Abstract: A traffic reporting system and method utilizes wireless technology to efficiently provide traffic information specifically targeted to the user of a wireless unit, such as a cellular phone. Traffic information is detected and received, for a designated region, from a plurality of sensors. Traffic flow information within the designated region is then calculated based upon the sensed information. Finally, the traffic flow information is output to a wireless unit upon the wireless unit entering the designated region. As such, the traffic information can be effectively transmitted to the user through the wireless unit. It can be particularly targeted to the user when entering a particular designated region, such as a cell for example, to advise of heavy traffic within the region.
