Problem Statement: Federal regulations require that major Intelligent Transportation Systems projects deployed with federal funding after April 2005 conform to the national ITS Architecture and that the architecture of planned and deployed projects be documented. The national ITS Architecture provides a framework to provide for consistency among ITS implementations within a region and across state borders. This includes such projects as dynamic message signs, traveler information systems, and traffic control. The South Dakota Rural ITS Deployment Plan, completed in 2000, recommends a program of ITS projects over the next eight years. A number of ITS projects are in progress, and others are planned in the near future. By April 2005, it will be necessary for the Department to be capable of reviewing ITS projects to determine their compliance with the National ITS Architecture.

Research is needed to define and develop South Dakota's ITS architecture. The research would consider how regional and specific projects fit into the state architecture. CVO/CVISN architecture development under a separate contract must also be considered. The technical panel and other ITS stakeholders may participate in an architecture process workshop in the beginning of the project to identify each stakeholder's systems, subsystems, interconnects and architecture flows. The researcher must then refine the architecture and further clarify how various elements fit within the national ITS architecture.



Findings: The South Dakota Statewide ITS Architecture is a statewide roadmap for transportation systems integration over the next approximately 15 years. The architecture has been developed through a cooperative effort by the state's transportation agencies, covering all modes and all roads in the state. The architecture represents a shared vision of how each agency's systems will work together in the future, sharing information and resources to provide a safer, more efficient, and more effective transportation system for travelers in the region. The ITS architecture is an important new tool that will be used by: Operating Agencies to recognize and plan for transportation integration opportunities in the region. Planning Agencies to better reflect integration opportunities and operational needs into the transportation planning process. Other organizations and individuals that use the transportation system in South Dakota. The ITS architecture provides an overarching framework that spans all of these organizations and individual transportation projects. Using the ITS architecture, each transportation project can be viewed as an element of the overall transportation system, providing visibility into the relationships between individual transportation projects and ways to cost-effectively build an integrated transportation system over time. The Statewide ITS Architecture provides a detailed view of the stakeholders, their roles and responsibilities, the ITS systems that exist or are planned, the transportation services that are or will be provided, the connections and information exchange requirements between the systems, the key functions of the systems, the standards applicable to planned deployments and the agreements needed for planned deployments. In addition the relationship of ITS projects to the overarching statewide ITS architecture was developed. The Statewide ITS Architecture is documented in an detailed report (of which this represents the executive summary) and in a hyperlinked website (at www.consystec.com ) that provides an easily accessible method of reviewing the details of elements and interfaces. The following paragraphs of this executive summary provide some key outputs of the effort. Stakeholder coordination and involvement was one of the key elements of the development of a statewide ITS architecture. Because ITS often transcends traditional transportation infrastructure, it was important to consider a range of stakeholders beyond the traditional traffic, transit, and maintenance areas. In addition, it was important to consider stakeholders in adjoining states.

Research Objectives:
1  To develop a regional architecture that includes South Dakota and the Metropolitan Planning Organizations that include Sioux Falls, Rapid City and Sioux City.

Research Tasks:
1  Perform a literature search regarding other state‚Äôs efforts, as well as those in Sioux Falls and Rapid City, to produce statewide ITS architectures.
2  Identify and document existing and near term ITS projects and efforts.
3  Identify and bring together stakeholders to inventory existing projects, identify needs, and begin the architecture development process.
4  Meet with the panel to summarize literature, findings and initial development of architecture based on stakeholder meetings.
5  Using the National ITS Architecture, develop a statewide architecture, including architecture flows, market packages, and interconnect diagrams, and provide in Turbo Architecture format that allows future modification. Include written descriptions in
6  Outline an implementation plan that provides SDDOT staff a method to evaluate future ITS projects to assure they comply with the statewide architecture.
7  Meet with the panel to present findings and architecture materials.
8  Provide training on the statewide architecture to select SDDOT and MPO staff. This should include how future projects may be added to the existing architecture.
9  Submit a final report including methodology, findings, conclusions, recommendations, and architecture deliverables.
10  Make an executive presentation to the Research Review Board.
