摘要
受到对高集散效率需求的影响,目前越来越多高速铁路枢纽采用直连快速路的单层级结构模式进行进出站交通组织。从高速铁路枢纽布局、交通集疏散设计目标及交通集疏散架构3个方面进行高速铁路枢纽交通集疏散设计分析。以珠西枢纽江门站为例,提出交通集散系统规划设计方案,构建单界面分层过滤的零干扰外围道路集散系统、公交优先的多层循环的管道化进出集散系统、多点分散的换乘便捷一体化的内部集散系统并进行仿真分析。模拟结果显示,优化后高架匝道机动车延误减少效果明显,设计方案可以为提高枢纽的集散效率提供思路。
Influenced by the demand for high distribution efficiency, more and more high-speed railway hubs are adopting the single-layer structure mode of direct link expressway to organize the traffic in and out of stations. This paper analyzes the design of high-speed railway hub’s traffic collection and distribution from three aspects: the layout of high-speed railway hub, the design goal of traffic collection and distribution, and its structure. Taking Jiangmen station of Zhuxi hub as a study case, the planning and design scheme of traffic distribution system is put forward. At the same time, the zero interference peripheral road system with single interface and stratified filtering, the multi-layer circulation pipeline-type in-out system with bus priority, and the internal system with multi-point decentralized transfer and convenient integration are constructed and analyzed by simulation. The simulation results show that after optimization, the vehicle delay on the elevated ramp is significantly reduced, and the design scheme can provide ideas for improving the hub distribution efficiency.
