Abstract:

Air Quality measurements along Texas freeways have been completed at six sites, representing "at grade", "elevated", and "cut" roadbed configurations, and representing "coastal plain", "inland plain", "hill country", and "mountain" climates in Texas. Measurements at each site consisted of carbon monoxide concentrations at ten downwind. and two upwind locations, vehicle length, count, and speed by lane, and detailed wind speed, wind direction, temperature, relative humidity, and solar radiation between five and 100 feet. Nitrogen oxide concentrations at four downwind and one upwind station were also measured at selected sites. The instruments were interfaced to a Data General NOVA 1200 minicomputer, allowing effectively simultaneous recording of all instruments. The resulting data were logged on magnetic cassette and later transferred to standard nine track tape. Hydrocarbons were also measured at some sites, being recorded on chart recorders and later transferred to tables included in this report.
