客运枢纽送站坪出租车车道的交通特性及通行能力研究

Study on Traffic Characteristics and Capacity of Taxi Lane at Delivery Apron of Passenger Transport Hub

为了提高客运枢纽的运行效率,缓解送站坪交通拥堵情况,对大型综合客运枢纽送站坪出租车车道进行研究。构建了出租车落客区域通行能力的计算模型,并对该模型进行了理论分析,分析结果表明:1)随着落客区域长度的增加,出租车落客区域的通行能力有所提升,但流量增量逐渐降低;2)降低低速区域车辆速度造成的影响要高于降低高速区域车辆速度造成的影响;3)中游低速区域不宜设置落客区域的人行横道。通过仿真模型对理论分析结果进行了验证,验证结果表明:当落客区域长度增加300%时,流出流量仅增加了11.2%,人行横道位于100 m位置时的流量增量明显减少,甚至出现流量减少现象,该验证实验结果与理论分析结果一致。

In order to improve the operation efficiency of the passenger transport hub and alleviate the traffic congestion on the delivery apron,the taxi lane on the delivery apron of the large-scale comprehensive passenger transport hub is studied.The calculation model of traffic capacity of taxi drop off area is constructed,and the model is analyzed theoretically.The analysis results show that:1)With the increase of the length of the drop off area,the traffic capacity of the taxi drop off area has been improved,but the flow increment gradually decreases.2)The impact of reducing vehicle speed in low-speed area is higher than that in high-speed area.3)Pedestrian crossings in the drop off area shall not be set in the low-speed area of the midstream.The theoretical analysis results are verified by the simulation model.The verification results show that when the length of the drop off area increases by 300%,the outflow flow increases by only 11.2%.When the pedestrian crossings are located at 100 m,the flow increment decreases significantly,and even the flow decreases.The verification experimental results are consistent with the theoretical analysis results.
