Sustainable Transportation Measures Guide

Performance measures allow decision-makers to monitor trends and assess impacts of activities over time. While many transportation agencies regularly use performance measures as part of standard planning and project development, their use to promote sustainability has historically been limited. More recently however agencies have begun to measure the ability of their systems to help protect natural resources, improve public health, strengthen energy security, expand the economy, and provide mobility to disadvantaged people.

This document describes opportunities to incorporate environmental, economic, and social sustainability into the transportation decision-making process. Focusing primarily on regional and metropolitian transportation agencies, the information in this guide can also be useful for states and local governments.

Throughout the guide several best practices from across the country are presented, along with 12 specific performance measures for agencies to consider. Each measure presents possible metrics, summarizes the relevant analytical methods and data sources, illustrates the use of each measure by one or more transportation agencies and describes opportunities to incorporate these measures into the transportation decision-making process.
