Stemming from projects intended to address the severe traffic congestion in the Puget Sound region, WSDOT's ITS program has grown to include many regional projects outside of the Puget Sound region and several statewide deployments. Traffic surveillance and control, winter maintenance, and traveler information are some of the areas where WSDOT's ITS efforts have had a positive impact in addressing Washington's transportation issues. The development of a statewide ITS Architecture will provide a framework to link the separate projects and provide a path to integrate ITS applications across the state. The previous work undertaken in developing regional ITS Architectures for Washington encouraged a bottom-up approach to developing this statewide Architecture. An important project task was reviewing and compiling past work, and applying a WSDOT perspective to each regional architecture. Additional project tasks included stakeholder identification and operational conceptual development to lay the groundwork for interagency communication and coordination. Taken together with several statewide ITS initiatives, the statewide ITS Architecture was developed from these current and past efforts. Tables, graphs, appendices, 89p
