INFLUENCE OF VEHICLE DRIVING PATTERNS ON LOCALIZED URBAN EMISSIONS SOURCES

THIS PAPER PRESENTS PROCEDURES FOR CALCULATING THE EMISSIONS OF THE POPULATION-AVERAGE DIESEL- AND GASOLINE-FUELED VEHICLES IN A RANGE OF OPERATING MODES. THESE PROCEDURES, TOGETHER WITH A SIMPLE, BUT FLEXIBLE, MODEL OF VEHICLE DRIVING PATTERNS, ARE USED TO SHOW HOW CHANGES IN TRAFFIC FLOW AND DRIVING PATTERNS CAN INFLUENCE THE VEHICULAR SOURCE OF EMISSIONS ALONG URBAN ROADWAYS. THE PROCEDURES ARE APPLIED TO PREDICT EMISSION RATES IN HYPOTHETICAL TRAFFIC FLOWS AND IN REAL TRAFFIC CONDITIONS AS MEASURED IN CENTRAL EDINBURGH, SCOTLAND, WHERE THE RELATIVE CONTRIBUTIONS OF INDIVIDUAL TRAFFIC GROUPS TO THE VEHICULAR EMISSION COURCES HAVE BEEN ASSESSED.
