基于可变编组的地铁列车延误运行调整研究
Research on adjustment of delayed metro train operations based on variable formation
摘要
Abstract
To address the issue of train delays caused by uncontrollable factors during operation,this study investigates the impact of various adjustment strategies under a variable train formation operation mode on both passengers and subsequent train services.First,a train delay adjustment model is devel-oped based on the variable formation operation framework,incorporating constraints such as train for-mation,arrival and departure times,rolling stock circulation,headway intervals,and passenger flow calculations.Then,the model optimizes four key decision variables,train formation status,dwell time,section running time,and headway,to achieve two main objectives:minimizing the number of stranded passengers and minimizing the deviation between the actual and scheduled timetables.Fi-nally,using Shanghai Metro Line 16 as a case study,three distinct delay scenarios are simulated and solved using the CPLEX solver.The research results indicate that in different scenarios,for shorter de-lays,there is no need to implement coupling or decoupling strategies.However,for longer delays,these strategies are necessary to mitigate operational impacts.Within the same scenario,allowing cou-pling and decoupling operations significantly reduces both the impact on subsequent trains and the total number of stranded passengers compared to scenarios where such adjustments are not permitted.关键词
