公交停靠站公交车损失时间研究

Time Loss of Transit Vehicles at Bus Stops

公交停靠时间影响着公交行程时间、公交准点率以及公交通行能力。文中从理论上阐述了公交停靠站公交车辆停靠时间及其组成部分。为定量分析停靠时间中的损失时间,调查了南京市几个典型的公交停靠站,并综合分析了损失时间的大小、离散程度以及影响因素。研究结果表明,公交泊位数大于2时和公交泊位数小于等于2时的公交车损失时间有很大不同,在泊位数小于等于2的公交停靠站,损失时间较小,且基本保持恒定;在泊位数大于2的公交停靠站,损失时间增大,且受泊位数以及停靠站内已停公交车的影响。

Bus dwelling time at bus stops affects travel time, on-time ratio, and route capacity. This paper theoretically analyzes bus dwelling time and its components. In order to analyze the bus dwell time quantitatively, this study carries out surveys at several bus stops in Nanjing. Moreover, the magnitude, dispersion and influencing factors of time loss of transit vehicles are analyzed. Study results show that time loss at bus stops with one or two berths is extraordinarily different from those with three or four berths. The time loss remains small and constant when the bus stops have no more than two berths. On the other hand, when the bus stops have three or four berths, the time loss increases significantly and it is affected by the number of berths within the bus stops and the number of buses dwelling in the stop.
