【摘要】：为了能够深入分析路网交通拥堵动态演进过程,为交通拥堵治理提供决策分析工具,提出了一个基于复杂网络的路网拥堵评估仿真模型。通过将路段阻抗概念引入复杂网络理论,实现了路网拓扑模型和流量模型的结合;此外,还提出了虚拟测试车辆遍历的路网通行能力评估方法,对不同路网条件下的道路通行能力进行评估。最后在PC系统上实现了完整的路网拥堵评估仿真系统,并利用该系统对拥堵路段数量、交通流量和路网拓扑结构等因素对路网通行能力的影响进行了仿真分析。仿真实验结果与经典交通理论分析结果一致,并能反映更多的动态过程信息,表明该模型能够准确有效地进行交通路网拥堵评估,可以为相应的交通拥堵管理决策提供依据。
[Abstract]:In order to analyze the dynamic evolution of road network traffic congestion and provide a decision analysis tool for traffic congestion management, a simulation model of road network congestion evaluation based on complex network is proposed. By introducing the concept of section impedance into the theory of complex network, the combination of network topology model and flow model is realized, in addition, the evaluation method of road network capacity based on virtual test vehicle traversing is proposed. The road capacity under different road network conditions is evaluated. Finally, a complete network congestion assessment simulation system is implemented on PC system, and the influence of the number of congested road sections, traffic flow and network topology on road network capacity is analyzed by using the system. The simulation results are consistent with the classical traffic theory analysis results and can reflect more dynamic process information. It shows that the model can accurately and effectively evaluate the traffic network congestion and provide the basis for the corresponding traffic congestion management decisions.
