铁路客运枢纽车道边落客长度指标研究

Research on Index of Drop-off Length at Lane Side in Railway Passenger Terminal

目前,我国较多铁路车站旅客落客平台均出现常态化拥堵问题,分析发现,造成落客平台拥堵的主要原因是车道边落客长度规模不合理。对车均落客长度这一影响规模计算的关键性指标进行实验研究。通过96组对照实验模拟落客行为,定义驶入长度、停车区长度、驶出长度、驶入角及驶出角5个特征指标并进行轨迹分析,明确了驶入速度、车辆尺寸及驾龄等因素对指标值的影响程度,并给出了指标的建议区间值9.5~12.5 m。在空间紧张的情况下,建议区间值可进一步缩小为8~10 m。

At present,the passenger drop-off platforms of many railway stations have normalized congestion problems,mainly due to the unreasonable scale of the length of the drop-off at the side of the lane.The key index of the average drop-off length of vehicles affecting the calculation of scale is studied experimentally.96 groups of control experiments are used to simulate the drop-off behavior to define five characteristic indicators of inbound length,parking area length,outbound length,inbound angle and outbound angle.The trajectory analysis is carried out to clarify the impact of inbound speed,vehicle dimension,driving years and other factors on the indicator value.The recommended interval value of the index is 9.5~12.5 m.In case of tight space,the recommended interval value can be further reduced to 8~10 m.
