This guidebook provides state departments of transportation (DOTs) and other transportation agencies with a practical and easy-to-use approach to identify and apply sustainability-related performance measures, some number of which may already be integrated into agency business practices, to produce a new lens through which decision makers can view their agency’s performance. It describes the underlying principles of sustainability as it relates to transportation, possible goals that can be used to address those principles, and performance measures that can be used to address those goals. Aspects of sustainability-related performance measures, including data sources and examples of use, are discussed. A reference compendium of performance measures has also been provided.
