# 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/](https://tensorust.com/datasets/traffic-count-shifts/)**.

## Files here

| file | what it is |
|---|---|
| `sample.csv` | 25 rows of the full file (the same sample shown on tensorust.com) |
| `summary_by_event_type.csv` | row counts by event type across the full file, no entity names (groups with fewer than 3 rows are folded into "Other") |

## Summary by event type (largest groups)

| Event type | rows |
|---|---|
| count | 1,305 |
| view_change | 14 |
| feed_down | 8 |
| feed_up | 8 |
| TOTAL | 1,335 |

Full table: `summary_by_event_type.csv`.

## What the full file has

- 1,335 rows
- Key fields: observed_at, target, event_type, facility, org_oid, trucks, cars, buses, persons, vehicles
- Parquet and CSV, a README with sources, method and limits, and the build script
- Free 25-row sample (no personal contact data)

Coverage: 10 cameras at 10 facilities in California and Georgia; 1,305 counted frames. Frames from 2026-11-06T07:39:17Z to 2026-11-07T01:22:18Z (pilot; grows with every pass)

## 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.
