Pedestrian Roadway Crossing Behavior

Human Factors Assessment of Pedestrian Roadway Crossing Behavior

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.

2013 Status of the Nation’s  Highways, Bridges, and Transit

This edition of the C&P report is based primarily on data through the year 2010; consequently, the system conditions and performance measures presented should reflect effects of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), which authorized Federal highway and transit funding for Federal fiscal years 2005 through 2009 (and extended through fiscal year 2012), as well as some of the impact of the funding authorized under the American Recovery and Reinvestment Act of 2009 (Recovery Act). None of the impact of funding authorized under the Moving Ahead for Progress in the 21st Century Act (MAP-21) is reflected. In assessing recent trends, this report generally focuses on the 10- year period from 2000 to 2010. The prospective analyses generally cover the 20-year period ending in 2030; the investment levels associated with these scenarios are stated in constant 2010 dollars.

Why Drivers Do What They Do

Tuesday, January 8th, 2013

In recent years, national attention toward the issue of driver distraction has increased among the transportation community, the media, and the public. Texting and cell phone use while driving, for example, are major safety concerns due to their role as contributing factors in a growing number of vehicle crashes. But roadway and roadside infrastructure also can contribute to driver distraction. For example, does the placement of changeable message signs at certain locations cause motorists to look away from the road more than they would otherwise? Do certain sign messages cause driver confusion or misunderstanding?

Highways in the Coastal Environment: Second Edition

Thursday, November 8th, 2012

Water level fluctuations include astronomical tides, storm surges, and long-term sea level rise or fall. Water level is important in coastal processes and engineering in part because it controls the location of wave influence on shorelines and structures. Geologically, sea level controls the overall location and shape of the continental shoreline. The definitions of tidal datums and surveying datums can be important for the design of engineering works near the coast.

Interactive Map: Save Our Bridges

Tuesday, October 16th, 2012

By accessing the Save Our Bridges Map, users can enter a zip code to immediately see the dangerous bridges in their area.
