| With the increasing demand of urban residents for travel demand and transfer efficiency among different transportation modes,and the demand of urban traffic planning,the number of comprehensive passenger transport hub of large railways is also increasing.Large scale railway comprehensive passenger terminal is an important place for railway station to connect all transportation modes.The layout of traffic facilities directly affects the transfer efficiency of pedestrians.This paper starts from the layout of traffic facilities in the hub,the pedestrian flow and pedestrian traffic characteristics,factors on the impact of the smooth operation of hub passenger flow increased,by using the method of Maxmin to calculate the proportion of the smooth operation of the impact of the largest hub of traffic facilities,the traffic facilities layout optimization,and comparative analysis of hub fluency before and after the optimization by using the method of traffic simulation.First of all,the comprehensive passenger transport hub in the large railway transport station facilities,the size of the number of pedestrian flow conflict and pedestrian traffic characteristics were analyzed and the construction influence factor index system,the index system is to establish various transport station facilities smooth effect on railway comprehensive passenger transport hub function,Maxmin method based on the proportion.By calculation and analysis in the case of increased traffic of the railway hub in the fluency of the greatest impact transport station facilities.Then,the calculation model of the impact of the largest transportation hub fluency station facilities optimization,through the transport station facilities of the quantity and the size of the adjustment of the negative impact of increased traffic hub to reduce to a minimum,and to assess the cost of adjustment.Finally,taking Chengdu East passenger station as an example,we investigate the characteristics of passenger flow and pedestrian data on the spot,introduce the method of pedestrian microscopic simulation,and use AnyLogic simulation software to simulate.In the case of increasing passenger flow,we conduct an intuitive comparative analysis of pedestrians’ streamline conflicts before and after adjustment and optimization of traffic stations and facilities that are selected by Maxmin model for the most comprehensive traffic hub of railway. |
