【Abstract】 On the basis of function and information models, ITS architecture always plays a key guiding role on ITS technology research, product development, system integration and project implementation. This paper focuses on the comparison of the national ITS architectures used in U.S., E.U. and Japan from different perspectives, such as guidelines, user services, logical architecture, physical architecture and standardization. Some suggestions to the development of our national ITS architecture are then provided.更多还原
