分离式公交专用道的交通均衡模型

Traffic Equilibrium Model for Offline Transit Exclusive Roads

摘要: 本文提出一种新的分离式公交专用道的交通均衡模型。交通网络上同时存在公交出行方式和私家车出行方式，并且公交车辆在指定的专用道上运行。由于出行者对不同交通方式出行成本的估计是不精确的、随机的，因此采用随机选择模型来描述交通方式选择过程。与交通均衡条件等价的变分不等式问题在文中列出，并给出了相应的连续平均法算法。算例表明模型和算法有效。

Abstract: A novel traffic equilibrium model considering offline transit exclusive roads is proposed in the paper. Both transit vehicles and private cars exist in the network, and transit vehicles only oper-ate in the exclusive links. Since travelers have inaccurate and uncertain estimation on the travel costs, discrete route choice model is used to describe the users’ travel behavior. The user equili-brium equivalent variational inequality model is formulated, and the method of successive aver-age (MSA) is proposed to solve the model. The numerical example illustrates that the model and the algorithm are effective.
