The big issue preventing me from using something like OsmAnd is my need for real-time traffic. Generally, I can figure out where a place is with only the address since the N-S streets in my city are numbered and the first digits of an address on a cross-street corresponds to the numbered Avenues. Traffic, OTOH, can easily vary by 30 minutes on a 15 mile trip day to day even without any crashes along the route.

Is there an open, or at least more private, app that can give me accurate traffic data?
