CLASSIFY THE ROAD TRAFFIC DANGER GRADE METHOD AND APPATATUS AND SYSTEM USING FORWARD ROAD STATE INFORMATION, TRAFFIC STATE INFORMATION AND VEHICLE'S VELOCITY INFORMATION

摘要

PURPOSE: A classify the road traffic danger grade method and an apparatus and a system using forward road state information, traffic state information and vehicles velocity information are provided to prevent an accident in advance by supplying an accident index information to a filed in real time. CONSTITUTION: In a classify the road traffic danger grade method and an apparatus and a system using forward road state information, traffic state information and vehicles velocity information, a frictional coefficient DB(130) stores a road friction coefficient according to a road surface state. A road surface state processing unit(120) extracts the road friction coefficient corresponding to the road condition of a current road. . A traffic danger grade generation unit(150) generates traffic danger grade A safe index information provider(160) supplies traffic danger grade as a safe index information type. A frictional coefficient processing unit updates the latest road frictional coefficient into the frictional coefficient DB.
