San Francisco traffic lights green/yellow/red timings

Question

Where would one go about finding data for traffic lights?

For example, scheduled timings as well as actual (historical) timings.

(San Francisco)

To be clear, you are not looking for latitude/longitude of the traffic lights (which can be found on OpenStreetMap), but only for when each light was/will be green/yellow/red, right? — Nicolas Raoul, Commented Jan 5, 2023 at 8:12
@NicolasRaoul, Yepp, I need it to produce (very) accurate traffic predictions. — Pacerier, Commented Jan 6, 2023 at 21:44

Traffic Technology Services provides live traffic light status (red, yellow , green, etc...) data. For San Francisco, it might be available via https://datasf.org/
