• Abstract:
  A considerable amount of pollution to the air in the forms of hydrocarbons, carbon ; monoxide (CO), nitrogen oxides (NOx), particulate matter (PM) and air toxics comes ; from the on-road mobile sources. Estimation of the emissions of these pollutants and ; quantification of the pollutants released are the most important initial steps in the ; process of controlling the air pollution. This study presents a methodology to rank the ; roads based on the On-Road Mobile Source Air Pollutant (ORMSAP) emissions using ; self organizing maps (SOM). This methodology was applied in a case study in Ohio with ; the historic Average Annual Daily Traffic (AADT) data for highways. This data was ; obtained from Ohio Department of Transportation (ODOT) and the ORMSAP emission ; estimates were computed from Motor Vehicle Emission Simulator (MOVES). Traffic was ; considered as of two types of vehicles, gasoline powered passenger vehicles and diesel ; powered commercial trucks driven on three types of highways, interstate route, state ; route and US route. Five ORMSAPs -CO, NOx, PM10, PM2.5 and SO2- were taken into ; account in this study. Ohio highway network was classified into groups based on five ; ORMSAP emissions per road length and also per road segment. Ohio counties were ; classified according to the total ORMSAP emissions per county and also ORMSAP ; emissions per highway length, per capita and per area of the county. The results were ; visualized with the GIS maps.
