511 Virginia

511 Virginia is a statewide web and phone service that disseminates traffic and weather information on over 400 roads throughout the Commonwealth of Virginia. The service, sponsored by the Virginia Department of Transportation (VDOT), has been in operation statewide since February 2005.

The Virginia Tech Transportation Institute (VTTI) has been involved with the development and operation of the service since its inception and currently serves as quality controller for the 511 system, including verifying that the information is indeed disseminated to the public through e–mail alerts, the phone and the web, and notifying the appropriate parties of any failures.
