Abstract
Apparatus, methods and systems relating to providing vehicular traffic information through a wireless telecommunications network. An exemplary system includes a geographic location system (GLS), a database containing vehicular roadway information, and a vehicular traffic determination node. The GLS is operative to determine the approximate physical location of at least one Mobile Station (MS) in communication with the wireless telecommunications network. The vehicular traffic determination node is operative to i) receive and correlate the approximate physical location of the MS to the vehicular roadway information to generate vehicular traffic information, and ii) communicate the vehicular traffic information to the wireless telecommunications network; the wireless telecommunications network can selectively-transmit or broadcast the vehicular traffic information.
