Research On Emergency Organization Of Sudden Passenger Flow In Urban Rail Transit

Nowadays the ground traffic congestion has became one of the most important questions which need to be solved for many cities,because of the highly transport capacity?the relative independence?the high speed?the safety and the comfortable characteristics,the urban rail transit has became the aortic in city.Developing with the economic,the activity in city also growing,it is easy to initiation sudden accident and the urban rail transit system bear huge pressure.Otherwise the operation of urban rail road is tend to networks,the dissipate of large passenger flow will be more complex.This article analysis the spread characteristic of large passenger flow and the emergency organization in urban rail transit.This article analysis the process of large passenger flow and put forward the method to distinguish different flows,through the structure research of network and topology,the complex network theory is proved to be useful in transit network analysis,through the station of urban rail transit analysis the spread and dissipate process in different stations and compute the changes of transportation ability and the delays of the trains.Research the emergency organization of large passenger flow,this article through the rail organization and the passengers control in station to control the spread of passengers flow in networks.Establish the passengers spread model SIRS and take Chongqing rail transit as an example to research the spread process,analysis the effectiveness of emergency organization with the changes of crowd stations.
