Many transportation studies recommend improvements for some future design year (normally 20 years hence) and stage construction of these improvements by 5-year increments. Numerous methods have been used to stage recommended improvements, but only limited work has been done on developing procedures that optimize a special objective function for priority selection. One previous approach to to staging was to examine current capacity-deficient corridors and the target year volumes on the proposed facilities. Priorities were then set so that the facilities needed to relieve existing congestion were first, the facilities most heavily used in the future were next, and the less used future facilities were last. Another approach was to develop intermediate year travel forecasts from land use or traffic assignment models for intermediate years. The staging determination was similar to the full system evaluation process except that the intermediate year alternatives considered were combinations of projects composing the design year plan.
