Stations on Bus Rapid Transit (BRT) lines ordinarily control lineudcapacity because they act as bottlenecks. At stations with passing lanes, congestionudmay occur when buses maneuvering into and out of the platform stopping laneudinterfere with bus flow, or when a queue of buses forms upstream of the stationudblocking inflow. We contend that, as bus inflow to the station area approachesudcapacity, queuing will become excessive in a manner similar to operation of a minorudmovement on an unsignalized intersection. This analogy was used to treat BRTudstation operation and to analyze the relationship between station queuing andudcapacity. We conducted microscopic simulation to study and analyze operatingudcharacteristics of the station under near steady state conditions through outputudvariables of capacity, degree of saturation and queuing. In the first of two stages, audmathematical model was developed for all stopping buses potential capacity withudbus to bus interference and the model was validated. Secondly, a mathematicaludmodel was developed to estimate the relationship between average queue anduddegree of saturation and calibrated for a specified range of controlled scenarios ofudmean and coefficient of variation of dwell time.
