The traffic control system uses global positioning system information from a variety of vehicles, analyzes that information and uses it to provide control signals to traffic control devices. For example, a base station may use information about vehicle patterns and vehicle speeds to control traffic signals, speed limit indicators, and traffic metering lights. In turn, the base station can provide information back to the vehicle about traffic patterns. This enables the driver to make his or her own determination about vehicle patterns. The traffic pattern information may also be used with a GPS navigator to automatically plot a preferred path around adverse traffic conditions.
