Multicriteria analysis in the selection of urban highway alignment alternatives with application of the analytic hierarchy process: An environmentally sustainable approach

Abstract

This paper contains the proposition of a methodological process to be used during the planning phase of urban highways. It refers to a multicriteria analysis tool which selects the best route for a future highway considering not only geometrical engineering topics, most often used for highways definitions, but also important issues for modern society, such as environmental ones. This methodology was applied on the study of alignment alternatives of Sao Paulo's Ring Road, through interviews with some members of society and application of the Analytic Hierarchy Process.
