Virginia Smart Road
The Virginia Smart Road is a unique, state-of-the-art, full-scale, closed test-bed research facility managed by VTTI and owned and maintained by the Virginia Department of Transportation (VDOT). The Smart Road continues to play an important role in the overall success of the institute and its research endeavors. Transportation scientists and product developers have spent more than 20,000 hours conducting research on this high-tech highway since its opening.
The Virginia Smart Road is now an FAA approved testing facility for flight.
Smart Road Features

- Wide shoulders for safe maneuvering during experimental testing
VTTI houses the Smart Road Control Room through which on-road research is scheduled and overseen.
Dispatchers monitor the Smart Road from a computer-equipped control center that is staffed 24/7. Researchers can directly and indirectly observe highway traffic and driver performance using surveillance cameras available in the control room. Engineers can also control the lighting and the weather on the Smart Road.
VTTI serves as the primary quality assurance/quality control (QA/QC) agency for the VDOT 511 Virginia project. The 511 system is designed for travelers and delivers information about events that may affect traffic, such as crashes, congestion, road work, and inclement weather.
QA/QC services provided by VTTI include but are not limited to:
- Reviewing entries within the VDOT VaTraffic incident management system.
- Monitoring the various 511 public services to ensure that VaTraffic information is delivered to the public in an accurate and timely manner. These 511 public services include:
- The 511 public website that provides coverage for most roads in Virginia;
- The 511 interactive voice response phone system (dial 511), which includes information for approximately 400 Virginia roads (all interstate roads and most primary roads);
- The 511 Virginia Alert emails, available free to the public via subscription; and
- Dynamic message boards located at nine welcome centers across Virginia.
The 511 and VaTraffic systems are monitored 24/7, 365 days per year from the Smart Road Control Room.
