Typical Criteria Used in the Evaluation of Transportation Alternatives
These 59 evaluation questions were included in the Draft Final Report of July 17, 2001 for the Central Area Loop Study in Cincinnati, Ohio. See the Skyloop website for a description. It was prepared for the Ohio Kentucky Indiana Regional Council of Governments by Parsons Brinckerhoff Quade & Douglass, Inc. It has been used to evaluate the four Central Area Loop technology alternatives included in this study. It can serve as a check-list for others doing similar alternatives analysis studies if modified to fit their particular circumstances.
