The bus delay under the influence of upstream stop at intersection was analyzed. The modeling scenario was divided into three categories according to whether the system set the bus lane and the bus station position was father than the farthest queue point of the intersection by analyzing the location of the stop upstream at the intersection, the signal timing, the stop time, the input flow and other factors. The bus delay model under the influence of the stop was established based on the traffic wave theory. All models were analyzed and calculated by the numerical simulation. Results show that the expected bus delay is only related to the cycle and the green signal ratio in the BL scenario. In the NBL1 scenario, the expected bus delay increases with the increase of traffic flow, cycle and red light duration, and has nothing to do with the bus stop time. In the NBL2 scenario, the expected bus delay first decreases and then increases as the distance of the station increases. The expected bus delay under NBL1 is the largest with the increase of traffic flow under the same conditions.
