在分析城轨客流特性的基础上，提出线网实 时客流的监测算法;利用地理信息系统(GIS)技术，动 态展示城市轨道交通线网实时客流分布态势;设定预 警研判机理，对超过限定预警值的车站、区间的客流进 行监测预警;借助GIS动态定位特性，辅助实现公交接 驳的紧急疏散，以满足线网运营的可视化、高效的现代 化管理。

On the basis of analyzing the characteristics of urban rail passenger flow，the paper proposed a line network real- time passenger flow monitoring algorithm which dynamically displays the real-time passenger flow distribution trend of urban rail transit network by using GIS ( Geographic Information System) technology． A warning-oriented mecha nism was also established for monitoring an early warning passenger flow on a station or line interval that exceeded the limit warning value，which can help to realize emergency evacuation by bus connections with GIS dynamic positioning features． This meets the requirements of the line network operators' visual and high－ efficiency modern management．
