Passenger Control Scheme For Urban Rail Transit Transfer Station

With the development of urban rail transit network, the existing station cannot meet the travel needs of passengers, especially in the morning and evening peak period of the transfer station. In response to the increasing passenger flow in transfer station and reduce the security risks caused by the excessive passenger flow, the control measure for large passenger flow is needed.First, the type of urban transit rail station is classified. Then we study the node transfer station as of this article, analysis the peak of passenger flow control rules; further identified the passenger flow control trigger indicators in order to determine passenger traffic control start time and the end time of passenger control program search conditions, and designed the method of calculation of the index.Secondly, the network abstraction of the transfer station is depicted, based on the analysis of influencing factors on the peak of the passengers path, combined with the station management requirements for large passenger safety organizations, the passenge r flow control model in peak period is made, using the branch and bound search algorithm on the search of passenger flow control path in peak period.Based on the search path of the passenger control, with the trigger index value larger than passenger Control of the facilities as a starting point, according to the parameters of path points, properties to determine the passenger control nodes, and use the maximum transmission capacity of the station to determine the capacity of the control node in order to determine the Specific measures in control nodes to form a complete passenger control program.Finally, select the Guangzhou Kecun subway station as a case study of objects, built the abstract pedestrian network of Kecun station. With the calculating methods of passenger flow control trigger index, we get the site, channel, staircase passenger flow control threshold of Kecun station. Determine whether the facilities of the morning rush hour is more than the passenger flow control trigger index value based on the actual data from investigation, then form the passenger flow control scheme according to the results of Kecun station in morning peak period according to the verdict.By comparison with the actual Kecun verify the rationality of this article passenger flow control method and Provides a theoretical basis for the need to develop passenger flow control scheme of the station.
