Deploying an ITS Warning System for No-Passing Zones on Two-Lane Rural Roads
(Virginia Tech, 2001-06-28)
A new safety application, as part of ITS Advanced Rural Transportation System (ARTS), has been developed to be deployed on a two-lane rural road (Route 114), in Southwest Virginia. The route segment under study is subject ...
Truck Modeling Along Grade Sections
(Virginia Tech, 2001-05-11)
This research effort first characterizes the trucks traveling along US highways by analyzing data from Interstate 81. It is hypothesized that I-81 is typical of US highways and thus can provide some insight into typical ...
Evaluation of Service Reliability Impacts of Traffic Signal Priority Strategies for Bus Transit
(Virginia Tech, 2002-06-03)
Recent progress in technology has facilitated the design, testing, and deployment of traffic signal priority strategies for transit buses. However, a clear consensus has not emerged regarding the evaluation of these ...
The Impact of Local/Short Haul Operations on Driver Fatigue
(Virginia Tech, 2000-05-23)
Massie, Blower, and Campbell (1997) indicate that trucks that operate less than 50 miles from the vehicle's home base comprise 58% of the trucking industry. However, despite being the largest segment, research involving ...
Non-contact Methods for Detecting Hot-mix Asphalt Nonuniformity
(Virginia Tech, 2006-09-21)
Segregation, or non-uniformity, in Hot Mix Asphalt (HMA) induces accelerated pavement distress(es) that can reduce a pavement's service life up to 50%. Quality Assurance procedures should detect and quantify the presence ...
Evaluation of Traffic Responsive Control on the Reston Parkway Arterial Network
(Virginia Center for Transportation Innovation and Research, 2009-02-01)
Traffic responsive plan selection (TRPS) control is considered an effective operational mode in traffic signal systems. Its efficiency stems from the fact that it can capture variations in traffic patterns and switch timing ...
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 ...
Field Investigation of High Performance Pavements in Virginia
(Virginia Center for Transportation Innovation and Research, 2005-01-01)
This study evaluated 18 pavement sections located in high-traffic highways in Virginia to find a premium pavement design with a life span of 40 years or more using current and past field experience. The selected pavement ...
Modernizing bridge safety inspection with process improvement and digital assistance
(Virginia Center for Transportation Innovation and Research, 2004-01)
This research effort was developed to record and analyze the Virginia Department of Transportation (VDOT) bridge/structure inspection processes as an aid to modernizing and automating these inspection processes through the ...
Fatigue Life Characterization of Superpave Mixtures at the Virginia Smart Road
(Virginia Center for Transportation Innovation and Research, 2005-08)
Laboratory fatigue testing was performed on six Superpave HMA mixtures in use at the Virginia Smart Road. Evaluation of the applied strain and resulting fatigue life was performed to fit regressions to predict the fatigue ...
