摘要:

研究城市群综合客运交通网络脆弱性有助于保障城际出行的运输效率。为了更符合实际情况,采用多层复杂网络理论建立城市群综合客运网络,考虑城市交通换乘因素,利用实际客流标定站点负载及容量,构建网络级联失效动态模型,并用多智能体模型模拟实际客流,通过迪杰斯特拉算法寻找最短路径,并提出时空维度的脆弱性评价指标。实例动态仿真采用呼包鄂榆城市群,结果表明:大部分火车站受到攻击后对网络的影响范围及时间较大;站点受到攻击后对网络的影响范围与持续时间没有明显关系。

Abstract:

Research on vulnerability of comprehensive passenger transportation network in urban agglomerations helps to ensure the transportation efficiency of intercity travel. A comprehensive passenger transport network model of urban agglomeration is built based on multi-layer complex network theory. Urban transportation transfer factors are considered, actual passenger flow is used to calibrate the station load and capacity and a dynamic model of network cascading failure is constructed. Multi-agents are used to simulate the actual passenger flow, Dijkstra algorithm is used to find the shortest path, and two time-dimensional vulnerability evaluation indicators are proposed. MATLAB is used to carry out the dynamic simulation of Hubao-Eyu urban agglomeration. The results show that most train stations have obvious range and time, impact on the network after being attacked, but the duration is not significantly different from the bus stations. The impact on the network of different sites being attacked has no obvious relationship with the duration.

Key words: urban agglomeration transport, passenger traffic network, multi-agent, vulnerability, dynamic simulation
