TRAPS 52 USER'S GUIDE--ANALYTICAL AND EXPERIMENTAL ASSESSMENT OF HIGHWAY IMPACT ON AIR QUALITY

TRAPS 52 is a simplified version of the TRAPS II air pollution dispersion model. This version has been designed to run on the Texas Instruments' SR52 hand held programmable calculator. The program calculates the carbon monoxide concentration at any distance downwind from a roadway, given site geometry, meteorology, and traffic parameters. The program is quite flexible, accepting inputs in either metric units, English units, or a mixture of both. Many error conditions are caught as soon as the parameter is entered and the parameter is rejected. If an error occurs later, a code indicating the most probable cause is returned. Meteorology and traffic parameters can be updated without changing the site geometry for running multiple cases at a single site.
