摘　　要：利用车载尾气检测设备(PEMS)OEM-2100收集了在交叉口和路段上的实时尾气排放数据,利用GIS和相应二次开发工具构造了排放数据的分析平台,提出了交叉口尾气排放的空间分析方法,并对所收集的数据进行了对比分析。在此基础上,得到了交叉口处车辆各转向下的不同排放物的排放特征,计算了交叉口各转向相对于路段的排放系数,并对PEMS技术交叉口尾气排放进行了探讨。This paper uses the portable emission measurement system（PEMS） OEM-2100 to collect the realtime vehicle emission data at intersections as well as on the road, and develops the analysis platform for the emission data based on GIS and corresponding secondary developing tools. The paper provides a spatial analysis method for emissions at intersections, and conducts a comparative analysis to the collected data. Further, the emission characteristics of different emission species for different vehicles＇ turning movement at intersections are obtained, and the ratio of emissions for each turning movement to the emissions on the road is calculated. Finally, the paper presents a discussion with respect to further analysis of emissions at intersections based on PEMS.
