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 characteristic of urban multimodal transport system was fully analyzed and then based on graph theory,a hierarchical network was proposed to describe the system. Simultaneously, the complex travelers' choice behaviors including traffic mode choice and route choice were analyzed in hierarchical network and based on the analysis of travel demand, the generalized cost functions and the link impedance functions were formulated while mutual interferences of vehicle flow with different modes were considered. Based on it,a variational inequality model of equilibrium assignment for urban multimodal traffic network was proposed. The solution algorithm was also presented. Finally,a numerical example was used to illustrate the validity of model and algorithm. Results show that the proposed model and algorithm are effective |
