VALIDATION AND APPLICATIONS OF URBAN DIFFUSION MODEL FOR VEHICULAR POLLUTANTS
A PRACTICAL, MULTIPURPOSE URBAN DIFFUSION MODEL (APRAC-1A) HAS BEEN DEVELOPED AND EVALUATED FOR PREDICTING CONCENTRATIONS OF INERT, VEHICLE-GENERATED POLLUTANTS. THE MODEL REQUIRES ONLY ROUTINELY AVAILABLE METEOROLOGICAL AND TRAFFIC DATA TO GIVE THE FOLLOWING OUTPUTS: AERIAL CONCENTRATION ISOPLETHS, SEQUENTIAL HOURLY POINT VALUES, AND FREQUENCY DISTRIBUTIONS. AN EXTENSIVE FIELD EXPERIMENT WAS CONDUCTED IN SAN JOSE TO EVALUATE AND REFINE ALL COMPONENTS OF THE MODEL. A STREET EFFECTS SUBMODEL WAS DEVELOPED TO ACCOUNT FOR THE HIGH CONCENTRATIONS AND LARGE GRADIENTS OBSERVED IN URBAN STREET CANYONS. /AUTHOR/
