In the whole bus transit network, bus stop configurations significantly influence the system's operational efficiency. But it remains to be a challenge to set the proper number of lines for bus stops. In this paper, we firstly define the line-based bus stop capacity as the maximum number of bus lines that can be accommodated by a bus stop. Secondly, based on queuing theory, a mathematical model is established to describe the quantitative relationship between the line-based bus stop capacity and associated factors including bus stop capacity and departure interval of bus lines. Then, an iterative method is proposed to calculate the line-based bus stop capacity. Sensitivity analysis concerning major influencing parameters is conducted at last. The results show that the Acceptable Inbound Failure Rate and the boarding and alighting time are the most sensitive to line-based bus stop capacity.
