• Abstract:
  Air quality measurements were made at two street intersections in Texas. Measurements of carbon monoxide and meteorological information were made at several heights both upwind and downwind of the intersections. In addition, detailed traffic information was also recorded. Tracer gas studies using SF sub 6 were performed at both sites and at the Texas A&M University Research Annex. The one-hour average CO level was usually in the range of 2 to 6 ppm and the maximum instantaneous values were about 20 to 30 ppm. The SF sub 6 results were found to be scattered due primarily to the low number of passes with the release vehicle. Aerosol samples at the two sites showed a maximum value of about 140 microgram/cu M for a 60-to-8-hour average. An air quality model called TEXIN for street intersections was developed in conjunction with FHWA Project 541. The model incorporates the MOBILE-2 and CALINE-3 computer programs with a set of established "short-cut" traffic and excess emission techniques.
