Virginia's Statewide and Regional ITS Architectures
Welcome to the Commonwealth of Virginia's Intelligent Transportation System (ITS) Architecture web site. This site will provide you with information on all aspects of transportation-related information exchanges at the statewide level as well as the five regional levels within Virginia.
The Architecture development was led by the VDOT Central Office with participation from each of the regional offices and central office initiative programs. The architectures were developed following the FHWA guidance on Regional ITS Architecture development. The development process involved numerous stakeholders who provided inputs in many stakeholder meetings across the Commonwealth.
The intent of these architectures is to guide ITS planning and project development so that ITS is implemented in the most efficient and economical manner. The architectures identify what functionality exists today and what is planned or desired in the future. In this way, the architecture provides a vision for ITS in Virginia. It is expected that as more stakeholders examine the architecture more ideas will be generated for ITS and, in some cases, more clarity regarding what is currently defined in the architecture will be brought forward making the architectures better and more accurate over time.
The architectures will be maintained with new or revised information through a maintenance program to provide the most accurate information for planning ITS. The Maintenance Plan included with all the architectures guides how that maintenance will occur. The use of the architectures is vitally important to ITS deployment. Architecture use in the planning process maximizes the integration opportunities to be considered and the most logical project sequencing that supports the overall vision for ITS. The application of the architecture in planning and project development is discussed in the Implementation Plans included for each architecture. These plans also deal with how the architecture components can be used in developing projects following the systems engineering process. These plans can be found under the Resources link on each architecture webpage banner.
The transportation environment in Virginia is changing constantly. New demands, new challenges, different organizational structures, and economic realities all affect the transportation system and the services it offers. It is important for stakeholders to stay engaged in the ITS discussion and ITS architecture is a valuable forum for that conversation. It provides a basis for starting the discussion and a platform for modifying the vision to reflect what is needed.
The architecture website is divided into 10 architecture areas organized by VDOT District:
