EVALUATION AND COMPARISON OF THREE AIR POLLUTION PREDICTION MODELS

This paper presents a brief discussion of the theoretical and mathematical development of a line-source dispersion model AIRPOL-4 designed by the Virginia Highway and Transportation Research Council to eliminate some of the problems encountered with existing models. It also comparatively evaluates the predictive and cost performances of AIRPOL-4 with those of the California Division of Highways and the U.S. Environmental Protection Agency models. The predictive performances of these models are evaluated, against measured data, in relation to wind speed, road-wind angle, atmospheric stability class, source height, and receptor location. The results demonstrate that the predictive capability and reliability of AIRPOL-4 are generally superior to those of the other models. Comparison of cost performances for the models is based on operating costs determined for each of the models for air quality analyses involving identical input parameters. The results of this cost comparison demonstrate that AIRPOL-4 is significantly more cost effective than either of the other models.
