Fig 9

Scatterplot and linear regression of aggregated manual counting versus computer vision supported counting of both video-clip and digital-stills across nine observation periods at six bridge sites in November 2019.

Manual and computer counts are aggregated at 60 minute intervals and show strong overall correlation (R² = 0.89).
