VEHICLE OPERATING COSTS ON BITUMINOUS, GRAVEL AND EARTH ROADS IN EAST AND CENTRAL AFRICA
A TWO-YEAR INVESTIGATION INTO VEHICLE OPERATING COSTS ON DIFFERENT TYPES OF ROAD SURFACE IN EAST AND CENTRAL AFRICA IS DESCRIBED. RESULTS COVER 65 BUSES AND FREIGHT VEHICLES ON 27 ROUTES. THE INVESTIGATION WAS CARRIED OUT TO PROVIDE DATA FOR ESTABLISHING PRIORITIES FOR ROAD IMPROVEMENTS AND DECIDING ON APPROPRIATE STANDARDS OF CONSTRUCTION. THE INVESTIGATION WAS NOT INTENDED TO PROVIDE ACTUAL COSTS OF OPERATION FOR COSTING PURPOSES. THE ITEMS OF OPERATING COST MEASURED WERE FUEL AND OIL, MAINTENANCE, TIRES, THE WAGES OF CREWS, AND DEPRECIATION. THE SUM OF THESE ITEMS IS ESTIMATED TO REPRESENT SOME 60 PERCENT OF TOTAL OPERATING COSTS. DATA FOR VEHICLE OPERATING COSTS WERE OBTAINED FROM A LARGE TRANSPORT CONCERN WITH ADEQUATE RESOURCES FOR MAINTENANCE AND OPERATING CONTROL. SMALL OPERATORS, WHO IN MANY COUNTRIES FORM THE BACKBONE OF THE TRANSPORT INDUSTRY, OFTEN USE SECOND-HAND VEHICLES AND HAVE MEAGRE RESOURCES, AND MAY WELL EXPERIENCE RELATIVELY GREATER COSTS ON POOR ROADS. THE USE OF THE RESULTS IN ESTIMATING THE VALUE OF ROAD IMPROVEMENT SCHEMES IS DISCUSSED AND A METHOD OF RECALCULATING THE COST RATIOS IS SUGGESTED FOR USE IN COUNTRIES WHERE THE UNIT COSTS OF LABOR AND MATERIALS ARE MARKEDLY DIFFERENT FROM THOSE IN EAST AND CENTRAL AFRICA. /AUTHOR/
