广州地铁网络化运营运能提升综合研究与实践

从广州地铁线网运营现状出发,分析既有运输组织存在的停站时间长、区间运行速度偏低、旅行速度低、折返能力不足等制约运输能力提升的瓶颈与问题。针对现状运营存在的问题,在压缩停站时间方面提出设备响应速度优化、压缩司机安全确认时间、站台客流组织优化等措施;在压缩区间运行时间方面提出提高区间运行速度、降低曲线限速、减少运行图冗余等措施;在提高折返能力方面提出压缩折返车站停站时间、提高道岔侧向通过速度及合理选用折返线配线形式等措施。从理论上分析验证综合运能提升措施的实施效果,经分析得出:客流压力较大的3、5号线车站追踪能力、区间追踪能力及折返能力,采用相应措施优化后可满足正线最小行车密度2 min的要求。

Capacity Expanding of Guangzhou Metro under Networking Conditions

Constraints on the expansion of transport capacity,including long dwell time,low interval running speed,low travelling speed,low turn-back capacity and so on,as well as the countermeasures are analyzed by using networking operation of Guangzhou Metro as an example.To compress dwell time,the methods for improving the response speed of the device,compressing the driver's safety confirmation time,and optimizing organization of platform passenger flows are proposed;to compress the interval running time,the methods for increasing interval nnning speed,reducing speed limit at curves,reducing running chart redundancy are offered;to increase the turn-back capacity,the methods for reducing dwell time for turn-back station,increasing turnout speed and reasonable selection of turn-back wiring form are put forward.By taking these measures,station tracking,interval tracking,and turn-back capacity of Line 3 and Line 5 with larger passenger volumes can meet the minimum departure interval of 2 minutes.
