Optimization of Train Operation Scheme for Urban Rail Transit Considering Dynamic Passenger Demand and Full-Length & Short-Turn Routing Modes
摘要
Abstract
Through the analysis of the temporal and spatial distribution characteristics of passenger travel demand,the 4 parameters logistic function was used for piecewise fitting the cumulative passenger flow curve thus to derive the calculation formula of passenger demand for each station at any time interval.With the consideration of the dynamic characteristics of passenger demand and the features of train departure time interval under full-length and short-turn routing modes,a multi-objective mixed integer nonlinear optimization model for train operation scheme was established,which aimed to reduce the average waiting time of passengers,increase the average full load rate of trains and decrease the total number of kilometers traveled by trains.An improved NSGA-II was used to solve this model,and the special coding approach was designed according to model characteristics.The actual operation data of Line 2 Xi'an Metro was taken as an example to optimize the train operation scheme of rail transit.Results indicate that the optimization scheme of train operation based on the non-fixed interval of departure time with dynamic passenger demand and the timely adoption of full-length & short-turn routing modes can effectively meet the interests and needs both for passengers and operators.关键词
