基于系统聚类的沪宁城际高铁列车停站改进方案

摘要

Train stop scheme is an important part of passenger train operation. Based on definition of the intercity high speed railway concept and analysis of Shanghai-Nanjing intercity high speed railway operation condition as well as the existed main problems in the train stop scheme, a system cluster grading method of the stations was put forward according to the passenger flow and the stations of Shanghai-Nanjing intercity high speed railway were divided into 5 grades. By comparing the train stop schemes and according to the concept of public bus, an improvement scheme and some improvement suggestions on the peak periods of different average service interval stop within Shanghai-Nanjing intercity high speed railway stations were presented so as to provide a powerful technical support for train operation organization.%列车停站方案是旅客列车开行方案优化的重要环节。在定义城际高铁概念和分析沪宁城际高铁运营状况以及列车停站方案存在主要问题的基础上，提出根据客流量采用系统聚类法对车站进行分级的方法，并将沪宁城际高铁各站分为5个等级。对比现行列车停站方案，按照公交化的理念，提出了沪宁城际高铁基于高峰和平峰时段车站不同平均服务间隔的停站改进方案和改进建议，为城际高铁运营组织提供有力的技术支撑。
