National Trail Surface Study

Figure M Statistical significance of stability between surface compositions 

NATIONAL CENTER ON ACCESSIBILITY
The impetus for the National Trails Surface study was to investigate alternatives to the typical firm and stable surface materials of asphalt, concrete, or boardwalk. It is a common misconception that in order to make a trail surface firm and stable, it needs to be paved. Professionals have found that using soil stabilizers, or natural aggregates, can be effective alternatives to creating a trail surface that meets accessibility guidelines (Boone, 2008).

Human Factors Assessment of Pedestrian Roadway Crossing Behavior

FEDERAL HIGHWAY ADMINISTRATION
Pedestrian–vehicle crashes are both common and deadly. In 2010, 13 percent of all fatal crashes involved pedestrians. Of these, 68.1 percent occurred outside intersections. As a result of thelarge proportion of pedestrian fatalities that occur at non-intersection locations, it is important toinvestigate the causal factors of these collisions. Despite the large proportion of crashes, little research has investigated the reasons pedestrians cross roadways at unmarked locations.

Perceptions of Water Use

Monday, March 10th, 2014
Attari 1

Most Americans assume that water supply is both reliable and plentiful. However, research has shown that with climate change, water supply will become more variable due to salinization of ground water and increased variability in precipitation. Some have argued that rather than focusing on increasing freshwater supply alone, we need also to reduce water demand. Demand-side policy responses to future freshwater variability will benefit from a deeper understanding of public perceptions of water use, which is the focus of this study.

As Congress Struggles for Ways to Fund the Next Transportation Reauthorization, States Are Taking Matters Into Their Own Hands

Thursday, March 6th, 2014

Innovation Newsbriefs
Vol. 25, No. 4 rev
For the transportation community, anxious about the uncertain future of the surface transportation program, recent events offered little reassurance. The President’s proposal for a four-year $302 billion transportation reauthorization, part of the administration’s FY 2015 Budget, met with a skeptical reception on Capitol Hill. “This budget isn’t a serious document; it’s a campaign brochure,” House Budget Committee Chairman Paul Ryan (R-WI) said dismissively. “Perhaps the most irresponsible budget yet,” commented House Speaker John Boehner (R-OH). The lawmakers’ negative reaction was no doubt amplified by the fact that the President’s budget ignored the spending levels painfully negotiated by Sen. Patty Murray (D-WA) and Rep.Ryan just last December. The Administration’s proposal exceeds the bipartisan budget agreement by $56 billion.
