Estimation of importance of intelligent transport systems (ITS) architecture

Abstract

This paper introduces the important concepts of system architecture, including why it is needed and how it has heen developed and applied around the word. In the past, control systems lor road traffic were often installed to provide just one or two services working independently as separate subsystems. In contrast, complex management, control and data-gathering services are provided simultaneously by ITS. While there are risks of a number of subsystems working in conflict with one another, there are significant opportunities for an amalgamation of these subsystems working in synergy. System architecture provides the logical framework, based on user requirements for planning, defining, and integrating intelligent transportation systems. A national or regional system architecture is a formal statement of the national or regional approach to ITS, and the first step on the way to creating detailed designs. In addition, the establishment and use of the ITS architecture adds considerable value to the overall ITS development process in various ways.
