Black spots are inevitable on expressways, and improving the level of safety service is a key issue in expressway operation. Since road safety improvement by engineering manners showed the limitations of the high cost, the development of intelligent transportation technology has made accident prevention on expressway black spots possible. Based upon identification of expressway black spots, safety evaluation of traffic condition as well as the analysis of accident processes, this paper divides Accident-prone locations into two categories, locates the accident precursors of black spots and extracts the characteristic variables of forewarning accidents so as to set up a computational model of DMS's setting, brings forward the principles of information distribution and designs a data base of accident prevention. Finally, it establishes the accident prevention system of expressway black spots composed of traffic information collection, risk status judgment, pre-warning information distribution and communication.
