Development of Beijing Regional Intelligent Transportation System architecture

Regional Intelligent Transportation System (ITS) architecture, which is usually developed in accordance with national ITS architecture, provides the framework and guidance for developing and deploying ITS technologies in a region. The development of Beijing Regional ITS Architecture, which is the essential part of the Beijing ITS Strategic Planning, is rather an exploring initiative due to the fact that the China´s national ITS architecture is currently being updated. This paper is intended to present the methodology that has been used in the development of Beijing Regional ITS Architecture. First, the functional needs are analyzed based on a comprehensive survey. Then, the functional needs are mapped to user services as defined and required by the China´s national ITS architecture. The concept of market packages, which is not included in the current version of China´s national ITS architecture but was utilized in the U.S. national ITS architecture, is introduced and applied, with which the user services are converted into market packages. Subsequently, the physical architecture composed of physical entities and architecture flows are developed. Finally, some conclusions are provided and the additional research is recommended.
