Research On Subway Emergency Passenger Emergency Evacuation

The primary concern of safety science is the life safety of personnel. In emergency situations such as emergency occurs, the safety evacuation as an important safeguard measures of personnel life safety is particularly important. Based on the preliminary observation of the Beijing subway stations, this paper selects the channel with the highest frequency of typical stations to carry out detailed observations, collects the data of the flow of passengers in channel and researches the population flow rate under different density, therefrom the crowd flow rate equation is derived of the Beijing subway. Through the questionnaire analysis of passenger evacuation behavior tendency, combine with on-the-spot observation, the individual behavior and group behavior of the passengers is studied and the results show that a large proportion of women and older middle-aged passengers will not be conducive to the rapid evacuation of passengers. According to the results of the above studies, the evacuation behavior of the Beijing subway passengers is simulated, the results show that the inertial behavior harm less than reentrant behavior during the evacuation of passengers. When the evacuation begin, at the same time, the station staff timely withdrawal of security facilities, although such behavior can reduce the evacuation time, but for the side platform station will cause an increase of bottleneck location. In the safety of different density case, side platform station is better than the island platform station. Through the simulation of the actual station, this study provides the basis for the design and construction of subway station in metro construction and operation department, as well as the establishment of emergency measures in the event of emergency.
