Abstract

Motor vehicle emission factors for application in traffic/transport models are often estimated indirectly, through measurements of pollutant concentrations in the close vicinity of a road link. Such an approach provides insight into total vehicle fleet emissions on that link. However, estimation of emission factors from the measured concentration raises a set of complex issues. The concentrations depend not only on the emission factors, but also to a large degree on meteorological factors, as well as on the topography of the area. Using the number/mass balance model, a theoretical relationship was d
