METHODOLOGY FOR THE DETERMINATION OF EMISSION LINE SOURCES

The study of automotive vehicle pollution in a metropolitan area requires accurate reporting of emissions. This depends on efficient monitoring of traffic flow, and knowing the location parameters critical to the emission process, and adequate knowledge of vehicular emissions under a range of operating conditions. This report describes the development of a methodology which documents the criteria for determining which major freeway and arterial links should be considered emission line sources in a metropolitan area. In addition to developing the methodology, it is used in the St. Louis Air Quality Control Region, to determine specifically what links shall be considered as line sources.
