The use of Deflection Measurements in Pavement Management of the Primary Road Network of Wallonia, Belgium
The road authorities of the primary road network of motorways and main roads in Wallonia (Belgium) determined the priorities for road maintenance from surface characteristics such as roughness, skid resistance and rutting. ...
Towards developing a US-EU common distracted driving taxonomy : updating a naturalistic driving data coding approach
(Virginia Tech. Virginia Tech Transportation Institute, 2011-12-07)
Naturalistic video data reduction is a process of identifying information from video and putting it into a format that can be analyzed. Developing a sufficiently detailed event coding scheme is critical to this process. ...
Latest Development in the Processing of Pavement Macrotexture Measurements of High Speed Laser Devices
Pavement macrotexture is an important property that affects tire-pavement interactions like friction, tire pavement noise, splash and spray, and rolling resistance. Macrotexture measurement is generally divided into two ...

Common Data Elements between the Large Truck Crash Causation Study Investigations and Commercially Available Onboard Monitoring Systems
At the heart of traffic safety is the identification of factors that lead to crashes. With this knowledge, interventions can be developed to mitigate or prevent these factors from occurring in the future. Post hoc ...
Development of a Framework for Evaluating Yellow Timing at Signalized Intersections
(Virginia Center for Transportation Innovation and Research, 2011-02-01)
Studies show that the proper design of clearance intervals has significant implications for intersection safety. For example, in 2001, approximately 218,000 red-light-running crashes occurred at signalized intersections ...
