基于运力协调的城市轨道交通网络列车运行计划优化
Optimizing urban rail transit network operation plans based on transport capacity coordination
摘要
Abstract
In view of big passenger flow volume and high passenger risk at transfer stations during the peak period,this paper studied the coordination method for urban rail transit network transportation organization from the perspective of capability matching.The change rules of passenger flow were analyzed,and the calculation methods for train evacuation capacity,waiting passenger demand and the largest number of people gathered on the platform were determined.The concept of capacity coordination degree (CCD) was proposed used to describe the matching degree between the traffic demand and the transport capacity of each line.Based on this,taking the optimal comprehensive CCD of the transfer station as the goal,the first train departure time and train running interval as decision variables,and the guarantee of passenger safety at the station as the main constraint,a nonlinear integer programming model of train operation plans collaborative optimization was established,and the genetic algorithm was designed.A case study of a two-line intersecting network was carried out.The results show that,after the use of capacity coordination scheme,the total number of trains only increases by 1,the remaining passengers reduce by 68.44%,comprehensive CCD is closer to 1,and the largest number of people gathered in big passenger flow directions decrease by 11.77% and 19.68%,respectively.The transport supply can better meet the passenger demands in all directions,thus improving the interests of both passengers and operating companies.关键词
