FHWA\u2019s Final Rule and FTA\u2019s Policy for Applying the National ITS Architecture at the Regional Level

Abstract

The intention of the FHWA/FTA Rule and Policy is to foster integration of the deployment of regional ITS systems. Regional ITS architectures help guide the integration of ITS components. During the development of a regional ITS architecture, agencies that own and operate transportation systems must together consider current and future needs to ensure that today's processes and projects are compatible with future ITS projects. ITS components that operate together and as part of a system will enhance safety and mobility and reduce the possibility of costly incompatible systems in the future. This document addresses the following subjects: A. The reason for the Rule/Policy; B. The relationship of the National ITS Architecture to regional ITS architectures; C. New requirements and the use of systems engineering; D. The relationship of the regional ITS architecture to ITS standards; E. Tools for the ITS practitioner: training and technical assistanc
