WHY AN ITS ARCHITECTURE?
On January 8, 2001, the US DOT published two important and related documents in the Federal Register: the FHWA Final Rule on the National ITS Archtecture and the FTA Policy on the National ITS Architecture. The Rule/Policy implements Section 5206(e) of TEA-21, which requires that all ITS projects funded from the Highway Trust Fund be in conformance with the National ITS Architecture and National ITS Standards.
The National ITS Architecture, adopted in 1996, provides a technical and institutional framework to guide the coordinated deployment of ITS by public agencies and private organizations alike. It defines the functions performed by ITS components and the various ways in which components can be interconnected. Although the architecture is national in scope, it can be localized for regions, corridors, and transportation authorities. It can benefit state and local transportation agencies, like the Municipality of Anchorage, by helping them to save time and money in achieving maximum benefits through the implementation of integrated ITS.
The FHWA/FTA Final Rule/Policy for applying the National ITS Architecture at the local level requires that Anchorage have an approved regional ITS architecture that is consistent with both the national and state ITS architectures. In this context, an architecture is a framework, a systems analysis tool, which describes existing and planned transportation system-wide functions (activities, services, and information exchange flows), as well as system users (including vehicle drivers, pedstrians, multimodal passengers, fleet operators for passenger and freight, and operators of transportation systems and networks). It allows planners to identify specific areas where ITS services and technologies can be used to address the needs, issues and objectives of travel mobility, safety and efficiency. Finally, the architecture describes a systematic plan to show how all the technologies and services will be brought together - deployed - to function in harmony with each other.
MOA REGIONAL ITS ARCHITECTURE & CURRENT PROJECTS
During the past three years, the Municipality of Anchorage has been developing a regional Anchorage ITS architecture with the help of ADOT&PF's ITS consultant. ITS projects needed in the future were identified through an extensive outreach process, and are included in the final Anchorage ITS Implementation Plan.
The final ITS Implementation Plan, approved by the AMATS Policy Committee, October 14, 2004, will be used as input to guide decisions for deploying ITS in the future for MOA, and will be addressed during development of the Long-Range Transportation Plan, and subsequent corridor plans. The MOA Regional ITS Architecture Final Report, Version 1.1, has been modified to reflect approved changes, and is posted to the following link: www.muni.org/transplan/ITSLibrary.cfm
In the meantime, Anchorage is already deploying ITS projects. The Final Rule/Policy defines ITS as electronics, communications, or information processing used singlely or in a combination to improve the efficiency or safety of a surface transportation system. An "ITS project" is defined as any project that in whole or in part funds the acquisition of technologies or systems of technologies that provide or significantly contribute to the provision of one or more ITS user services as defined in the National ITS Architecture.
Examples of ITS projects, or projects which may have ITS elements (electronics, communications, or information processing), in the 2004-2006 Anchorage Metropolitan Area Transportation Study (AMATS) Transportation Improvement Program (TIP), approved January 2005, includes but are not limited to, the following:
