Operation Organization Of Urban Rail Transit During The Passenger Flow Of Planned Special Event

With the accelerating process of urbanization,a growing number of large-scale activities were held in the city.Due to the large activity has some characteristics such as strong agglomeration,short,uneven spatial and temporal distribution.The crisis induced passenger flow events have occurred,which has brought serious challenges to the normal operation of city rail.This paper focus on the large-scale activities which provides with short-term service,analyzes the dissipating process of passengers in subway network.Then analysis organize methods and applicable conditions of large-scale activities under the action of passenger flow of urban rail transit.We use urban rail transit network passenger flow evolution simulation model to simulate dynamic propagation process of passenger flow which caused by large-scale activities.This paper targets at the research of passenger flow network transportation and cooperative control,conduces related research as follows.Firstly,look deeper into the laws of arrival distribution of passenger flow during the large-scale activities,and analyze the statistical laws of ODs.This paper finds the law of Gaussian distribution of volume and periods of arrival passengers whom gather from special event.The key parameters of Gaussian distribution,which includes,mean and stand and deviation,correspond to the location of event venue,event types,age distribution and size of passengers etc.Secondly,this paper analyzes the transmission capacity and modifies the carrying capacity under special event flow,gives the station residence time and average necessary cushion time of working diagram calculating methods,analyzes the impact of flow which caused by special event.Thirdly,in this paper,we analysis the demographic statistical characteristic of urban rail transit network from perspective of complex network,then use urban rail transit network passenger flow evolution simulation dynamic propagation process in urban transit network.We find that passenger flow has impacted on the urban rail transit network through simulating,the rail transit network propagation character is related to the quantity of sides and nodes,and is closely related to the network topology.Lastly,we analyzes xi 'an urban rail transit network,focus on Ti Yuchang station in line 2 of Xi'an urban rail transit network.Research the characteristics and the rule to arrive passengers which caused by special events.Simulation the front and back effects on the rail traffic network which caused by special events.The Results show that after optimized,the influence of passenger flow all stations which caused by special events reduce,passenger flow can be quickly evacuated.
