VEHICLE EMISSIONS SURVEILLANCE STUDY

THE OBJECTIVE WAS TO RECOMMEND OPTIMAL PROCEDURES FOR CONDUCTING AN AUTOMOBILE EXHAUST EMISSIONS FIELD SURVEILLANCE PROGRAM. THE PRIMARY OBJECTIVE OF THIS FIELD SURVEILLANCE PROGRAM IS TO CHARACTERIZE VEHICULAR EMISSIONS TO THE ATMOSPHERE FOR SPECIFIC REGIONS WITHIN THE UNITED STATES. ALTERNATIVELY, THE DATA MAY BE USED TO EVALUATE REGIONAL DIFFERENCES IN VEHICULAR EMISSIONS SUCH AS MIGHT OCCUR BECAUSE OF DIFFERENT VEHICLE MAINTENANCE POLICIES. GENERAL SURVEILLANCE PROGRAM GUIDELINES WERE DEVELOPED BUT WERE NOT AMENABLE TO MATHEMATICAL MODELING BECAUSE OF COMPLEXITY AND/OR LACK OF DEFINITIVE DATA. SPECIFIC PROCEDURES AND EQUIPMENT CONFIGURATIONS WERE OPTIMIZED USING THE SURVEILLANCE SYSTEM MODEL. /AUTHOR/
