Abstract: The spacing between bus rapid transit (BRT ) stops influences the average travel time that the passengers spent for getting to BRT Stops .This effect is greater for the passengers who walk to the BRT Stops .First ,this paper analyzed the area affected by the BRT corridor ,and studied the average walking-to-stop time affected significantly by the stop spacing .The functional relationship between the average walking-to-stop time and the stop spacing based on the studies was obtained .Based on the functional relationship ,the balance between the walking-to-stop time reduction and bus travel time increase caused by the increase of the number of BRT stops was taken as an objective function ,and a BRT stop spacing optimization model was developed .Meanwhile ,the paper proposed a parameter calibration method .The model reflects more realistic condition ,which can provide a certain reference for the establishment of BRT stops .
