Determination of the In-Place Hot-Mix Asphalt Layer Modulus for Rehabilitation Projects Using a Mechanistic-Empirical Procedure
(Virginia Center for Transportation Innovation and Research, 2006-07-01)
This project evaluated the procedures proposed by the Mechanistic-Empirical Pavement Design Guide (MEPDG) to characterize existing hot-mix asphalt (HMA) layers for rehabilitation purposes. Thirty-three cores were extracted ...
Transit Signal Priority Project Phase II Field and Simulation Evaluation Results
(Virginia Center for Transportation Innovation and Research, 2006-03-01)
Transit Signal Priority (TSP) is recognized as an emerging technology that is capable of enhancing traditional transit services. Basic green-extension TSP was implemented on U.S. Route 1 in the Northern Virginia Area (or ...
Intersection Decision Support: Evaluation of a Violation Warning System to Mitigate Straight Crossing Path Collisions
(Virginia Center for Transportation Innovation and Research, 2006-04)
This project entailed the design, development, testing, and evaluation of intersection decision support (IDS) systems to address straight crossing path (SCP) intersection crashes. This type of intersection crash is responsible ...
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 ...
