考虑互补效率的城市群综合客运网络可靠性研究
Reliability Assessment of Comprehensive Passenger Transport Networks in Urban Agglomerations Considering Complementary Efficiency
分析城市群客运网络中不同交通模式在面对攻击时互补效应对网络可靠性的影响。首先,采用复杂网络理论中的Space L建模方法构建综合客运网络模型,考虑时间与流量标定网络边权与点权。然后,提出考虑时间加权的网络相对时间效率与流量加权的最大连通子图的相对大小作为网络可靠性评价指标。引入引力模型计算节点失效之后其他网络节点产生的互补功能,并计算动态互补强度来量化交通网络间的互补作用。最后,以呼包鄂乌城市群为实例进行仿真研究。结果表明,考虑互补效应的网络在面对攻击时能够保持更高的性能水平;普铁网络在节点攻击中断后能够从其他网络中获得较强的互补网络相对时间效率,约为56.76%;高铁网络在节点攻击中断后能够从其他网络中获得较强的互补最大连通子图的相对大小,约为35.17%。
To analyze the influence of the complementary effects among different transportation modes on network reliability facing attacks in the passenger transportation network of urban agglomerations, a comprehensive passenger transport network model is constructed using the Space L method in complex network theory, within which edge weight and node weight are calibrated with time and passenger flow.Subsequently, two network reliability evaluation metrics are proposed: time-weighted relative temporal efficiency and flow-weighted relative size of the largest connected subgraph.A gravity model is introduced to calculate compensatory functions generated from other nodes resulted from a node failure. Simultaneously, dynamic compensatory strength is computed to quantify complementary interactions between transportation networks.Finally, taking the Hu-Bao-E-Wu urban agglomeration as a case to perform simulation.The results reveal that the networks with complementary effects can maintain higher performance levels under attacks; under node failure due to be attacked, the conventional rail network can obtain 56.76% of compensatory relative temporal efficiency from other networks, whereas the high-speed rail network achieve 35.17% of compensatory relative size of the largest connected subgraph.
