Do you know for a fact that that's what Google uses for traffic info on Google
Maps?
The frequency at which it updates for me doesn't seem like it'd be usable for traffic estimation.
- crazygringo 1y agoThe higher-resolution frequency surely comes from people who have Google Maps open while they drive, for directions. Also, slow traffic is slow. If you're stuck in gridlock, even if your location only updates once every 5 minutes, that might just be 5 blocks. Average that across a quarter of all vehicles and that should be plenty of data for block-level traffic estimation.
- rkomorn 1y agoGetting more data from people actively using maps makes sense. Where I live, between updates I see on location tracking (when not actively using maps), you can even walk different routes from one point to another. That's why I've had the feeling that the frequency for traffic must be higher than the frequency for location / timeline tracking.
