摘要
公交换乘枢纽是公共交通的关键环节。通过对公交换乘枢纽的系统分析,分别从硬件设施、运营管理及信息化程度选取了具有代表性的指标,建立了能有效反映城市公交换乘枢纽的评价指标体系;建立了基于灰色关联度加权法的城市公交换乘枢纽运行效率评价模型;最后,以成都3个大型公交换乘枢纽为例,计算了枢纽的各项指标的评价值并进行综合排序,实例证实了该模型的可操作性和推广性。
To improve the capacity of signal intersection pedestrian crossing and the pedestrians’ safety, considering the influence of the pedestrian crossing width on pedestrian service level,this paper proposes that the typical signalized intersection pedestrian entrance and passengers flux be described as a queuing system at rush hours. The exponential distribution law of pedestrian arrival is obtained by field survey data fitting, and services follow a normal distribution law, and because the pedestrian at signalized intersections walk the line regularity with vacation properties, the queuing system is represented as the GI/G/1 queuing system with batch service. The optimized model with important constraints is built based on the busy and fallow period, providing a scientif-ic calculation basis for the crosswalk width.
