A variety of electric and alternative fuel vehicles are increasingly available to consumers, which should be good news for efforts to reduce greenhouse gas emissions. However, adoption of these new, cleaner technologies is hampered by inadequate infrastructure needed to support fueling of these vehicles. Recognizing this challenge, the FAST Act directs the Secretary of Transportation to designate alternative fueling corridors for EV and alternative fuel vehicles.

Study: One-way car-sharing reduces VMT, GHG emissions, and vehicle ownership
A recent study done by researchers at University of California-Berkeley has answered several questions many have had since car-sharing began by showing that car2go members in five North American cities reduced both their annual vehicle miles traveled and also their greenhouse gas emissions. Members also sold or delayed purchasing vehicles, resulting in each car-sharing vehicle removing seven to 11 private vehicles from the road.
New research reinforces the importance of the built environment to cycling mode share
A recently published study from Montreal sheds new light on the importance of the built environment in influencing bicycle commuting and the resulting impacts on greenhouse gas emissions. The researchers also estimated the effect of bicycle infrastructure accessibility on cycling mode share. They estimated the effect of the new bicycle infrastructure as yielding a 1.7 percent reduction in transportation GHG emissions, roughly equivalent to the estimated effects of replacing the city’s buses with hybrid models and electrifying the city’s commuter trains.
Northeast looks at GHG reductions that boost the economy
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.

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 densities—and thereby reducing travel distances—this relationship has been hard to quantify; conventional demand models simply take land use as an input. Filling this gap is a report and tool from TRB’s Transit Cooperative Research Program.

WSDOT accountability report replaces congestion with corridor capacity
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 report has a new name and a new emphasis. Instead of highlighting congestion, the 2013 Corridor Capacity Report focuses on capacity across all modes. Rather than measuring just motor vehicle throughput, it turns its attention to moving people, regardless of mode.
Oregon DOT promotes Drive Less Challenge
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 miles. The broader goal for the campaign is to raise awareness for ongoing alternative transportation programs aimed at reducing traffic congestion, environmental impacts, and other transportation system costs.
