In this paper, the Korean intelligent transportation systems (K.ITS) conceptual architecture under development is described as a result of the first year research, which is a 2-year-long research project, started in 1994 as a first step of comprehensive K.ITS programs. The purpose of this project is to develop a national strategic plan for K.ITS development and deployment to reduce traffic problems and enhance national competitiveness. The architecture under development consists of four layers in structure, namely, application, common information, communication, and monitoring/control equipment. The top layer, which is called "application layer" is divided further into two levels: the upper level contains advanced traveler information systems, autonomous route guidance systems, etc., and the lower level contains advanced traffic management systems, infrastructure-based dynamic route guidance systems, and advanced policing information systems. The reason is that the lower level of the top layer and three other layers are characterized as an infrastructure of K.ITS and the upper level of the top layer as a superstructure. A basic framework of K.ITS architecture is under development, which is described conceptually hereinafter. For the application of nationwide ITS services, three levels of system architecture are being considered. One is for an urban level that is based on jurisdictional boundaries. Another is for a rural level that is outside of all urban areas and a third is for a regional level that covers services in large metropolitan areas. Each infrastructure communicates each others horizontally without any hierarchy for integrated services. Within this framework, superstructure level of services, such as traffic information broadcasting system and autonomous route guidance system, are dedicated to urban or rural level of infrastructure so that more accurate dynamic traffic information is provided and cost-effectiveness is achieved. Other services, such as pre-trip service, can be dedicated to the regional level of infrastructures so that more integrated services can be provided. In summary, a conceptual framework of K.ITS architecture was proposed and will be further explored by the end of 1995.
