Abstract：Floating car detection technology can collect data for single car, and the average speed in the data is continuous according to constant sampling interval. In view of this feature, a real-time emission model for light duty vehicles was established using road test data. In the process of modeling, one parameter of average speed increment (ASI) was applied to classify the average speed, and reflect emission changes under the same average speed. Compared with the test values, the calculation errors of the model are less than 10% for CO2, and are less than 15% for NOx, HC and CO. Further, a model application method was proposed, which can calculate the traffic exhaust pollutions in real time.
