摘　　要：BRT站距影响乘客到达BRT站点所花费的平均时间,这种影响对步行到站者的出行显得尤为明显。首先,对BRT走廊辐射区域进行了细致的解析,以到站时间受站距影响较大的步行到站者为研究对象,分析步行到站者的平均到站时间,得到了步行到站平均时间同站距的函数关系。在此基础上,以增加站点数量造成的平均步行到站时间减少同BRT车辆运行时间的增加两者之间的平衡为目标,建立了BRT走廊站距优化模型,给出了模型参数的标定方法。该模型对BRT影响区进行细化,更加符合实际情况,能为BRT实际设站提供一定的参考。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 .
