摘要: This chapter describes the methods now employed for vulnerability analysis of public-transport networks. The main focus this work is on railway networks, particularly urban metro systems. Typological are widely applied, using standard metrics node degree, characteristic path length, centrality, and network efficiency, but most advanced studies have gone further, in defining new versions these that include variables such as passenger flows, origin–destination travel patterns, generalized times. Perhaps serviceability method based link centrality developed by Cats Jenelius their colleagues. applicable to multimodal transit systems dynamic, able handle time-of-day day-of-week variations, stochastic nature line operations, demand. Changes welfare an impact service disruption provide a criterion assessment importance, exposure, criticality method. There no reported application accessibility-based analysis, development accessibility indices, expressly systems, can be seen precursor near future.
