How fresh the Parking SF parking model is.
Freshness in Parking SF means the model is rebuilt from recent public datasets, not that it claims live curb occupancy.
The planning model is designed around a rolling 90-day lookback for parking meter and 311 parking data, plus the most recent 3 monthly Bay Wheels trip files available when the dataset is rebuilt.
What freshness means here
Parking SF rebuilds from recent public historical inputs so the map reflects current recurring patterns rather than stale archival data. That makes the product more useful for planning week-to-week behavior.
What freshness does not mean
A fresh model is still a planning model. It does not transform public historical data into a live vacancy guarantee, and it should not be described that way.
Why rolling windows matter
Rolling windows let the app react to newer parking and mobility behavior without pretending that every change is visible instantly. The result is a more stable signal for comparing blocks and hours across a normal week.
