地铁运营中断下应急接驳公交调度方案研究
Study on Emergency Bus Dispatching Scheme for Subway Service Interruption
摘要
Abstract
[Purpose]In order to optimize the emergency response and address the inefficiencies observed in tradi-tional dispatch models,this study tries to develop a scheduling method,which considers a range of emergency dis-patch modes.[Method]Considering the characteristics of emergency parking lot dispatching capacity,vehicle transportation capacity,and vehicle rescue time,a multi-objective combination scheduling optimization model is constructed with the goal of minimizing the evacuation cost of emergency public transportation vehicles and mini-mizing the average passenger delay.Based on the characteristics of the model,a fast non dominated sorting genetic algorithm(NSGA-Ⅱ)was proposed to solve the problem.In order to improve the diversity of the population and the performance of the algorithm,corresponding improvements were made to the algorithm.The Pareto distribu-tion optimization solution set was obtained,and the optimal compromise solution was selected from it using a mem-bership function.Finally,the Nanchang Rail Transit Line 1 was used as an example to separately evaluate the emer-gency bus combination dispatch plan and the single scheduling scheme are solved separately.[Result]Results show that the proposed combination dispatch plan reduced passenger delay time by 20.48％and transportation costs by 16.96％compared to traditional single dispatch plans.Additionally,the improved NSGA-Ⅱ algorithm fur-ther reduced passenger delay time and transportation costs by 6.72％and 3.59％,respectively.[Conclusion]Sensi-tivity analysis shows that,with clear demands of stranded passengers,fleet size negatively correlated with the aver-age delay time of stranded passengers and positively correlated with emergency bus transportation costs.关键词
