公交站点对路段通行能力的影响研究

Study of the Effect of Bus Stop on Roadway Link Capacity

研究直线式和港湾式公交站点对路段通行能力的影响,分析了公交站点影响区域内的车辆运行特性,使用排队论和间隙理论分别推导了直线式和港湾式站点路段的通行能力计算模型,并通过仿真验证了模型的有效性,平均相对误差分别为2.73%和3.10%,说明本文模型能够较准确地测算出公交站点影响路段的通行能力.使用上述模型得到了公交站点对路段通行能力的影响系数,并重点分析了公交停靠时间对该系数的影响.

The influence of on-line bus stop and bus bay on the capacity of roadway links is studied. The vehicle operating characteristics are analyzed by means of bus influence area for each type of bus stop. Based on this calculation model, the capacity of roadway links is developed using queuing theory and gap acceptance theory. And the validity of the model is verified by VISSIM simulation, the average relative errors are 2.73o//oo and 3.10~/＇00 respectively. It shows that this model can accurately calculate the capacity of links affected by bus stops. Finally, the adjustment factors of bus stop are achieved by the model, and some factors, especially dwell time, are analyzed.
