THE ECONOMY OF HIGHWAY IMPROVEMENTS

IN ESTIMATING THE ECONOMY OF CONTEMPLATED ROAD IMPROVEMENTS, THE QUESTION, "HOW MUCH CAN WE AFFORD TO INVEST NOW TO SAVE A DETERMINED AMOUNT OF ANNUAL EXPENSE?" CAN BE ANSWERED BY COMPARING THE ADDITIONAL INVESTMENT WITH THE SAVING IN COST WHICH IT EFFECTS. THIS METHOD OF COMPUTING ECONOMY IS ILLUSTRATED IN DETAIL BY A PROJECT FOR IMPROVING A GRAVEL ROAD BY SURFACING IT WITH CONCRETE. FOR THE COST DATA ASSUMED IT IS SHOWN THAT THE IMPROVEMENT IS JUSTIFIED FOR AN ANNUAL TRAFFIC OF 200,000 VEHICLES OR MORE, BUT THAT FOR 100,000 VEHICLES IT DOES NOT APPEAR TO BE ECONOMICAL. THE COMPUTATION SHOWS THAT THE SAVING IN ANNUAL ROAD COST IS RELATIVELY SMALL IN COMPARISON WITH THE SAVING IN VEHICLE OPERATING COST WHEN THE ANNUAL TRAFFIC IS LARGE. INDEED AN APPROXIMATE ECONOMY DETERMINATION CAN BE MADE BY CONSIDERING THE VEHICLE COST ONLY. /AUTHOR/
