城市轨道交通系统负荷评价标准研究

我国城市轨道交通快速发展,对已投入运营的线路定期进行安全评价尤为重要。确定了系统负荷重要评价项指标(线路负荷和站台负荷)的计算参数取值。通过乘客上车后选座行为及状态的分析,以车辆内部的服务水平标准(即立席密度评价标准)为参考依据,分析得出线路负荷的评价标准。分析了站台乘客集结过程及分布规律,以站台乘客排队服务水平标准和地铁站台设计标准为依据,研究得出站台负荷的评价标准。最后,以上海轨道交通10号线某日早高峰小时客流为样本,计算出其系统负荷值,并进行了评价。

Evaluation Standards of System Load for Urban Rail Transit

In recent years,urban rail transit in China has experienced a rapid development,it is essential to undertake safety evaluation of the operating lines regularly.The calculation parameter value of important system load evaluation indexes:line load and platform load are determined.By analyzing the seat selection behavior of passengers on board and the standing density index,the line load is obtained.By analyzing the aggregation process and distribution law of passengers on the platform,and based on the queuing service level and metro platform design standards,the platform load is calculated.Finally,taking a regular early peak passenger flow of Shanghai metro Line 10 as an example,the system load of rail transit is calculated and evaluated.
