STATISTICAL APPROACH TO ESTABLISHMENT OF MAINTENANCE LEVELS

THE USE OF STATISTICAL SAMPLING AND MULTIPLE LINEAR REGRESSION METHODS IS INCREASING WITHIN THE OHIO DEPARTMENT OF HIGHWAYS, PARTICULARLY IN REFERENCE TO MAINTENANCE COST STUDIES AND LEVELS OF SERVICE. THE FOUR FACTORS THAT INFLUENCE THE LEVEL OF SERVICE, AND THEREFORE ARE TO BE USED IN MEASURING THE QUALITY OF MAINTENANCE ARE: (1) THE PHYSICAL INTEGRITY OF THE ELEMENTS OF THE HIGHWAY; (2) THE SAFETY OF THE FACILITY FOR THE USER; (3) THE RIDEABILITY OF THE PAVEMENT; AND (4) THE AESTHETICS OF THE HIGHWAY. IN PLACE OF A DETAILED STUDY, THE TOTAL MAINTENANCE EFFORT WAS DIVIDED INTO EIGHT CATEGORIES OF ACTIVITY WITH THE INTENT TO ESTABLISH A METHOD FOR EVALUATING THE QUALITY OF MAINTENANCE IN EACH CATEGORY. AFTER EVALUATING EACH CATEGORY, WEIGHTING FACTORS BASES ON BROAD OBJECTIVES WILL BE APPLIED TO PRODUCE A SINGLE MEASURE OF MAINTENANCE QUALITY. THE EIGHT CATEGORIES BEING USED IN THE STUDY ARE: (1) ICE AND SNOW REMOVAL, (2) PAVEMENT MAINTENANCE, (3) SHOULDER MAINTENANCE, (4) VEGETATION CONTROL, (5) MAINTENANCE OF STRUCTURES, (6) ROADSIDES AND MEDIANS, (7) DRAINAGE, AND (8) APPURTENANCES.
