EFFECT OF ROAD DESIGN ON FUEL CONSUMPTION RATE OF A TYPICAL MOTOR TRUCK

THE EFFECT OF SPEED, ROAD GRADIENT, SURFACE TYPE, CURVATURE, AND SPEED VARIATION ON FUEL CONSUMPTION OF A TYPICAL DELIVERY TRUCK HAVING A GROSS VEHICLE WEIGHT OF 16,400 LB WAS INVESTIGATED. CARE WAS TAKEN TO AVOID DISTORTION OF RESULTS DUE TO VARIATIONS IN AIR TEMPERATURE, DRIVER OPERATING HABITS, AND WIND CONDITIONS. THE PHOTOELECTRONIC FUELMETER DEVELOPED AT CATHOLIC UNIVERSITY WAS USED FOR FUEL MEASUREMENTS. EIGHT TABLES WITH INFORMATION ON TRUCK FUEL CONSUMPTION RATES AS RELATED TO A PARTICULAR HIGHWAY FACTORS WERE PRESENTED. OPTIMUM TRUCK FUEL CONSUMPTION WAS FOUND TO BE OBTAINED FOR A SPEED OF 14 MPH ON A LEVEL STRAIGHT HIGH-TYPE SURFACE /0.0786 GAL MI/. ROAD GRADIENT WAS SHOWN TO BE AN IMPORTANT FACTOR IN DETERMINING FUEL CONSUMPTION RATES. TRUCK FUEL CONSUMPTION ON A 10% GRADE AT 14 MPH, FOR EXAMPLE, WAS 0.4872 GAL/MI AS COMPARED TO 0.0786 GAL-MI ON LEVEL ROUTES AT THIS SPEED. TABLES DEVELOPED MAY BE USED TO DETERMINE THE EFFECTS OF HIGHWAY IMPROVEMENTS ON TRUCK OPERATING COSTS.
