深圳至大亚湾城际铁路运输组织方案研究

Research on Transportation Organization Scheme of Shenzhen-Dayawan Intercity Railway

城际铁路的运输组织方案直接影响运输效率、运输能力以及服务便捷性,会对客流产生导向作用。以深圳至大亚湾城际铁路为例,依据预测的跨线客流量,在满足服务频率的前提下对跨线列车开行方案进行分析,结合客流特征,在满足短途通勤客流需求的前提下,兼顾长途客流的时效性需求,创造性地提出本线需开行大站停和站站停两种列车;进而根据列车编组和定员设计列车运行交路和全日开行计划,在对本线及跨线区段高峰小时和全日能力适应性及利用率进行详细分析计算的基础上,提出研究年度如运量进一步增长,可采用减少大站停列车对数、增开站站停列车对数和压缩追踪间隔等措施进一步提高运输能力。研究结论有力地支撑了深圳至大亚湾城际铁路的建设,并为粤港澳大湾区其他城际铁路的运输组织方案提供参考。

The transport organization scheme of intercity railway has direct impact on transport efficiency,transport capacity and service efficiency,and provides a guiding effect on passenger flow.This paper takes the intercity railway from Shenzhen to Dayawan as an example,analyzes the cross-line train operation plan on the premise of meeting the service frequency based on the predicted cross-line passenger flow.Combing with the prediction of across-line traffic on the premise of meeting the demand of short-distance commuter traffic and balancing timeliness requirements of long-distance passenger flow,the paper creatively proposes two kinds of trains:train stopping at large stations and train stopping at each station.Then,according to the train formation and train capacity,train operation interchange and full-day operation plans are fulfilled.On the basis of the detailed analysis and calculation of the capacity adaptability and capacity utilization of this line and the cross-line section in peak hours and full-day,it is suggested that if the traffic volume increases further in the research year,the transportation capacity be further improved by reducing the number of trains stopping at large stations,increasing the number of trains stopping at each and compressing tracking interval.The research results strongly support the construction of the Shenzhen-Dayawan intercity railway and provide references for the traffic organization plan of other intercity railways in the Guangdong-Hong Kong-Macao Greater Bay Area.
