| Abstract: | Air pollution levels in the vicinity of simple signalized intersections were investigated. A thorough review of the literature to locate suitable data bases was performed and a new, simplified predictive model was developed. The new model will be known as the Texas Intersection (TEXIN) Model and incorporates the MOBILE-2 and CALINE-3 computer programs with a set of extablished "short cut" traffic and excess emissions techniques' The result is an efficient computer program capable of estimating carbon monoxide levels near intersections (both signalized and unsignalized) gzven minimal geometrical, meteorological and traffic parameters. The TEXIN Model was compared to experimental cata near intersections and to corresponding simulations by the Intersection Midblock Model (IMM) and other existing intersection models. The TEXIN Model only requtres approxzmately ten percent of the inputs and computer time required by the Intersectzon Midblock Model. The new model also predicts pollution levels with better accuracy than the IMM and other existing intersection models. |
