AIR POLLUTION AND ROADWAY LOCATION, DESIGN AND OPERATION PROJECT OVERVIEW

This report gives an overview of an air quality study to establish an extensive data base for primary pollutants emitted from freeways of various configurations, at-grade, depressed and elevated in the Los Angeles Basin. The freeway locations selected for study were in areas carrying extremely high volumes of traffic. Meteorological data were obtained for inclusion in the data base. A line source microscale model to predict the dispersion of pollutants, CALINE 2, was developed, validated, and improved under this project. Two mobile air quality research laboratories were constructed and utilized for this project. Air pollutants sampled include carbon monoxide (CO), reactive and unreactive hydrocarbons (RHC, URHC), oxides of nitrogen (NOx), ozone (O3), sulpur dioxide (SO2), and hydrogen sulfide (H2S). Traffic volume data were obatined. Particulate sampling was conducted to obtain total particulates, lead, and various other elements.
