Wet Night Visibility of Pavement Markings
(Virginia Center for Transportation Innovation and Research, 2004-10)
This report describes an investigation into the performance of pavement markings in wet night conditions. The performance of a typical pavement marking will degrade when it gets wet. This is a result of the flooding of the ...
A Method to Enhance the Performance of Synthetic Origin-Destination (O-D) Trip Table Estimation Models
(Virginia Center for Transportation Innovation and Research, 1998-01)
The conventional methods of determining origin-destination (O-D) trip tables involve elaborate surveys, e.g., home interviews, that require considerable time, staff, and funds. To overcome this drawback, a number of ...
Reducing fog-related crashes on the Afton and Fancy Gap Mountain sections of I-64 and I-77 in Virginia
(Virginia Center for Transportation Innovation and Research, 2002-10)
The Fancy Gap and Afton Mountain interstates have a long history of fog-related, multivehicle crashes. Because of its earlier involvement in the installation and evaluation of the original Afton Mountain in-pavement fog ...
Assessment of the Performance of Light-Emitting Diode Roadway Lighting Technology
(Virginia Transportation Research Council, 2015-10)
This study, championed by the Virginia Department of Transportation (VDOT) Traffic Engineering Division, involved a thorough investigation of light-emitting diode (LED) roadway lighting technology by testing six types of ...
Naturalistic Driving Study: Technical Coordination and Quality Control (SHRP 2 Report S2-S06-RW-1)
(Transportation Research Board, 2015)
Identification of Consented Driver Trips in the SHRP 2 Naturalistic Driving Study Data Set
(Virginia Tech Transportation Institute, 2015-02)
The Second Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study (NDS) data set contains approximately 5.51 million naturalistic driving trip files across thousands of consented drivers, making it the ...
Best Practices and Performance Assessment for Preventative Maintenance Treatments for Virginia Pavements
(Virginia Transportation Research Council, 2015-08)
Preventive maintenance has the potential to improve network condition by retarding future pavement deterioration. This report outlines guidelines for implementing a preventive maintenance policy for bituminous pavements. ...
Automated Vehicle Crash Rate Comparison Using Naturalistic Data
(Virginia Tech Transportation Institute, 2016-01-08)
This study assessed driving risk for the United States nationally and for the Google Self-Driving Car project. Driving safety on public roads was examined in three ways. The total crash rates for the Self-Driving Car and ...
Safety, Operational, and Energy Impacts of In-vehicle Adaptive Stop Displays Using Connected Vehicle Technology
(Connected Vehicle/Infrastructure University Transportation Center (CVI-UTC); Research and Innovative Technology Administration, 2015-07-30)
Un-signalized intersections create multiple opportunities for missed or misunderstood information. Stop sign-controlled intersections have also been shown to be a source of delay and emissions due to their frequent, often ...
Infrastructure Pavement Assessment & Management Applications Enabled by the Connected Vehicles Environment – Proof-of-Concept
(Research and Innovative Technology Administration; Connected Vehicle/Infrastructure University Transportation Center (CVI-UTC), 2015-09-30)
The objective of this project was to develop prototypes and conduct a field test of system level applications of a connected vehicle pavement condition measurement system. This allowed the research team to: (1) investigate ...
