Research on electronical information source reconstructing traffic accident

It is required that the traffic accident reconstruct should reflect the current status as real as possible with the model. However, this method exists a certain error. With the direct source providing accident information, it can reconstruct the accident accurately and provide the devices directly extracting the accident information, including vehicle-mounted GPS, accident data recorder, automobile data recorder and road monitoring video. This paper discusses the structure, working principle, extracting information category and data error of these devices, and research the application of these data in the accident reconstruct.
