  • Traffic data integration method and traffic data integration apparatus
    Patent number: 9723579
    Abstract: A traffic data integration method includes: obtaining, by using a computer, pieces of frame data having a same data pattern between first and second traffic data collected respectively by first and second capture devices that capture, as traffic data, frame data communicated by a node in a network; performing, by using the computer, a time correction process by which a time of each piece of frame data in the first and second traffic data is corrected so that capturing times of pieces of obtained frame data are identical; using, by using the computer, frame data for which a same data pattern does not appear repeatedly in a same capture device, as frame data for performing the time correction process; and restricting, by using the computer, a time difference of frame data used when the time correction process is performed.
