Analysis and Modeling of Air Quality at Street Intersections

Four roadway intersection air pollution models were compared to experimental data and evaluated. The models included the recently developed Texas Intersection Model (TEXIN), The Intersection Midblock Model (IMM), the program MICRO and the Indirect Source Guidelines. Data obtained by Texas A&M University at two intersections in Texas and by CALTRANS at an intersection in California were used for the evaluation. The TEXIN Model performed best in all comparisons to the data. The IMM was almost as accurate as TEXIN but required an order of magnitude more input information and computer time. MICRO and the Indirect Source Guidelines performed poorly.
