考虑客流拥堵的城轨网络脆弱性评估
Vulnerability analysis of urban rail transit network based on passenger crowding
摘要
Abstract
Regard passenger crowding caused by interruptions of urban rail transit network,this paper developed a quantitative framework for assessing vulnerability of urban rail transit network.The framework utilized dynamic transit assignment to de-scribe the time-dependent distribution of passengers in the system and used generalized travel cost growth as the indicator of vulnerability of urban rail transit network.Stations and time period of access restriction control could be determined by the wait-ing passenger amount in stations.It performed simulation experiments to examine the effectiveness of this approach using data from Beijing Metro.The simulation test results show that this proposed quantitative framework is able to describe the time-de-pendent passengers crowding situation after interruptions and can serve as data and decision support for emergency passenger organization plan.关键词
