广州地铁6号线萝岗车辆段早高峰时段发车效率分析及其提升对策

Analysis of Vehicle Dispatching Efficiency During Peak Hours of Guangzhou Metro Line 6 Luogang Depot and Improvement Measures

基于广州地铁6号线萝岗车辆段的实际情况,分析了列车出段路径,并仔细测算了列车出段运行时间。测算发现,早高峰时段的列车出场运行平均时间为483 s,大于时刻表的计划运行间隔,进而导致萝岗车辆段列车出场延误。提出通过调整列车出场路径来减少列车出场时间。深入分析了限制车辆段发车能力的瓶颈位置,并针对性提出优化规章、提高出库速度,提高司机驾驶水平,优化检修库库门确认流程,以及提升司机的弓靴转换操作效率等一系列对策。建议将分段出场及正线摆放过夜车作为储备应急方案,并阐述了方案风险和预防措施。

Based on the actual condition of Guangzhou Metro Line 6 Luogang Depot,the train departing route is analyzed,and the depot-exiting time is carefully measured.The measurement founds that the average train exit time at morning peak hours is 483 s,longer than the planned interval on timetable,which further causes delay of Luogang Depot train dispatching.It is proposed to decrease the train exit time by adjusting the route.The bottleneck position that limits depot train delivering capacity is analyzed in-depth.Specific measures including regulation optimization,garage-exiting speed increase,driver ability improvement,optimization of inspection garage door confirmation process and efficiency improvement of driver pantograph shoe conversion operation are proposed.It is suggested to dispatch by section and to park overnight train on mainline as back-up plan.The risk and preventive measures of the scheme are expounded.
