自動車排出ガスによる大気汚染予測に関する研究

(I) 拡散モデルの比較評価

抄録

This paper presents a comparison of four idealized line source dispersion models which include the EPA-HIWAY model, GM line source model, Tokyo Government model and Japan Environmental Agency's model. Each model validation was obtained by the regression analysis. In the analysis the model predictions were compared to measured NO_x concentrations.
The result of the model validation analysis shows that the EPA-HIWAY model has a tendency of over-estimated, but among the others, there are no large differences for the statistical evaluations.
