Mobile source emissions inventory development. Final report
The study was undertaken to develop a methodology for preparing a 5km by 5km areal gridded mobile source emissions inventory for areas of Illinois which are in nonattainment status with regard to National Ambient Air Quality Standards. A pilot emissions inventory was developed by linking the USEPA mobile source emissions program (MOBILE4) with existing traffic data from the Illinois Department of Transportation's (IDOT) Highway Record Data Bank (HRDB), the Chicago Area Transportation Study (CATS) and Illinois Department of Energy and Natural Resources' (ENR) Geographic Information System (GIS). The methodology developed here was applied to one pollutant in one test case county in Illinois. Hydrocarbon emissions from mobile sources in Kane county are the focus of the study. Vehicle type, vehicle age, and Vehicle Miles of Travel (VMT) distributions were obtained from information provided in the 1982 Illinois State Implementation Plan (SIP). Among the products of the project is a preliminary 25-sq km gridded mobile source hydrocarbon emissions inventory for Kane county. Numerical results as well as a color correlated overview map of the county-wide gridded emissions inventory are provided in the report. Recommendations for improving the methodology and further developing gridded mobile source emission inventories for other Illinois counties are also provided.
