Project: TRAMAQ-Sources of Particulates

Reference: UG250

Last update: 09/09/2003 11:56:12


The main objective of this project is to assess the contribution of roadside dust and other suspended particulates towards the levels of particulates measured at roads; and make comparisons with particle fractions emitted from engines.


The project will improve knowledge of the sources of urban airborne particulate matter and will ascertain the impact of vehicular traffic on the levels of particulate matter observed in urban locations. It is intended to assess the contribution of vehicles to roadside concentrations, including primary emissions and resuspended dust. Measurements of particulate matter concentrations, in a variety of different traffic environments, will be carried out. The results will be disseminated by reports and technical papers and if appropriate Traffic Advisory Leaflets.
