Welcome to the Commonwealth of Virginia’s Intelligent Transportation System (ITS) Architecture web site for the Virginia Statewide ITS Architecture. This site will provide you with information on all aspects of transportation-related information exchanges at the Virginia statewide level. At the statewide level, it is important that each interface with each region is standardized. The architecture is consistent in how it shows the detailed exchange of information between the statewide systems (e.g., 511) and the regional systems. This architecture defines the details for the statewide ITS as well as the statewide-to-statewide element interactions.
