VDOT's District 2: Salem District ITS Architecture

Welcome to Virginia DOT's District 2: Salem District Regional Intelligent Transportation System (ITS) Architecture web site. This site provides information on all aspects of transportation-related information exchanges for the Salem District. At the district level, it is important that each interface with other districts and the statewide elements are standardized. The architecture is consistent in how it shows the detailed exchange of information between the Salem District systems (e.g., Local Signal Centers) and other district systems. This architecture also defines the details for the Salem District ITS including the district-to-statewide element interactions.
