Abstract: The importance of choosing appropriate objectives to be used in the evaluation of alternative transportation plans is examined. A practical technique designed to help analysts choose objectives is presented. The technique is based upon calculating, using estimates of impacts and preferences, an upper bound on the expected effect on the results of an evaluation of excluding each of the potential objectives from consideration in the evaluation. An application of this screening model to a route location study conducted by the Ontario Ministry of Transportation and Communications is presented to ilustrate the model's practicality and usefulness.
