Architecture Scope


Last Updated January 2014

The Wisconsin Statewide ITS Architecture represents the existing and planned Intelligent Transportation Systems (ITS) deployed and their operations for the state of Wisconsin. Broad stakeholder involvement and cooperation allowed for the development of the architecture over many years. Many of the existing stakeholders are represented based on their involvement in the process along with how much information that is available on their systems and operations.

The ITS Architecture describes existing and planned elements, interfaces, and operational requirements of ITS in Wisconsin. Connections between major ITS systems, such as WisTransPortal, Wisconsin 511, and the Statewide Traffic Operations Center (STOC) Advanced Traffic Management System, are represented. This Statewide ITS Architecture can be used to inform how systems interact and function together to create a transportation system that is safer and more efficient. This Statewide Architecture was consolidated and updated from previous WisDOT District and Regional architectures in 2010, and it continues to actively evolve.

Geographic Scope

The Wisconsin Statewide ITS Architecture is the primary regional architecture for the State of Wisconsin. It includes all five WisDOT regions in the state of Wisconsin, many agencies, and interactions with the bordering states, agencies, and coalitions. The regional architecture supports information flows to all levels of state and local government, universities, contractors, media, and other organizations throughout Wisconsin and in neighboring states.

WisTransPortal ITS Architecture

From November 2012, the WisTransPortal ITS Architecture has been fully incorporated into the Wisconsin Statewide ITS Architecture. The WisTransPortal project provides centralized access to Wisconsin statewide traffic operations and safety data. It is physically located at the University of Wisconsin-Madison, and is directly connected to the WisDOT ITSNet which provides a dedicated network path to the STOC and other WisDOT locations. The WisTransPortal project has been developed through primary sponsorship of the WisDOT Bureau of Traffic Operations (BTO). The overall WisTransPortal system and key functional areas are represented as Projects and are found in the Projects tab above.
