北京市轨道交通站点周边区域共享自行车运行不均衡性研究
|
摘要
共享自行车是解决短距离出行和"最后一公里"交通问题的有效手段,但也引发了一些交通问题,尤其是在局部区域车辆淤积现象对其他交通出行方式产生了影响.本文将共享自行车骑行的租、还空间位置对应为出行的起讫点,基于出行OD分析了其整体时空运行特征和在轨道交通站点周边区域运行特性.本文还分析了共享自行车在轨道交通站点周边区域出现不均衡性的外部和运行特征因素,基于此提出了不平衡性量化值的计算模型.通过模型计算了典型轨道站点周边区域的不均衡性数值.该模型能够评估共享自行车在轨道交通区域运行的差异,以支持重点区域调度和监管.
Bicycle-sharing is an effective way to solve short-distance travel and"last mile of public transport",but it also brings problems, especially the affect to other transport patterns due to the accumulation in certain area.The locations of rent and return of one bicycle-sharing cycling are transferred into origin and destination in the paper, and the time-spatial characteristics of the whole city and rail transit station areas are analyzed based on OD data. External and characteristic factors which influence the disequilibrium of bicycle-sharing in rail transit station areas are analyzed. A model to estimate the value of disequilibrium is proposed. Disequilibrium values of some typical station areas are computed with it. The differences of bicycle-sharing in rail transit station areas can be evaluated with the model to support distribution and supervision with focus.
