Optimization Strategies for Transportation Network Resources in the Context of Intercity Commuting:A Case Study of Beijing-Tianjin Intercity Railway
摘要
Abstract
With the continuous growth of intercity commuting demand,major transportation hubs are facing increasing passenger flow pressure.There is an urgent need for guidance with the integration of four railway networks(mainline railway,intercity railway,urban railway,and subway),implementation of multi-level optimization and upgrading of existing road network resources,and acceleration of the construction of an integrated and efficient travel service system.This paper took Yizhuang Station on the Beijing-Tianjin Intercity Railway,as a case study.By analyzing existing train operation data and passenger flow characteristics,typical issues such as insufficient train stop coverage and underutilized interlinked capacity were identified.A dynamic coupling optimization model for train stops and formation based on multi-time period collaboration was constructed to address issues such as the uneven distribution of passenger flow and the low proportion of train stops in the context of intercity commuting.Through the design of a heuristic algorithm,the train working diagram for the direction from Tianjin to Beijing was optimized.The results show that the Beijing-Tianjin Intercity Railway needs to adopt larger train formations during the morning peak to release line capacity and create conditions for adding stops at Yizhuang Station.Meanwhile,by quantifying the number of train departures,the passenger flow distribution at major railway hubs in Beijing can be balanced.Finally,policy suggestions are put forward,including accelerating the integration of four transportation networks and integrated travel services,improving fare policies,and implementing government and social capital cooperation models to develop tourism resources.These measures aim to enhance the attractiveness of Yizhuang Station to passenger flow,stimulate economic development in the surrounding areas,and achieve overall network quality improvement and efficiency enhancement.关键词
