Tomtom with hd traffic works like that and is excellent.
How does the TJA know if it's on a motorway? Maybe uses the satnav map data?

RTTI uses the moving object information, meaning each BMW wit RTTI, but also some trucks and taxis. So it's very accurate, updated every three minute, using the speeds of the cars on the streets.
For re-routing it will use all its available information as it also gets RTTI for non-highways, so also major streets specifically in cities. So it tries to route you optimally, using all available traffic info.
TJA knows you're on a highway through your GPS position.
