Facility Traffic Camera Counts: free sample (Tensorust LLC)

Truck and car counts every 15 minutes at 10 ports and plants from public DOT camera stills that the DOTs themselves never archive.

Headline: Caltrans says its traffic camera stills are neither retained nor archived, and 511GA keeps no history either, so activity at a port gate or plant exit leaves no public record.

This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 1,335 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/traffic-count-shifts/.

Method and limits

Each pass fetches the current still (and for Caltrans up to 12 earlier stills), stores it, and counts objects with YOLO11. A view check correlates each frame with reference views of that camera; when the operator has panned or zoomed, the frame is flagged view_ok=false and excluded from the running median. Shift = this frame's count minus the camera's running median of in-view frames so far. Caltrans times are the image capture time; Georgia times are fetch time.

Not a DOT traffic counter (it is computer vision on camera stills) and not a measure of a facility's output: nine of the ten views show the public road at or near a facility, and most traffic on it is not caused by the facility. Night and weather lower detection. Early pilot with under a day of history; shifts become meaningful as weeks accumulate. No faces or plates are read or stored as data.
