APPENDIX ON PROCEDURES-SUFFICIENCY-RATING FORMULAS

A REVIEW IS PRESENTED OF HIGHWAY SUFFICIENCY RATING PROCEDURES. REGARDLESS OF THE TYPE OF RATING FORMULA USED, THE PURPOSES FOR WHICH THEY WERE DEVELOPED WERE TO : (1) AID IN THE ASSIGNMENT OF PRIORITIES FOR RECONSTRUCTION BY EVALUATING THE RELATIVE ADEQUACY OF EACH HIGHWAY SECTION ACCORDING TO CERTAIN PRESCRIBED STANDARDS, (2) MINIMIZE OR ELIMINATE THE ELEMENT OF PERSONAL JUDGEMENT IN THE ASSIGMENT OF RATINGS, (3) EVALUATE THE ROAD SECTION'S ABILITY TO CARRY TRAFFIC SAFELY, RAPIDLY AND ECONOMICALLY, (4) HOLD TO A MINIMUM POLITICAL AND COMMUNITY PRESSURE IN HIGHWAY PLANNING AND CONSTRUCTION, (5) KEEP LEGISLATIVE OFFICIALS ADVISED AS TO THE CURRENT STATUS OF THE HIGHWAY PLANT AND THE FUNDS THAT ARE REQUIRED TO ACHIEVE A GIVEN STANDARD OF IMPROVEMENT ON A STATE-WIDE BASIS, (6) MEASURE AT ANNUAL INTERVALS THE AVERAGE RATING OF THE HIGHWAY SYSTEM SO THE RATE OF PROGRESS OF THE HIGHWAY PROGRAM CAN BE DETERMINED, AND (7) BUDGET FUNDS FOR HIGHWAY IMPROVEMENTS IN THE RELATIVE ORDER OF NEED, THUS PROTECTING THE PUBLIC'S INVESTMENT IN HIGHWAYS. THE WEAK AND STRONG POINTS OF THESE RATING METHODS ARE DISCUSSED. THE BUREAU OF PUBLIC ROADS MAINTENANCE AND INSPECTION RATINGS ARE DESCRIBED. THE SUFFICIENCY RATING PLAN CONSOLIDATED INTO ROUTE SECTIONS FURNISHES A MEANS OF RANKING THE SUFFICIENCY OF EACH SEGMENT OF THE HIGHWAY. IT ALSO FURNISHES A BASIS FOR THE PREPARATION OF MORE SCIENTIFIC MAINTENANCE BUDGETS AND A RECORD FOR FUTURE YEARS OF THE LOSS OR GAIN IN HIGHWAY PLANT REHABILITATION. A MANUAL WAS PREPARED WHICH IS NOW THE ACCEPTED GUIDE WITHIN THE BUREAU OF PUBLIC ROADS FOR MAKING MAINTENANCE INSPECTIONS OF FEDERAL-AID AND FOREST-HIGHWAY MILEAGE. A SUMMARY TABULATION IS PRESENTED OF SUFFICIENCY RATING PROCEDURES FOLLOWED BY NOTES TO THE TABULAR SUMMARY BY STATES DESCRIBING THE METHOD USED.
