Abstract

Inaccuracy and bias in demand forecasts for transportation infrastructure projects have been well-documented and represent an obstacle to performance-based planning and programming. However, efforts to improve forecasting practice require clear answers to a number of open questions: Are there forecast characteristics in addition to accuracy that should also be maximized? How should forecast accuracy be measured? When is the right time to observe transportation demand for comparison to demand forecasts? Dr. Voulgaris presents a framework for evaluating forecast accuracy and shares the results of qualitative and quantitative research that can inform clearer evaluation of transportation forecasts.
