Nationwide implementation of Intelligent Transportation System (ITS) services will result from a multitude of individual deployment decisions by public agencies and the private sector. The National ITS Architecture creates the opportunity for interoperability across these diverse ITS deployments while preserving flexibility and choice for the many implementers. The architecture is implemented to achieve these benefits in three principal ways: (1) adaptation or development of consensus standards for transportation products based on architecture requirements, (2) development of regional architectures which interpret the national architecture and tailor it to support integrated regional ITS solutions, and (3) incremental deployment of architecture compatible systems. The Implementation Strategy defines a series of steps that encourage efficient deployment of architecture compatible systems. These include: Identification of basic building blocks that apply to most ITS deployments, Focus on near-term problems and the early deployments best suited to addressing those problems through the Intelligent Transportation Infrastructure initiative, Further encourage private sector participation in ITS deployment, Parallel advancements in the number of ITS services offered and the degree of system integration over time. Each of these steps are used to inform state and regional guidance as well as specific US DOT recommendations. This summary will highlight the main findings that are more fully developed and supported in the body of the Implementation Strategy document. |
