AN INVESTMENT APPROACH TOWARD DEVELOPING PRIORITIES IN TRANSPORTATION PLANNING

THIS PAPER DISCUSSES THE DEVELOPMENT OF PRIORITIES IN TRANSPORTATION PLANNING AS A PROBLEM IN INVESTMENT PLANNING OR CAPITAL BUDGETING. DETERMINATION OF A CONSTRUCTION PROGRAM FOR A REGIONAL FREEWAY NETWORK IS USED TO ILLUSTRATE THE APPROACH. THIS ANALYSIS IS CARRIED OUT WITH TWO MATHEMATICAL PROGRAMMING FORMULATIONS; ONE FORMULATION PERMITS EARLY ACQUISITION OF RIGHT-OF-WAY, AND THE OTHER DOES NOT. IN THESE FORMULATIONS, THE OBJECTIVE IS TO ORDER CONSTRUCTION OF SEGMENTS OF THE NETWORK SO THAT THE NET USER BENEFITS OF THESE FREEWAY SEGMENTS ARE MAXIMIZED. THE MAXIMIZATION OF THIS OBJECTIVE IS SUBJECT TO SEVERAL CONSTRAINTS. EXPENDITURES ON THE FREEWAY SEGMENTS ARE LIMITED BY THE BUDGET ALLOCATED FOR THAT PURPOSE, AND THE ENITRE NETWORK MUST BE COMPLETED BY A PARTICULAR DATE. THE RESULTS OF THE ANALYSIS PERMIT ESTABLISHMENT OF PROJECT PRIORITIES AND OF A CONSTRUCTION PROGRAM FOR COMPLETING THE NETWORK IN A PARTICULAR LENGTH OF TIME. A SIGNIFICANT ADVANTAGE OF THE USE OF MATHEMATICAL PROGRAMMING TECHNIQUES IN THIS INVESTIGATION IS THE EASE WITH WHICH SENSITIVITY ANALYSES CAN BE ACCOMPLISHED; THE IMPACT OF ALTERNATE BUDGETS AND VARYING LENGTHS OF TIME TO CONSTRUCT THE FACILITIES CAN BE READILY DETERMINED. /AUTHOR/
