Architecture UseThe National ITS Architecture is used to develop regional ITS architectures that define a framework for integration for a specific state, metropolitan area, or other region of interest. The National ITS Architecture includes a broad menu of options that can be selectively tailored and applied to a region. The National ITS Architecture makes it easier to develop regional ITS architectures that include all of the necessary elements in a consistent way. Basing each regional architecture on the National ITS Architecture also aids the private sector because consultants can develop expertise in the National ITS Architecture that transports from region to region.
A regional ITS architecture can effectively bridge the gap between strategic planning for an integrated surface transportation system and the ITS projects that support that strategic vision. The principal value of a regional ITS architecture is that it provides a context for projects that include ITS so that each project can build a piece of a larger system. The regional ITS architecture is a tool that can be used to visualize and articulate the overall ITS system for the region so that all the stakeholders in a region spend their money compatibly instead of competitively. A regional ITS architecture is useful during transportation planning and the initial phases of development of an ITS project.
Transportation Planning. A regional ITS architecture can be used as a tool to support metropolitan and statewide transportation planning. A regional architecture provides a means by which peer agencies can jointly define their vision for ITS development based on regional goals and objectives. Using the regional ITS architecture, a region can plan for technology application and integration to support more effective planning for operations.
Project Development. By using the regional ITS architecture, the steps taken by each project will be on the path to fulfilling the larger objectives set forth in the long range transportation plan. A well-maintained regional architecture that is created and maintained using Turbo Architecture can provide a tool for making a strong initial start at the systems engineering for a project.
