Virginia ITS Architectures

The original VDOT District-based ITS Architectures have been updated to support the current regional operations approach. VDOT operations are now organized around 5 operating regions. Architectures have been developed for each region by harmonizing the district based architectures that were already in existence. The Northern Virginia ITS Architecture is one of the 5 regional architectures. The other regional architectures are defined for the Eastern, Central, Southwestern, and Northwestern regions. In addition, VDOT has defined a Statewide ITS Architecture for the first time. The Virginia Statewide ITS Architecture includes statewide systems and their interfaces with other statewide and regional systems. All of these architectures can be found at http://local.iteris.com/virginiaitsarchitecture/.
