Decision makers recognize that traffic forecasts aresometimes based on assumptions that may not berealized. They should be provided with tools that canhelp them to evaluate and select robust projects, nomatter which future scenario materializes. There is aneed to assess the risk of development occurring ornot occurring, or development occurring at onelocation rather than another. Due to uncertainties inforecasting future transportation facilities, projectevaluation procedures should be flexible enough toaccommodate changing outcomes as they develop. Thisbook develops a procedure based on RobustnessAnalysis techniques and uses an illustrative examplein demonstrating the use of the methodology inproject selection as it pertains to urbantransportation planning. It has an advantage ofmaking planning decisions more flexible byaccommodating possible future surprises andminimizing the uncertainties of using the results oftravel demand models. Robust projects will alwaysperform better for a variety range of differentfuture scenarios. Such projects are expected toperform well even if the assumptions made at theplanning horizon will not well be met in the future.
