新的交通量分配方法.借助时空拓展转换以及独特的路段阻抗函数结构,将已知混合运输网络转换为标准运输网络;基于标准网络构建用于计算用户平衡状态的交通量分配模型;利用Frank-Wolf法进行求解,获得用户平衡状态下交通量在混合运输网络上的分布形态.该文旨在为在固定运输路线上由大型运载工具做周期性运营所形成的运输网络提供一种符合实际的用户平衡交通量分配方法.
Aiming at the mixed transport network of water and land, a new traffic distribution method is proposed, which converts the known mixed transport network into a standard transport network with the help of space-time expansion transformation and a unique structure of road impedance function, and builds a traffic network based on standard network to calculate user equilibrium Volume distribution model, the use of Frank-Wolf method to solve, access to the user equilibrium traffic distribution in the mixed transport network morphology.This paper aims for the fixed transport routes carried out by the periodic operation of large carriers formed by the transport The network provides a realistic method of user-balanced traffic distribution.
