Reseatch On The Capacity Matching Of Inbound Equipment In Urban Railway Transportation

With the large-scale construction of new urban rail transit lines,the number of stations increases rapidly.The road network has been constantly improved,attracting more and more passengers year by year,but at the same time,the imbalance between the supply and demand of some station equipment becomes more and more obvious.Capacity is related to the size and layout of station equipment.How to measure the capacity of station equipment,master the matching situation of equipment capacity,and objectively evaluate the capacity matching of the whole station.In view of these problems,the thesis will conduct in-depth research,the specific contents of which are as follows:(1)Systematically analyze passenger travel characteristics of rail transit and passenger flow organization characteristics of passenger station.From the analysis of passenger travel characteristics,the arrival of inbound passenger flow law.Based on the characteristics of the equipment and circulation of rail transit station,the key points of passenger flow organization in different periods are put forward.(2)In this paper,SPSS and Matlab are used to combine the queuing theory model and its related parameters and indicators.The queuing theory model of the in-station tandem equipment is established,and the psychological behavior of passengers is introduced.Systematic analysis of queuing passengers of different equipment in the station;Design survey plan and conduct field data survey.(3)Firstly,this paper studies the passing ability of automatic ticketing system,security check system and automatic ticketing system.It includes the overview of the equipment,the introduction of the use method,and the analysis of the influencing factors of passenger use time.The passage capability model of ticket vending machine based on passengers’ proficiency in purchasing tickets,the passage capability model of security check equipment based on luggage size and the passage capability model of automatic ticket checking system based on passengers’ ticket type were constructed.Then,in order to establish the passing capacity model of the station tandem equipment,field research was conducted to obtain the time required for different types of passengers to pass through the ticket vending machine and check in.SPSS software was used for variance analysis,correlation analysis and independence analysis of different attributes of passengers passing through various devices.According to the principle of objective planning in operational research,Matlab is used for programming.The objective function is the number of passengers queuing for the station equipment.The optimization objective is to minimize the function value of the objective function.The first kind of constraint condition is that the average number of adjacent devices can not exceed the maximum allowed by the station.The second kind of constraint condition is that the average queue number of adjacent devices should not exceed the maximum allowable between devices on the passengers’ inbound streamline.Through the priority factor of the objective function,the importance degree of different reference indexes is defined,and the weighting coefficient of different kinds of equipment is assigned to the same grade,which will be closer to the actual station situation.(4)Fuzzy evaluation is applied to the matching model of station series equipment.Through the use of the station equipment by the influence of different factors in the process of quantitative judgment;Through the weight setting,the matching evaluation set of station equipment is established.
