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.
