摘　　要：交通拥堵和环境污染是城市交通稳定发展的制约因素。为研究城市公交专用道的设置对机动车尾气排放和交通流的影响,采用交通仿真系统VISSIM以及尾气排放模型MOVES搭建了公交专用道设置对机动车尾气排放影响的量化分析模型,以西安市南门到电视塔路段为研究对象,选用了三种不同的公交专用道设置方案:不设置专用道、路中式专用道、路侧式专用道,仿真分析设置不同公交专用道对机动车尾气排放的影响。结果表明:设置公交专用道后整个路网所有机动车的尾气排放总量都得到了明显的改善,路中式公交专用道的尾气排放量最少,路侧式次之,不设置公交专用道的尾气排放最大;针对整个路网而言,设置公交专用道后对交叉口行驶工况的排放改善要比其他路段的改善效果更为明显。Traffic congestion and environmental pollution are the limiting factors for the stable development of urban traffic.In order to study the influence of urban bus lane setting on motor vehicle exhaust and traffic flow,the quantitative simulation model of the influence of bus lane emission on motor vehicle exhaust emission was established by using traffic simulation system VISSIM and exhaust gas model MOVES.The paper takes the South Gate to TV tower of Xi'an as the research object,three different bus lanes were designed for the study including central bus lanes,curbe bus lanes and no bus lanes.The results show that setting the bus lane after the entire road network all the total emissions of motor vehicles have been significantly improved,the exhaust emissions from the central bus lanes are the least,the second of curb bus lanes,no bus lanes for maximum emissions.For the entire road network,setting the bus lane after the intersection of driving conditions to improve emissions than the other sections of the improvement effect is more obvious.
