By simulating the field situation of Xi 'an Road Station in Dalian, this paper makes quantitative judgment through passenger flow, crowded coverage area of passenger flow, proportion of passenger flow retention and crowd flow, determines the warning threshold: Level 4 (green) means that the load rate is more than 80%, there is no stranded crowd in the station hall, the traffic is smooth, it needs to pay attention to the station information and status monitoring, and timely response; Level 3 (yellow)	cache/ajst-3873.pdf	txt/ajst-3873.txt
