ITS Architecture Reference

The Intelligent Transportation Systems ITS Architecture Program provides the systems architecture reference and software tools to allow for tailored yet interoperable ITS installations nationwide covering 150 plus services analogous to apps; allowing for interoperable cross jurisdictional ITS and connectivity services for vehicles. The current version see: www.arcit.org starts to incorporate automated vehicle and automation specific service packages as well as updates to better reflect multimodal and accessible transportation MAT. It also incorporates connectivity and multiple views covering organizational, physical and functional objects and their interrelationships to meet the needs of multiple users. It includes detailed identification of suitable standards as well as standards gaps requiring further action for connectivity services identified via an extensive internationally cooperative effort. Tasks will include expansion of the architecture reference and tools to add new services requested by users and identified via analysis of technological evolution, along with updates to improve security and increase the degree of detail for key services. The task also includes direct support to State/local implementers as well as updating of reference materials, coordination with and technical support for USDOT deployment initiatives, and specific standards related support to address high priority needs not covered elsewhere in the ITS Architecture and Standards AS program. When viable, international cooperation opportunities, primarily on automation and security, will continue to be leveraged to maximize the benefit to the US program.
