公交站台进出乘客对邻接非机动车道通行能力的影响

Impact of Inbound and Outbound Passengers form Bus Stop on Neighboring Bicycle Lane Capacity

为给公交站台处邻接非机动车道的安全设施设计提供理论依据,采用交通冲突解析技术,研究了公交站台进出乘客对相邻非机动车通行的影响。通过分析进出站乘客与非机动车的冲突过程与发生条件,基于人非冲突概率模型,构建了进出站乘客影响下的基本通行能力模型。在此基础上,考虑影响通行能力的因素具体涵盖车道有效宽度、电动车比例、时间障碍率和信号折减,计算出相应的基本通行能力修正系数,最后得到进出站乘客影响下的实际通行能力模型。实例应用结果表明:进出站台的乘客与非机动车辆之间的冲突对非机动车道通行产生了较大的影响,其通行能力大约降低了17.53%;通过模型运算获得的结果与实际通行能力大约存在4.8%的偏差值。

In order to provide a theoretical basis for safety facilities design of bicycle lane neighboring bus stop,the traffic conflict technique was used to analyze the effect of inbound and outbound passengers form bus stop on the bicycle flow on neighboring bicycle lane. By analyzing the conflict process and conditions of passengers entering and leaving the station and non-motor vehicles,a basictraffic capacity model under the influence of passengers entering and leaving the station was constructed based on the conflict probability model of passengers and bicycles. On this basis,adjustment factors of the basic capacity were calculated by considering the influential factors of the capacity including the effective width,the traffic composition,the time influence rate and signal reduction. Then an actual bicycle capacity model under influence of inbound and outbound passengers was established. Application results show that the bicycle lane was decreased by approximately 17.53% under the influence of inbound and outbound passengers. The absolute error between the observed capacity and the estimated capacity is only 4. 8%.
