摘要:

城市群综合客运网络级联失效抗毁性研究,有助于提高城际出行的安全性及运输效率。为了更加贴近实际情况,基于多层复杂网络理论与实际客流构建城市群综合客运网络模型,以单位时间为步长建立考虑时间特性的客运网络级联失效抗毁性模型,提出时空两维度的评价指标进而分析每个时段的网络情况。以呼包鄂榆城市群为实例,研究结果表明:过载能力调节参数值为1.2时网络抗毁性较强,并且随着过载能力调节参数的加大,对网络抗毁性的改善并不明显;负载调节参数值大于1.2时,网络抗毁性明显变差。

Abstract:

The cascading failure invulnerability study of comprehensive passenger transport network in urban agglomeration is helpful to improve the safety and transportation efficiency of intercity travel. In order to be consistent with the actual situation, a comprehensive passenger transport network model for urban agglomerations is constructed based on multi-layer complex network theory and actual passenger flow. The passenger transport network cascading failure invulnerability model considering time characteristics is established with unit time step. The spatial and temporal evaluation indexes are put forward to analyze the network situation in each period. Taking Hu-Bao-E-Yu urban agglomeration as an example, the results show that the network invulnerability is stronger when the overload capacity adjustment parameter value is 1.2, and the improvement of the network invulnerability is not obvious with the increase of the overload capacity adjustment parameter. The network invulnerability becomes significantly worse when the load adjustment parameter value is greater than 1.2.

Key words: integrated transportation, time characteristics, cascading failure, comprehensive passenger traffic network, invulnerability, urban agglomeration
