Bus-stops in urban areas of major cities have several vivid characteristics, which include large numbers of bus lines, poor punctuality, and strong fluctuation of dwell time. With the rapid development of urban public transit, the arriving buses at stops in unit time are growing. Thus, the queuing phenomenon is very common in multi-line bus-stops. There is no doubt that bus operations at stops affect the road link capacity. Especially when bus queuing exists in the upstream of the stop, the reality will be more complicated. In this paper, road link capacity is estimated for different stages of bus-stop operation. The temporal impact factor is calculated to reveal the occupation of bus-stop on road link capacity. Moreover, a classical queuing model is proposed to analyze the waiting time for buses to enter the stop and the overflow probability of a multi-line bus-stop. A case study is carried out to illustrate the effect of queuing at bus-stop on road link capacity. Results show that compared with other conditions, the overflow probability is small when the number of berths is three. And, if the number of lanes on road link is more than three, the influence of the bus-stop can be neglected.
