National ITS Architecture Theory of Operations

The document chapters are structured as follows: Introduction; Executive Summary; An overview of the National ITS Architecture definition, operational concepts, and consensus based choices made in its development, as they pertain to this document. Assumptions This chapter describes the deployments/implementations used in the Theory of Operations; Operational Overview Organized by user services, this chapter describes the operation of the National ITS Architecture from a combined user/institutional and system perspective. The system perspective includes the subsystem processing and architecture flow communications required to implement the user services. The user perspective identifies the user interactions with the ITS; Operational and Interoperability Issues This chapter identifies key operational and interoperability issues and outlines the options that were considered in the National ITS Architecture development and the strategies chosen for addressing them. Issues addressed include: infrastructure based route selection; robustness to spatially different deployments; interjurisdictional issues; predictive modeling of link travel-time and congestion; development of public-private partnership models; and deployment of low cost and ubiquitous wireless communication services.
