Evaluation of European Road Transport Emission Models against on-road emission data as measured by optical remote sensing." The 17th International Conference "Transport and Air Pollution

A major on-road remote sensing emission measurement campaign was carried out in 2007 in Göteborg, Sweden, in order to provide on-road emission data for an evaluation of the three major road transport emission models in Europe, i.e. the COPERT 4 model, the Handbook of Emission Factors (HBEFA 2.1), and the recently developed ARTEMIS Road Model. The University of Denver’s latest generation remote sensing instrument, capable of measuring tailpipe concentrations of conventional remote sensing parameters CO, HC, NO and CO2, as well as new parameters NO2, NH3 and SO2, was used at four different sites representing different driving pattern and fleet compositions. In all, the on-road measurements comprised more than 15,000 vehicles. From license plate recognition, the remote sensing data could be allocated to individual vehicles of known age, Euro-class, size, fuel type, power, etc. For each site, average on-road emission factors
