AIR QUALITY MANUAL: VOL IV. MATHEMATICAL APPROACH TO ESTIMATING HIGHWAY IMPACT ON AIR QUALITY
HIGHWAY ENGINEERS MUST PLAY AN IMPORTANT ROLE IN THE ENHANCEMENT AND PROTECTION OF THE ENVIRONMENT. THEY WILL HAVE TO CONSIDER A VARIETY OF FACTORS IN THE ENVIRONMENTAL IMPACT OF ANY HIGHWAY PROJECT AND COMPLETE A NUMBER OF STUDIES PRIOR TO WRITING AN IMPACT STATEMENT. ONE OF THESE STUDIES IS CONCERNED WITH THE GATHERING OF FIELD DATA, ANALYSIS OF SUCH DATA, AND WRITING AN AIR QUALITY REPORT. THIS MANUAL EXPLAINS A METHOD OF PREDICTING POLLUTANT CONCENTRATIONS WITHIN AN AREA OF STUDY WITH AND WITHOUT THE NEW HIGHWAY. THE PREDICTION ANALYSIS INCLUDES BOTH THE HIGHWAY CORRIDOR AND THE MESOSCALE. THE HIGHWAY CORRIDOR IS DEFINED AS A REGION EXTENDING FROM THE POINT WHERE THE POLLUTANTS ARE GENERATED BY TRAFFIC (THE HIGHWAY) DOWN WIND TO THE POINT WHERE AMBIENT POLLUTANT LEVELS ARE AGAIN REACHED. THE MESOSCALE AREA IS DEFINED AS THE AREA THROUGHOUT WHICH TRAFFIC VOLUMES ON THE SURFACE TRAFFIC NETWORK ARE SIGNIFICANTLY AFFECTED BY THE CONSTRUCTION OF A NEW HIGHWAY. /FHWA/
