在OEM-2100基础上开发了一种机动车道路排放实时测试系统,并在实际道路上进行了轻型车的实时排放测试。计算了路段排放因子和排放总量,分析了车辆各行驶工况所占时间和排放量比例以及平均排放率,研究了各工况下机动车尾气污染物的贡献率,为准确测定交通流中单车污染物提供一种可行的方法。该测试系统为建立排放模型提供数据依据,对于评价交通控制改进措施和智能交通系统对排放的影响具有重要的意义。
On the basis of OEM-2100, a real-time road vehicle emission testing system was developed and real-time light vehicle emission testing was conducted on the actual road. The emission factor and the total emission of the road section are calculated. The proportion of the time and the discharge of each driving condition and the average emission rate are analyzed. The contribution rate of vehicle exhaust pollutants in each working condition is studied. In order to accurately measure the traffic flow Bicycle pollutants provide a viable approach. The test system provides the data basis for establishing the emission model and is of great significance to evaluate the traffic control improvement measures and the impact of ITS on emissions.
