COST-EFFECTIVENESS IN ROUTE LOCATION PLANNING

The social, economic and environmental implications of constructed rights-of-way have led to development of route benefit-cost theories and optimum path algorithms. While most planning situations require a trade-off between the desired benefits and the available funding resources, techniques to determine the cost-effectiveness of alternative paths have not been developed. This paper discusses the a posteriori implications of the decision to fund a basic need and then consider the allocation of additional financial resources to enhance the plan. In route planning this means that a number of solutions having some secondary benefits, such as reduced negative impacts, may be acceptable alternatives to the minimum cost-low benefit plan. By introducing the concept of a plan benefit premium it is possible to model the decision maker's monetary value of benefits and structure a range of alternatives on a cost-effectiveness basis. The method is presented in linear programming format based on network analysis. By relaxing the cost constraint a series of local optimum benefit solutions can be compared. The uniqueness of the monotonic increase in local optimum values permits a simplified means of identifying the global optimum solution. /Author/TRRL/
