USE OF SUFFICIENCY RATINGS IN LONG-RANGE PLANNING

THE DEVELOPMENT OF A LONG-RANGE PROGRAM USING SUFFICIENCY RATINGS IS DISCUSSED AS A SIMPLE PROCESS, ASSUMING THAT COST ESTIMATES FOR CONSTRUCTION PROJECTS ARE AVAILABLE. A SUFFICIENCY RATING CUT-OFF POINT MUST BE ESTABLISHED. THE CUT-OFF POINT IS THE POINT BELOW WHICH ROAD SECTIONS ARE INADEQUATE FOR PROPER SERVICE TO MOTOR TRANSPORTATION. ALL ROAD SECTIONS HAVING SUFFICIENCY RATINGS BELOW THIS POINT ARE PLACED IN THE CATEGORY OF URGENT NEEDS. IN SCHEDULING THE CORRECTION OF URGENT NEEDS OVER A PERIOD OF TEN YEARS, IT MUST BE RECOGNIZED THAT ADDITIONAL DEFICIENCIES WILL DEVELOP DURING THIS PERIOD. IT IS POSSIBLE TO ESTIMATE WHAT ALLOWANCE MUST BE MADE FOR THESE ITEMS AND TO ADD IT TO PRESENT URGENT NEEDS, TO COME UP WITH A TOTAL COST ESTIMATE REPRESENTING THE CONSTRUCTION PART OF A LONG RANGE PROGRAM. TO THIS MUST BE ADDED REQUIREMENTS FOR MAINTENANCE AND ADMINISTRATION TO OBTAIN TOTAL COST FOR PRESERVING AND DEVELOPING A HIGHWAY SYSTEM. ALTERNATIVE PROGRAMS, CONTINUING REVIEW AND PUBLIC UNDERSTANDING ARE DISCUSSED.
