ABSTRACT:
Methods and apparatus for storing, accessing, generating and using information about speed limits and speed traps are described. The system includes a positional sensor such as a GPS device. Position information is used to access a database of speed limit and/or speed trap information. The database may be local or remote. Access to a remote database may be achieved using a wireless communications device such as a wireless (cellular) modem. Encountered speed traps are logged in response to the activation of a speed trap alert button by a user of the device or the output of a radar/laser detector. Speed trap position, date and time information is transmitted to the remote database system. Speed limit information is used to control the speed of the automobile as part of a cruise control operation and/or is used to provide the motor vehicle operator with warnings, e.g., that the applicable speed limit is being exceeded. Speed trap information which is retrieved using positional information provided by the GPS device is used to warn the user of the device of speed traps in the user's vicinity as the user approaches the location of the known speed trap.
