TWO PROCEDURES TO IMPROVE THE ECONOMIC EVALUATION OF ALTERNATIVE HIGHWAY SYSTEMS

AN INTEGRAL PART OF ANY COMPREHENSIVE TRANSPORTATION PLANNING STUDY IS THE ECONOMIC EVALUATION OF FUTURE ALTERNATIVE HIGHWAY SYSTEMS. A DISCUSSION OF TWO PROCEDURES IS PRESENTED TO IMPROVE THE METHOD OF ECONOMIC EVALUATION THAT IS GENERALLY USED TODAY. THIS FIRST CONSIDERS PEAK AND OFF-PEAK TRAVEL TO OBTAIN IMPROVED SYSTEM MEASURES FOR THE USER COST QUANTIFICATION. THE SECOND UTILIZES A RANGE OF UNIT TIME VALUES AND INTEREST RATES TO ENABLE THE DECISION- MAKER TO EVALUATE MORE EFFECTIVELY THE SIGNIFICANCE OF THESE TWO VARIABLES IN THE ECONOMIC EVALUATION. THE PROCEDURES ARE DEMONSTRATED THROUGH THE USE OF ECONOMIC ANALYSES CONDUCTED FOR TWO MEDIUM-SIZED URBAN AREAS: ERIE, PA., AND WATERLOO, IOWA. IMPROVEMENTS ARE SUGGESTED IN SYSTEM MEASURES TO REFLECT TRUE INTERSECTION DELAYS AND IN THE DETERMINATION OF A VALUE FOR TIME THAT IS REPRESENTATIVE OF THE REAL COSTS INCURRED BY TRIP MAKERS. /AUTHOR/
