Abstract: In 1993, the Federal Highway Administration embarked on a program to develop a national system architecture (NSA) for intelligent-vehicle-highway-systems (IVHS, later renamed intelligent-transportation-systems). The project was completed in early 1996, with the delivery of documents totalling more than 10,000 pages. This paper examines the effects of the national system architecture on transportation management and control. Special emphasis is placed on California because of the state|s active participation since the project|s inception. The paper includes a review of NSA within the context of: (1) Functional areas of responsibility, (2) Content of communication and information residence, and (3) Lines of authority and resolution of decisions. The paper also identifies implementation issues for California, and reports on interviews with traffic managers and traffic technology developers. The paper concludes that despite the state|s participation, NSA is unlikely to significantly affect transportation deployments in the state.

Keywords: national system architecture; intelligent transportation system; California.
