INTERACTIVE SENSITIVITY ANALYSIS IN TRANSPORTATION PLAN EVALUATION

An experimental technique for exploring the sensitivity of transportation plan evaluations to forecasting and community value uncertainties is described. Three kinds of uncertainty - goal-achievement impacts, costs, and goal-weights - are included. Within a cost-effectiveness evaluation framework, an "on-line" capability for interactively and iteratively testing plan comparisons is outlined. A series of user-oriented computer instructions is developed to test plan comparison outcomes according to a wide variety of user-selected changes in impact forecasts, goal weights, and cost forecasts. A sample, hypothetical application of the technique is described. The technique is currently under further development by the San Diego region comprehensive planning organization. /Author/TRRL/ /TRRL/
