Title: An improved methodology for multi-criteria assessment of highway sustainability
Author: Ramani, Tara Lakshmi
Abstract: The concept of sustainability has been widely discussed in relation to human activity and scientific development in recent times . There is an increased awareness of the current and future ramifications of people ?s everyday activities on the environment , and sustainable development aims to mitigate these impacts , as well as promote social equity and economic efficiency . A majority of research concerned with transportation sustainability addresses it at the policy -planning level , though there have been recent attempts at quantitatively evaluating it . These evaluations are mostly based on multicriteria decision making processes using performance measures . However , the methods and the performance measures developed are often not geared toward being practically implemented within a transportation agency ?s regular planning activities . This research effort seeks to improve upon existing sustainability evaluation processes for highways by proposing a methodology that addresses sustainability within the regular transportation planning paradigm , rather than as a separate concern . A more scientific approach to the scaling of various performance measures , as well as the evaluation of current and future planning scenarios on a common basis provides for an improved multi -criteria evaluation method . A case study was conducted using the proposed methodology for a section of US Highway 281 in San Antonio , Texas . The evaluation model developed in this study provides the basis for further research into applying decision -making processes to improve transportation sustainability by addressing some of the inherent drawbacks of existing research on sustainability evaluation .
