Northeast looks at GHG reductions that boost the economy

By Eric Sundquist Clean transportation investments funded by market-based user charges would reduce greenhouse gas emissions while also providing a net economic benefit, a study for five Northeastern states and the District of Columbia contends. The study was released to coincide with

Quantifying Transit’s Impact on GHG Emissions and Energy Use—The Land Use Component (TRB, 2015)

Transit often fails to get the credit it deserves for reducing traffic and emissions. In most U.S. cities, transit’s mode share is in the single digits, so the direct effect of ridership seems small. And while it’s clear that even in places with low mode share transit plays a role in raising

New tool estimates transit’s effect on VMT and emissions

By Eric Sundquist Transit often fails to get the credit it deserves for reducing traffic and emissions. In most U.S. cities, transit’s mode share is in the single digits, so the direct effect of ridership seems small. And while it’s clear that even in places with low mode share transit plays

WSDOT accountability report replaces congestion with corridor capacity

By Robbie Webber Washington State Department of Transportation has been rightfully proud of their accountability and transparency with their quarterly Gray Notebook, which details system performance and project delivery. As part of that, they have issued an Annual Congestion Report. But the 2013

Oregon DOT promotes Drive Less Challenge

By Dan Moser On October 21, Oregon Department of Transportation and its regional transportation partners launched the first statewide Oregon Drive Less Challenge.  The immediate goal of the campaign is to reduce statewide vehicle miles traveled in single occupancy vehicles by half a million

New report outlines steps needed to reduce petroleum use and greenhouse gas emissions

By Bill Holloway A new report outlines what would be required to substantially reduce both petroleum usage and greenhouse gas emissions by 2050. It concludes that the goals are ambitious but achievable; however, government incentives, mandates, and research funding will be needed. The goals are

Health Cobenefits and Transportation-Related Reductions in Greenhouse Gas Emissions inthe San Francisco Bay Area (American Journal of Public Health, 2013)

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

Incorporating Greenhouse Gas Emissions into the Collaborative Decision-Making Process (TRB, 2013)

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

ACEEE finds U.S. ranks last in energy efficiency in transportation

By Mary Ebeling A new report from the American Council for an Energy Efficient Economy finds that, among 12 major world economies analyzed for the report, the U.S. ranks dead last in the energy efficiency of its transportation sector. Improving transportation’s energy efficiency hinges on

Ecodriving and Carbon Footprinting: Understanding How Public Education Can Reduce Greenhouse Gas Emissions and Fuel Use (Mineta Transportation Institute, 2012)

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
