Smart Link traffic on two levels; one free giving broadcast updates and the other is a paid upgrade. Not bother to pay for the upgrade but the basic option seems to work OK. It gives estimated time for delays and highlights route on map - orange or red depending on delay. Of course traffic delays use "car based" logic so probably don't affect a bike as much if you filter but you do get an avoid option to recalculate the route if a faster route is possible.
