POSSIBLE AREAS OF IMPROVEMENT IN RATING PROCEDURES

ASPECTS OF SUFFICIENCY RATING SYSTEMS WHICH DEFEAT STANDARDIZATION ARE DISCUSSED. SOME OF THESE MENTIONED ARE: (1) THE DIFFICULTY OF OBTAINING CONSISTENCY, (2) PERSONAL JUDGEMENT WHICH REDUCES THE RELIABILITY OF THE RATING, (3) VARIATION OF STANDARDS USED FOR THE CONDITION OR STRUCTURAL ADEQUACY RATING, (4) MAINTENANCE ECONOMY RATINGS, AND (5) ELEMENTS FOR WHICH OBJECTIVE STANDARDS CANNOT BE ESTABLISHED. IT IS CONCLUDED THAT A TEST MUST BE MADE OF ANY SUFFICIENCY RATING BY COMPARING THE RATED SUFFICIENCY OF VARIOUS HIGHWAY SECTIONS WITH AN EVALUATION OF THEIR ACTUAL PERFORMANCE AS TRAFFIC CARRYING FACILITIES. ECONOMIC CONSIDERATIONS, SUCH AS COST, BENEFITS, AND EARNINGS MUST ALSO BE CONSIDERED.
