The test beds are being operated by the Connected Vehicle/Infrastructure University Transportation Center, a Tier 1 University Transportation Center operated by a consortium made up of the Virginia Tech Transportation Institute, the University of Virginia's Center for Transportation Studies, and Morgan State University.
Robust vehicle-to-vehicle, vehicle-to-infrastructure, and vehicle-to-device communication will enable applications addressing the U.S. Department of Transportation’s strategic goals of safety, state of good repair, economic competiveness, livable communities, and environmental sustainability.
In Northern Virginia, as you speed along Interstate 66 in Fairfax County, or move more sedately along Routes 29 and 50, you may notice large metal boxes with eggbeater-like antennae along the sides of the roads.
"The Northern Virginia test bed is a tremendous asset with respect to testing and deployment of research findings," said Center Director Tom Dingus, director of the Virginia Tech Transportation Institute. "Key elements of this test bed are strong partnerships with local agencies, including law enforcement and transit providers, particularly the Fairfax County Transit Authority."
"The Fairfax County test bed experiences the very real and significant transportation challenges in terms of congestion, safety, and environmental impact that are of concern nationwide,” said University of Virginia Consortium Leader Brian Smith, a professor and the chair of the department of civil and environmental engineering. "Through this test bed, our research team will have the opportunity to develop, test, and demonstrate tangible connected vehicles applications that will have a positive impact on the travelers’ experience."
Southwest Virginia test bed resources include Route 460 in Montgomery County for real-world testing as in Northern Virginia, and Virginia's Smart Road, a closed-circuit transportation research facility in Blacksburg where experimental procedures can be tested.
"The test beds provide a variety of roadway types, topography, and driver types that allow us to exercise connected-vehicle systems across a range of environments under controlled conditions, so that a high number of equipped vehicle interactions will occur," said Morgan State Consortium Leader Andrew Farkas, a professor and the director of the National Transportation Center.
The 55 roadside units report road hazards, optimize de-icing operations, warn of congestion and emergency vehicles, and monitor pavement condition. The instrumented vehicles, which include 10 cars, a semi-truck, and a bus, have forward-collision, road-departure, blind-spot, lane-change, and curve-speed warning system and advance geographic information systems. They also have sophisticated recording devices that download to the University Transportation Center so that researchers can observe in real-time and accumulate data for later transportation.
Test bed development and vehicle instrumentation will be finalized by the end of the year.
Research under way includes safety and human factors of adaptable stop/yield signs; connected vehicle applications for adaptive lighting; intersection management using in-vehicle speed advisory/adaptation; eco-speed control; "intelligent" awareness system for roadway workers; emergency vehicle-to-vehicle communication; connected vehicle enabled freeway merge management; infrastructure safety assessment; infrastructure pavement assessment; and connected vehicle-infrastructure application development for addressing safety and congestion issues related to public transportation, pedestrians, and bicyclists. Future research projects include optimized routing, road hazard reporting, optimized de-icing, beacon for at-risk pedestrians, and vehicle-to-vehicle communication to enhance rear signaling.
The consortium universities will conduct education and outreach programs to safely and efficiently implement successful connected vehicle and infrastructure technologies.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
