Currently available on highways Reported with AlertC for all jams: codes 101, 108, 115 (same as the jam itself) Reported for jams with very small delay (<30 sec), as a result the actual jam

might not appear in the feed, while the warning does.

We report jam tail warnings only for highway jams with a sharp speed drop at the tail / end

Sharp means speed dropping by more than 50 km/h to a speed lower than 30 km/h, all within 500m max

The jam front has to move upstream or be stable, not moving downstream.

Currently testing with jam front prediction.
