分析了城市多模式交通系统的结构特征,基于图论提出了一种分层网络结构来描述该系统,进而研究了出行者在多模式交通网络中的复杂选择行为(包括交通模式选择和路径选择);同时考虑了不同交通模式的道路流量之间的相互干扰,基于交通需求构造了城市多模式交通网络的广义费用函数和路段阻抗函数;在此基础上,提出了城市多模式交通网络平衡配流的变分不等式模型,并设计了求解算法;最后,用一个简单算例对模型及算法的有效性进行了验证。结果表明:提出的模型及算法是有效的。
The structural characteristics of urban multimodal transport system are analyzed. A hierarchical network structure is proposed based on graph theory to describe the system, and then the complicated choice behavior of travelers in multimodal transport network is studied (including traffic mode selection and route selection Based on the traffic demand, the generalized cost function and the link impedance function of urban multi-modal transport network are constructed. Based on this, the paper proposes the multi-modal transport network traffic dispatch The variational inequality model is designed and the algorithm is designed. Finally, a simple example is used to verify the validity of the model and the algorithm. The results show that the proposed model and algorithm are effective.
