METHODOLOGY OF THE KENTUCKY INCREMENTAL ANALYSIS

PROBLEMS CONFRONTED IN THE KENTUCKY INCREMENTAL ANALYSIS WERE DISCUSSED. THE STANDARDS BY WHICH KENTUCKY ROADS WERE CLASSIFIED FOR INCREMENTAL STUDY WERE DESIGNATED AND POSSIBLE ALTERNATIVES FOR HANDLING ISSUES RELATED TO THE INCREMENTAL TREATMENT OF MAINTENANCE COSTS WERE GIVEN. TRAFFIC COUNTS WERE USED TO ESTABLISH BOTH THE VOLUME AND COMPOSITION OF PRESENT TRAFFIC AND TO PROVIDE A BASIS FOR PROJECTING THEM TO THE PROGRAM YEAR. COUNTS WERE MADE IN INCORPORATED CITIES IN THE STATE AND WERE TRANSLATED INTO VEHICLE MILEAGE TOTALS BY COMPUTATIONS. IF THE CITIES OF OVER 5,000 POPULATION WERE SEPARATED INTO FAIRLY HOMOGENEOUS GROUPS, A HIGH DEGREE OF RELATIONSHIP COULD BE FOUND BETWEEN TOTAL VEHICLE MILEAGE, POPULATION, AND MILES OF STREET. THE PROPORTION OF HIGHWAY EXPENDITURES PROPERLY CHARGEABLE AGAINST HIGHWAY USERS WAS ANOTHER PROBLEM. THE PATTERN OF USER RESPONSIBILITY COULD BE BEST ESTABLISHED BY MAKING AN ASSIGNMENT BASED UPON TOTAL EXPENDITURES. ORIGIN AND DESTINATION STUDIES WERE USED TO SEPARATE THE RESPONSIBILITY IN EACH REGISTERED WEIGHT CATEGORY INTO THAT ATTRIBUTABLE TO DOMESTIC AND TO FOREIGN VEHICLES. A STRUCTURE OF PER VEHICLE RESPONSIBILITY WAS ESTABLISHED BY VEHICLE TYPE AND REGISTERED WEIGHT WHICH DEPENDED SOLELY UPON THE EXPENDITURE REQUIRED BY THE VEHICLE'S USE OF THE HIGHWAYS, AND WHICH COULD BE REDUCED TO A PERCENTAGE BASIS AND APPLIED TO THE REVENUE WHICH THE STATE MUST OBTAIN FROM DOMESTIC USERS. A PLAN WAS DEVELOPED THAT PROVIDED GROUNDS FOR APPORTIONING THE AUTOMOTIVE SAFETY FOUNDATION PROJECTION OF MAINTENANCE COSTS AMONG TRAFFIC VOLUME SYSTEMS AND ALLOWED A COMPARISON OF MAINTENANCE COSTS ON ROADS SECTIONS HAVING SIMILAR CONDITIONS OF BASE AND SURFACE, AND APPROXIMATELY THE SAME TOTAL TRAFFIC, BUT DIFFERENT AXLE-LOAD DISTRIBUTIONS.
