Pavement Marking Visibility Requirements During Wet Night Conditions
(Virginia Center for Transportation Innovation and Research, 2006-11)
This study investigated the performance of pavement markings in wet night conditions. Typically, performance will decrease in wet conditions. The degradation is a result of flooding of the marking optics and a change in ...
Environmental Impact of Freight Signal Priority with Connected Trucks
Traffic signal priority is an operational technique employed for the smooth progression of a specific type of vehicle at signalized intersections. Transit signal priority is the most common type of traffic signal priority, ...
Development and validation of a luminance camera: final report
(Virginia Tech. Virginia Tech Transportation Institute, 2009-02-11)
Under the sponsorship of the National Surface Transportation Safety Center for Excellence (NSTSCE), an effort was undertaken to develop a system of image capture to analyze luminance data gathered in naturalistic driving research.
Economic Evaluation of Pavement Management Decisions
The Washington State DOT (WSDOT) was an early pioneer in the implementation of pavement management, starting with pavement condition data collection in 1969, and the establishment of a computerized pavement management ...
