Traffic data services without navigation system

摘要

A non-navigation data system for providing traffic data service in a mobile environment can include a data decoder for decoding a digital data stream from a digital audio radio transmission source, location determining means (such as GPS or cellular location determining schemes) for determining a current location of a mobile receiver receiving the digital data stream, a display for displaying traffic data corresponding to the current location, and a plurality of static maps wherein the traffic data corresponding to the current location is overlaid at least over a portion of the static maps.
