INVESTMENT ANALYSIS BY COMPUTER METHODS FOR THE STATE TRUNK HIGHWAY SYSTEM IN WISCONSIN. PART 1' METHODOLOGY FOR COMPUTING REMAINING INVESTMENTS

THE MAIN PURPOSE OF A HIGHWAY NEEDS STUDY IS TO DETERMINE THE MAGNITUDE AND COSTS OF A PROGRAM NEEDED TO OVERCOME DEFICIENCIES IN A PARTICULAR HIGHWAY SYSTEM AND ATTAIN ADEQUACY WITHIN A DESIRED PERIOD OF YEARS. THE SO-CALLED INVESTMENT ANALYSIS APPROACH ESTABLISHES NEEDS FROM THE RELATIONSHIP THAT EXISTS BETWEEN HIGHWAY INVESTMENTS REMAINING IN SERVICE AND TRAVEL REQUIREMENTS. ONE OF THE MAJOR TASKS IN ESTIMATING NEEDS USING THE INVESTMENT ANALYSIS APPROACH IS THE DETERMINATION OF INVESTMENTS REMAINING IN SERVICE. ROAD LIFE AND COST RECORDS HAVE BEEN THE GENERAL SOURCE OF SUCH COMPUTATIONS. DIFFICULTIES, HOWEVER, HAVE BEEN ENCOUNTERED IN THE PAST MAINLY BECAUSE OF THE INADAPTABILITY OF EXISTING PROCEDURES TO MODERN COMPUTER TECHNIQUES. OUTDATED METHODS OF RECORD-KEEPING AND ANALYSIS HAVE PREVENTED NEW DEVELOPMENTS IN THE FIELD OF ROAD LIFE AND INVESTMENT STUDIES AND HAVE LED TO THE BELIEF THAT SUCH STUDIES ARE CUMBERSOME AND OF LITTLE VALUE TO THE HIGHWAY ADMINISTRATORS. AS A STEP TOWARD THE OVERALL REVIVAL OF ROAD LIFE AND INVESTMENT STUDIES, IS THE REEVALUATION OF EXISTING TECHNIQUES FOR THEIR INCORPORATION INTO COMPUTER OPERATIONS. METHODOLOGY IS DEVELOPED FOR THE AUTOMATIC COMPUTATION OF REMAINING INVESTMENTS OR COSTS IN HIGHWAYS. REPLACEMENT OF TEDIOUS MANUAL COMPUTATIONS IS INTENDED. WISCONSINS BACKLOG OF MORE THAN TWENTY YEARS IN REMAINING COST RECORDS FOR THE STATE TRUNK HIGHWAY SYSTEM HAS BEEN ELIMINATED USING THIS NEW PROCEDURE. POSSIBILITIES HAVE BEEN CREATED FOR THE EVALUATION OF HIGHWAY NEEDS ON A 100 PERCENT SAMPLE BASIS.
