Architecture Research for Highway Network Management and Emergency Management System

This paper discusses the architecture research for a Highway Network Management and Emergency Management System (HNMEM) as established by the Ministry of Transport of the People’s Republic of China (MOT). The HNMEM is part of the ‘eleventh five-year’ plan (2006-2010), which includes programs to improve highway efficiency, safety and emergency response, and provide better travel service to the public. The authors describe the architecture for HNMEM, including function lists, logical architecture, and physical architecture. And, as one of the provincial demonstrations under construction, the Beijing Highway Network Management and Emergency System is introduced. The components of this system include: a traffic flow data management system (based on more than 100 existing traffic flow detectors); a highway video collection and management system (about 60 cameras will be newly constructed, and there are already 100 cameras in place); highway weather information and wet/ice pavement detection system (30 sets of detectors); in-vehicle system of patrol vehicle for highway administration management (about 40 sets of in-vehicle systems); in-vehicle system of highway maintenance patrol vehicle (10 patrol vehicle equipped with maritime affairs satellite communication facility to allow transmitting video, and 10 in-vehicle system will be equipped); highway administration management system; highway maintenance management system; highway network monitoring and emergency management system (including municipal system and 10 district/county systems); highway comprehensive information management system; VMS subsystem; highway traveler information service website system; communication network subsystem; and a safety management subsystem.
