　　Abstract：Advanced Travellers Information System (ATIS) is an important component of Intelligent Transportation Systems (ITS) .The research content mentioned in this paper is the architecture project of ATIS in China. This paper analyzes the state of domestic development of ATIS and summarizes international results in this field. Based on the summary, this paper proposes the urban traffic information system architecture project (UTISAP) suitable for the administerial management situation of China. The UTISAP includes a traffic information center, eight subsystems and two databases. Eight subsystems&nb sp;comprise traffic management, ETC, TFGS, traffic information service, GIS, EMS, CVOS and AHS. Two databases comprise the aspects of road traffic management and vehicles management. And the traffic information center is the core. Finally, the paper forecasts the positive impact after the application of UTISAP.
