【Abstract】For the precise and effective prevention of traffic accidents through preemptive warnings, an estimation method for the safety risk of urban road traffic is proposed based on driving behavior obtained from OBD data of vehicles and through information entropy theory. First, the relationship between locations with frequent abnormal driving behavior or places of traffic acc
