OPTIMAL RESOURCE ALLOCATION AND TOLL PATTERNS IN USER-OPTIMISED TRANSPORT NETWORKS

VERY GENERAL FORMULATION OF THE PROBLEM FACED BY ANY TRANSPORT PLANNING GROUP IS DISCUSSED: THAT OF OPTIMALLY ALLOCATING ITS ROAD IMPROVEMENT BUDGET TO AN EXISTING NETWORK SO AS TO MINIMIZE TRAVEL TIME AND CONGESTION FOR USERS OF THE NETWORK UNDER ITS JURISDICTION. IF CONGESTION TOLLS ARE RULED OUT AS A MEANS OF BURDENING TRAVELERS WITH THE COSTS THEY IMPOSE ON OTHERS, THEN THE DETERMINATION OF THE INVESTMENT PATTERN THAT MINIMIZES COSTS TO USERS PLUS A CAPITAL RENTAL CHARGE ON THE INVESTMENT ITSELF IS COMPUTATIONALLY INFEASIBLE. IF, ON THE OTHER HAND, INDIVIDUALS ARE FORCED TO EXPLICITLY CONSIDER THE IMPACT THEIR TRAVEL HAS ON OTHERS BY MEANS OF CONGESTION TOLLS, THEN THE CHOICE OF AN OPTIMAL INVESTMENT PATTERN BECOMES COMPUTATIONALLY FEASIBLE BY STANDARD MARGINAL PRODUCTIVITY METHODS. THE PROBLEM OF RESOURCE ALLOCATION IS PRESENTED IN THE CASE OF AN EXTREMELY SIMPLE NETWORK CONSISTING OF TWO PARALLEL LINKS CONNECTING A COMMON ORIGIN AND DESTINATION. THE FINAL SECTION THEN SHOWS THAT THE RESULTS SHOWN TO HOLD IN SIMPLE SYSTEMS HOLD FOR NETWORKS OF AN ARBITRARY DEGREE OF COMPLEXITY, AND DEALS WITH THE NECESSITY OF PATH, RATHER THAN LINK, TOLLS. /AUTHOR/
