To provide a method and a device for creating an elaborate traffic scenario in a virtual travel environment on the basis of actual travel data.SOLUTION: A traffic scenario creation device inputs travel data into a situation analyzing device to extract travel environment information in a state where travel data has been acquired by using detailed traffic data corresponding to sequential traffic data collected from a sensor of a data collection vehicle of prior traffic data and an actual travel environment, which correspond to discrete traffic data extracted from existing travel video image by a video image base ADAS, and extracts vehicle state information for an own vehicle by inputting the travel data with a vehicle information extraction device to create a sequential traffic log with a travel sequence. Then, by inputting the sequential traffic log to a scenario enhancement network and using a critical event with a prior scenario enhancement network, the prior sequential traffic log is enhanced, the traffic scenario is verified, and the traffic scenario is mapped to a traffic simulation.SELECTED DRAWING: Figure 2
