will take the shortest time) for that vehicle, given the
current location of the vehicle, based on global positioning
system (GPS) information, and a desired destination input by
the user at an input source 25 located in the vehicle. As
disclosed by Ayanoglu, in a preferred embodiment,
traffic information is periodically updated to the
central database 50 whereby mobile users
periodically transmit their respective position and
speed to the central database 50. The central
database 50 is configured to then average the
aforementioned received information provided by the
mobile users so as to determine the average speed
rate on various traffic routes. Preferably, each
mobile user is enabled to initiate the minimum path
information, and by notifying the central database
50 of its position and its destination, the mobile
user can obtain the best route information from the
central database 50. Still further, the transmitted
wireless message from each mobile user may include
any known type of information such as differential
correction information from the GPS receiver 26
[column 3, line 64, to column 4, line 10].
Based on the above disclosure, it is clear that Ayanoglu
discloses a method comprising developing GPS information about
a plurality of vehicles, analyzing traffic patterns (i.e.,
determining the average rate of speed on various traffic
routes) based on the GPS information and transmitting route
information to vehicles based, at least in part, on the
traffic patterns. Ayanoglu also broadly contemplates use of
