Abstract: Bus Rapid Transit (BRT) in China is still at its initial stage,though it has been introduced by some cities.In order to ensure the rapid transit of bus,research on the platform scale of BRT has become increasingly important.Based on the factors influencing the platform scale of BRT,combining with the relevant knowledge of queuing theory,the further research is carried out,which discusses the impact of platform scale from passengers transfer volume and vehicle lots.The calculating model of platform scale based on the passengers transfer volume and vehicle lots is proposed.The model can calculate the minimum size of the platform and the minimum length,adjust the conflicts when the indicators conflict,by using the minimum width as checking indicators and in accordance with adjusting principles.Finally,a reasonable platform scale is set up.

Key words: traffic engineering, scale of platform, Queuing Theory, BRT (Bus Rapid Transit), vehicle lots

摘要： 快速公交系统(BRT)的研究在我国尚处起步阶段,目前已有一些城市引进了BRT,为了保证公交的快速通行,对BRT站台规模的研究日益重要。首先找出快速公交站台规模的影响因素,由此结合排队论的相关知识,从站台乘客换乘量和泊位对站台规模的影响进行了深入探讨,提出了基于乘客换乘量和基于泊位的站台规模计算模型。该模型可以计算出站台的最小面积和最小长度;再以最小宽度为验算指标,当指标冲突时,结合调整原则,最终得到合理设置的站台规模。
