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 ...
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.
Modeling 100-car safety events: a case-based approach for analyzing naturalistic driving data: final report
(Virginia Tech. Virginia Tech Transportation Institute, 2009-09-30)
This study developed an integrated framework for modeling the safety outcomes of naturalistic driving studies and addressed several critical methodological issues. The results indicate a certain level of discrepancy between ...
Using high-speed texture measurements to improve the uniformity of hot-mix asphalt
(Virginia Center for Transportation Innovation and Research, 2003-05-01)
This study introduces Virginia's efforts to apply high-speed texture measurement as a tool to improve the uniformity of hot-mix asphalt (HMA) pavements. Three approaches for detecting and quantifying HMA segregation through ...
Enhanced Night Visibility Series, Volume XIII Phase III - Study 1: Evaluation of Discomfort Glare During Nighttime Driving in Clear Weather
(United States. Federal Highway Administration, 2005)
Phase III-- Study 1 was performed to further explore findings on far infrared (FIR) systems from Phase II, to investigate near infrared (NIR) and high intensity discharge (HID) technologies, and to investigate detection ...
Live Stop-Controlled Intersection Data Collection
(Virginia Center for Transportation Innovation and Research, 2007-12)
This report describes an experimental investigation performed at live intersections to gather infrastructure-based naturalistic driver approach behavior data. This data was collected and analyzed with the goal of understanding ...
Composite Pavement Systems: Synthesis of Design and Construction Practices
(Virginia Center for Transportation Innovation and Research, 2008-11-01)
Composite pavement systems have shown the potential for becoming a cost-effective pavement alternative for highways with high and heavy traffic volumes, especially in Europe. This study investigated the design and performance ...
Enhanced Night Visibility Series, Volume I: Executive Summary
(United States. Federal Highway Administration, 2005-12)
This volume, an executive summary of the Enhanced Night Visibility project, is the first of 18 volumes that report on the project's evaluation of the merit of implementing supplemental ultraviolet headlamps, supplemental ...
Contributing Factors to Run-off-road Crashes and Near-crashes
(United States. National Highway Traffic Safety Administration, 2009-01)
The purpose of this investigation is to identify factors associated with run-off-road (ROR) crashes. Events from the 100-Car Naturalistic Driving Study that constituted ROR crash or near-crash events were investigated to ...
Assessment of a Drowsy Driver Warning System for Heavy Vehicle Drivers: Final Report
(United States. National Highway Traffic Safety Administration, 2008)
Drowsiness has a globally negative impact on performance, slowing reaction time, decreasing situational awareness, and impairing judgment. A field operational test of an early prototype Drowsy Driver Warning System was ...
