Research shows that increased physical activity associated with active transport could generate a large net improvement in population health. Measures would be needed to minimize pedestrian and bicyclist injuries. Together, active transport and low-carbon driving could achieve greenhouse gas

This report presents the findings of research completed for the second Strategic Highway Research Program (SHRP 2) Capacity Project C09, Incorporating Greenhouse Gas Emissions into the Collaborative Decision-Making Process. It provides a framework and methods for assessing greenhouse gas

This report explores environmental health and Safe Routes to School through a review of the relationship between environmental health and school travel, a discussion on measuring the environmental health impacts of school travel, and five examples of methods used by SRTS programs to estimate the

This report is a summary of key findings covers a variety of studies on climate change and its ramifications for the transportation sector. It provides a concise summary of transportation’s contributions to climate change and mitigation policy levers. It also discusses various state DOTs’

This report analyzed the energy efficiency of 12 of the world’s largest economies in four areas including the transportation sector. They used 27 metrics roughly divided between evaluation of quantifiable results and policies. Download the full report.

This report is intended to provide transportation agencies with information that will better enable them to consider the implications and evaluate the feasibility of implementing renewable energy and fuel options in the ROW. The findings presented in this report are based on a review of the

Rails to Trails Conservancy issued a short synopsis of the results of the four-year Nonmotorized Transportation Pilot Program conducted in four communities across the U.S.  It includes useful statistics such as change in bicycle and walking mode, number of miles of trails built, and number of

Ecodriving is a collection of changes to driving behavior and vehicle maintenance designed to impact fuel consumption and greenhouse gas (GHG) emissions in existing vehicles. Because of its promise to improve fuel economy within the existing fleet, ecodriving has gained increased attention in

The mission of Colorado’s Energy Smart Transportation Initiative was to develop a framework for considering energy efficiency and greenhouse gas (GHG) emissions in transportation decision-making. With SSTI assistance, a collaborative team composed of federal and state agencies, MPOs, and rural

Transportation strategies that reduce emissions and conserve energy and grouped into either “cleaner vehicles” or “mobility management” (VMT reduction and demand management.) This report examines the cost effectiveness of these two strategies. Download full report.
