Complex operating environment sections were analyzed to determine the risks from geometric line conditions, road facilities' characteristics, traffic environment and climatic environment. Risk Warning System for complex operating environment sections of expressway was designed by five subsystems: Risk information collection and releasing module, RFID based dangerous goods vehicles monitoring module, GIS-based database management module, risk warning module, and driving safety management decision-making aiding module. Based on the safety decision-making model for measurement type and safety speed control standards, which were proposed under various pavements conditions, visibilities and traffic environments, the system is capable of supporting complex operating environment sections of express way risk control, traffic flow coordination and emergency management, etc.
