Sustainability has increased in popularity as a key indicator for planning transportation projects.With that movement, evaluating the sustainability of transportation projects has becomenecessary for state departments of transportation (DOTs). Transportation Sustainability RatingSystems (TSRS) have been adopted for this purpose; however, different TSRSs employ differentmethods for determining or quantifying sustainability, and emphasize different sustainabilityfactors. Given the number, variability, and specificity of TSRSs available, an evaluation andpairing exercise of available systems is needed to help the state DOTs select a system bydetermining to what extent a given system suits the state DOT’s preferences This paper presentsa four step framework which identifies the most important capabilities in a TSRS as preferred bya state DOT and then facilitates weighting of those capabilities via a well-establishedmethodology, the Analytical Hierarchy Process. The paper also presents the implementation ofthis framework for Colorado DOT (CDOT) and Wyoming DOT (WYDOT). The frameworkresulted in the identification of INVEST to be the most suitable TSRS for CDOT and WYDOT.The framework developed for assessing TSRSs was proven to be a viable means for determiningrank and suitability of TSRS for DOTs.
