The invention belongs to the field of driverless cars and particularly relates to a driverless car accident handling system and method. The system comprises a cloud side, an accident car driving record terminal, a nearby car driving record terminal, a mobile terminal and an urban road management center. By networking all multi-dimensional data records recording an accident in an effective range and an effective time period of the traffic accident and performing preliminary analysis and classification on the data, a simulated restoration site is formed, analysis of a large amount of data by manpower can be avoided, and the time for processing information is shortened. Compared with existing handling methods, the method has the advantages that the collected data not only contains the information of a black box carrier but also contains the information of other nearby cars, mobile phones of passers-by, road monitoring, navigation data, traffic lights and the like, and the evidence is morecomplete. Through networking, the data can be transmitted to the transportation department and an insurance company in the first time, and the transportation department and the insurance company canhandle the accident more timely.
