MODEL FOR FUNDS ALLOCATION FOR URBAN HIGHWAY SYSTEMS CAPACITY IMPROVEMENTS

MOST AGENCIES, IN CONSIDERING THE ALLOCATION OF FUNDS FOR HIGHWAY AND STREET IMPROVEMENTS AMONG POSSIBLE ALTERNATIVES, MAKE SOMEWHAT ARBITRARY DECISIONS BASED ON SUFFICIENCY RATINGS, ENGINEERING JUDGEMENT, OR SOME OTHER EMPIRICAL CRITERION. THESE METHODS FOR ALLOCATING FUNDS DO NOT CONSIDER THE EFFECT OF PARTICULAR IMPROVEMENTS ON THE SYSTEM AS A WHOLE, NOR DO THEY CONSIDER THE EFFECT ON THE TOTAL SYSTEM COSTS OF CONGESTION ON PARTICULAR LINKS. A FEASIBLE METHOD OF ALLOCATING FUNDS FOR HIGHWAY IMPROVEMENTS IN A MANNER THAT WILL YIELD A MINIMUM TOTAL COST FOR THE ENTIRE SYSTEM, CONSIDERING THE TOTAL COSTS OF OPERATING VEHICLES /TIME, ACCIDENT, AND OPERATING COSTS/ ON ALL LINKS OF THE NETWORK, PLUS THE TOTAL COSTS FOR MAKING IMPROVEMENTS TO VARIOUS LINKS THROUGHOUT THE SYSTEM, IS INTRODUCED IN THIS PAPER. THE FINAL OBJECTIVE IS TO PROVIDE THAT TRANSPORTATION SYSTEM FOR THE REGION WHICH WILL COST LEAST TO BUILD AND USE. THE REPORT IS DIVIDED INTO THREE SECTIONS WHICH INCLUDE /1/ THE USE OF THE MODEL, /2/ FORMULATION OF THE MODEL, AND /3/ SOME RELATED MODELS. IN THE LAST SECTION, THREE OTHER EXAMPLES OF THE USE OF LINEAR PROGRAMMING MODELS TO DETERMINE THE OPTIMUM ALLOCATION OF FUNDS FOR HIGHWAY IMPROVEMENTS ARE DISCUSSED. IN PARTICULAR, THE PROBLEM OF THE SHIPMENT OF COMMODITIES BETWEEN URBAN CENTERS OVER A REGIONAL OR NATIONAL HIGHWAY NETWORK IS EXAMINED. AN APPENDIX PRESENTS THE MATHEMATICAL DEVELOPMENT OF AN EFFICIENT SOLUTION TECHNIQUE FOR THE MODEL DEVELOPED, TOGETHER WITH A SOLUTION OF AN EXAMPLE PROBLEM.
