MAS-based Research On Synergy Evaluation Of Passenger And Train On Urban Rail Transit

With the continuous development and improvement of urban rail transit system,more and more passengers choose to travel through urban rail transit,and the passenger flow in the network is also increasing.Urban rail transit is a huge and complex system.While passengers' requirements for operation of the system become more and more stringent,the increasing demand also brings tremendous pressure to the system.Rail transit operators in various cities adapt to the increasing passenger demand by adjusting train operation plans,but there is still no exact and objective evaluation criterion to evaluate the synergy between the adjusted train operation plans and passenger demand,which leads to the poor coordination between the adjusted train operation plan and passenger demand and results in the waste of transport capacity or the phenomenon that it is difficult to meet passenger demand.Therefore,it is very urgent and necessary to establish an appropriate evaluation index system to evaluate the synergistic relationship between train operation plan and passenger flow demand,as well as the more important modeling and calculation methods to obtain these evaluation indexes.On the basis of the above research background,this paper firstly analyzed the current research situation domestically and abroad from the aspects of evaluation of timetable and the adjustment of train operation plan,and proposed Multi-Agent-system algorithm to realize the simulation of micro-passengers.Secondly,based on the characteristics and arithmetic ideas of Multi-Agent-System technology,the passenger-train interaction model of urban rail transit is established by analyzing the attributes and behavior characteristics of passengers and trains in the rail transit system.The interaction between passengers and trains on the basis of the road is realized through the model,and the model is realized by using MATLAB programming technology.Then,based on the model,the factors affecting the satisfaction of passengers and operators of urban rail transit are analyzed,and a passenger-train synergy evaluation system for urban rail transit,which includes comfort satisfaction degree,loss satisfaction degree,delay satisfaction degree,stranded satisfaction degree,congestion satisfaction degree for passengers and coefficient of revenue and coefficient of energy consumption for operators,is established with the consideration of both passenger satisfaction and operator satisfaction.At the same time,on the basis of MAS model,the chromatic aberration diagram is used to visualize the calculation results.Finally,taking Beijing Metro Line 1 as an example,this paper discusses the synergy between train operation plans with different departure intervals and different passenger flow demands,compares the synergy between train operation plans and passenger flow demands under normal and emergency conditions of network,verifies the feasibility and validity of the model and index system and make a theoretical basic for the evaluation of the train operation plan of urban rail transit.
