A COST-BENEFIT EVALUATION OF TRANSPORTATION CORRIDORS

THE TRANSPORTATION CORRIDOR APPROACH TO PLANNING TRANSPORTATION IS A MIXTURE OF 3 BASIC IDEAS: BUYING LAND EARLY, BUYING MORE LAND THAN IS NEEDED FOR INITIAL TRANSPORTATION FACILITIES, AND BUYING MORE LAND THAN WILL BE NEEDED FOR TRANSPORTATION ALONE. THE LAND IS HELD IN A LOWER LEVEL OF USE THAN WOULD OTHERWISE DEVELOP SO THAT TRANSPORTATION COSTS ARE REDUCED AND EFFICIENT LAND USE IS PROMOTED. THE RELEVANT COSTS FOR COST-BENEFIT ANALYSIS ARE THE ECONOMIC COSTS OF ACQUIRING AND HOLDING LAND. THE MAIN BENEFITS ARE SAVINGS IN COSTS. INDIRECT AND INTANGIBLE COSTS AND BENEFITS CAN BE EXPECTED BECAUSE OF THE IMPACT OF TRANSPORTATION ON LAND USE. THE NATURE OF COSTS AND BENEFITS AND POSSIBLE METHODS FOR MEASUREMENT ARE DESCRIBED IN THE PAPER. A BENEFIT-COST MODEL IS THEN DESCRIBED BY WHICH THE ESSENTIAL QUESTIONS OF HOW MUCH LAND TO BUY, AND WHEN, CAN BE EVALUATED. THE MAXIMUM TANGIBLE NET BENEFIT FROM THE CORRIDOR APPROACH TO TRANSPORTATION PLANNING WILL BE ATTAINED BY BUYING LAND WHEN THE COST OF DELAYED ACQUISITION IS RISING MORE RAPIDLY THAN THE COST OF EARLY PURCHASE. THIS SIMPLE RELATIONSHIP IS THE HEART OF THE CORRIDOR CONCEPT. /AUTHOR/
