Friday, April 22nd, 2011
TRANSPORTATION RESEARCH BOARD
North America’s rural landscape is dotted with isolated settlements, villages, and small towns that are typically located on rural roads where the general speed limit is 55 to 60 mph (90 to 100 km/h). Motorists are expected to slow down as they pass through these settlement areas, reducing their operating speed to 30 or 40 mph (50 or 65 km/h) in sections of road known as transition zones…There is clearly a need for better and more information concerning rural high-to-low speed transitions. This synthesis report is a preliminary step in that direction.

Wednesday, April 13th, 2011Potential Impact of Gasoline Price Increases on U.S. Public Transportation Ridership, 2011 -2012
Thursday, March 31st, 2011
AMERICAN PUBLIC TRANSPORTATION ASSOCIATION
Experience over the past decade, backed by several notable research studies, shows that price increases in gasoline cause related increases in public transportation ridership. Based on that information, this report provides a model that projects future increases in public transit ridership that will accompany rising gasoline prices.
Alternative Approaches to Funding Highways
Tuesday, March 29th, 2011
CONGRESSIONAL BUDGET OFFICE
By themselves, fuel taxes cannot provide a strong incentive for people to avoid overusing highways-that is, to forgo trips for which the costs to themselves and others exceed the benefits. This study examines broad alternatives for federal funding of highways, focusing on fuel taxes and on taxes that could be assessed on the basis of the number of miles that vehicles travel.

Dear Friends,
It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.
Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.
We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.
We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
