Research Highlights

Application of WIM Data for Improved Modeling, Design, and Rating

Christopher Monsere
Christopher Higgins , Andrew Nichols
The objectives of this research are to: 1.) collect, sort, filter, and archive WIM data to permit development of long-term continuous records of high-quality WIM data and; 2.) use the WIM data archive to monitor WIM sensor health, develop loads for asphalt design, load models for bridge rating and deck design, and monitor freight movement on the highway system, specifically the volume, weight, safety, and time demands. Researchers will collect WIM data from DOT agencies (ODOT and others natio... Read More

Creating Livable Communities through Connecting Vehicles to Pedestrians and Cyclists

John MacArthur
Safety of pedestrians and bicyclists is a significant problem in U.S., with 4,743 fatalities and 76,000 injuries of pedestrians and 726 fatalities and 49,000 injuries of bicyclists in 2012 (NHSTA 2014a & b). Establishing and creating livable communities relies on making walking and bicycling as safe and convenient as possible. The U.S. DOT has embarked upon a major research program toward implementing connected vehicle safety technologies, applications and systems using short-range communicat... Read More
