摘　　要：为了寻求更加精确的道路车辆排放模型的建立方法,对道路车辆排放关键因素受路段参数的影响进行探索。通过实验方法测算机动车排放因子,并获取路段平均速度、路段平均加速度、路段平均VSP三个动态特征参数,路段长度和道路等级两个路段静态特征参数,通过回归分析的方法量化不同因素与机动车排放因子的关联关系。结果表明:道路特征参数对机动车各类污染物的排放因子均有一定程度的影响,但单一因素对道路排放因子的影响程度有限。In order to find the way to build emission model which has higher accuracy, this paper tries to fully explore the influence of emission intensity and road parameters. By a lot of tests to obtain data such as average road speed, average road accelerated speed, average road VSP, emission intensity, road length, road type, and then established a relationship model to quantify the relationship between these factors. The experimental results show that the single parameter has a little influence on the emission intensity within certain range, however both dynamic characteristic parameters and static parameters could impact emission intensity.
