Harbor-style bus stops have large capacity, little influence on the main road, which is also safe and convenient for passengers to get aboard or getting off. However, the capacity of main road was reduced when buses arriving or departing the bus stops. Based on the analysis of procedure of bus arriving and departing the harbor station, with the combination of queuing theory with gap theory, we analyzed the influence of harbor style bus stop on main road capacity, which is studied by normal and spillover scenarios. For the normal scenario, with the procedure analysis of arriving and departing bus stop, influence model on main road was established, for the spillover scenario, we established the corresponding model, with the considering of the influence of lane change behavior of other vehicles on the outmost lane. The simulation analysis shows that the error of the model in two scenarios are 2.8% and 2.9% respectively, which is satisfied to reflect the influence of harbor style bus stop on main road capacity. From the case study, we can conclude that in the normal scenario, with the increasing of bus arrival and volume in outmost lane, the reduction coefficient of main road increased slowly, in the spillover scenario, when the bus arrival rate is more than 40veh/h , and volume in outmost lane more than 900veh/h, the reduction coefficient of main road shows accelerating trend.
