高铁枢纽环线公交化列车新增运行线优化方法
Optimization method for adding extra train paths of mass transit operation in high-speed railway hub loops
摘要
Abstract
To fully utilize the interconnectivity advantages of the inner loop and connecting lines in high-speed railway hubs,aimed at serving both transfer passengers and urban travelers,this study ex-plores an optimization method for adding extra train paths in mass transit operations with a high-speed railway hub loop.First,the organizational model for Electric Multiple Unit(EMU)trains on the hub loop is analyzed in terms of train scheduling,EMU sourcing,and routing schemes.Second,with the objective of increasing high-speed train operation frequency on the loop line,a comprehensive optimi-zation model is developed for scheduling mass transit-type train paths,factoring in station routes,track utilization,and EMU routing schemes.Finally,a high-speed railway hub is selected as a case study.The research results demonstrate that,without altering original train assignments and using the same number of EMUs as the initial plan,the service frequency between hub loop stations can in-crease by 120%,and the minimum average departure interval between stations can be reduced to 14 minutes.The established model allows flexible application of various hub loop train scheduling plans,maximizing transportation capacity and advancing mass transit operations.These findings provide an or-ganizational strategy for implementing mass transit-type operations of EMUs in high-speed railway hubs.关键词
