The device includes a locational information module for determining location information and speed; a storage module for storing at least one geographic map including at least one route and a speed limit for the at least one route; a processing module configured to receive the location information, retrieve at least one geographic map based on the location information, determine a speed limit based on the location information and compare the speed of the device to the determined speed limit; and a display module for alerting a user if the speed of the device exceeds the determined speed limit. The system and method can be for communicating a subject vehicle's speed to a central server where it can be utilized to analyze traffic congestion patterns or notify selected companies or individuals. ## Claims ### Claim 1 A method of controlling speed of a vehicle, the method comprising: determining, by a computing device located within a vehicle, information about the vehicle, the information including a speed of the vehicle and a location of the vehicle; determining, by the computing device, a threshold speed associated with the location of the vehicle; and in response to determining by the computing device that the speed of the vehicle is greater than the threshold speed, reducing, by the computing device, the speed of the vehicle to be below the threshold speed. ### Claim 2 (depends on 1) The method of claim 1, wherein reducing the speed of the vehicle to be below the threshold speed includes transmitting a control signal to an on-board processor of the vehicle to lower the speed of the vehicle. ### Claim 3 (depends on 1) The method of claim 1, wherein determining the threshold speed associated with the location of the vehicle includes determining a speed limit associated with the location. ### Claim 4 (depends on 3) The method of claim 3, wherein determining the speed limit associated with the location includes determining a last speed limit indication passed by the vehicle. ### Claim 5 (depends on 4) The method of claim 4, further comprising: determining a period of time or distance since passing the last speed limit indication; and presenting a warning in response to determining that the period of time or distance since passing the last speed limit indication is greater than a predetermined period of time or distance. ### Claim 6 A non-transitory computer-readable medium having instructions stored thereon that, in response to execution by a computing device located within a vehicle, cause the computing device to perform actions comprising: determining information about the vehicle, the information including a speed of the vehicle and a location of the vehicle; determining a threshold speed associated with the location of the vehicle; and in response to determining that the speed of the vehicle is greater than the threshold speed, reducing the speed of the vehicle to be below the threshold speed. ### Claim 7 (depends on 6) The computer-readable storage medium of claim 6, wherein reducing the speed of the vehicle to be below the threshold speed includes transmitting a control signal to an on-board processor of the vehicle to lower the speed of the vehicle. ### Claim 8 (depends on 6) The computer-readable storage medium of claim 6, wherein determining the threshold speed associated with the location of the vehicle includes determining a speed limit associated with the location. ### Claim 9 (depends on 8) The computer-readable storage medium of claim 8, wherein determining the speed limit associated with the location includes determining a last speed limit indication passed by the vehicle. ### Claim 10 (depends on 9) The computer-readable storage medium of claim 9, wherein the actions further comprise: determining a period of time or distance since passing the last speed limit indication; and presenting a warning in response to determining that the period of time or distance since passing the last speed limit indication is greater than a predetermined period of time or distance. ### Claim 11 A computing device located within a vehicle and configured to: determine information about the vehicle, the information including a speed of the vehicle and a location of the vehicle; determine a threshold speed associated with the location of the vehicle; and reduce the speed of the vehicle to be below the threshold speed in response to determining that the speed of the vehicle is greater than the threshold speed. ### Claim 12 (depends on 11) The computing device of claim 11, wherein reducing the speed of the vehicle to be below the threshold speed includes transmitting a control signal to an on-board processor of the vehicle to lower the speed of the vehicle. ### Claim 13 (depends on 11) The computing device of claim 11, wherein determining the threshold speed includes determining a speed limit associated with the location. ### Claim 14 (depends on 13) The computing device of claim 13, wherein determining the speed limit associated with the location on the map includes determining a last speed limit indication passed by the vehicle. ### Claim 15 (depends on 14) The computing device of claim 14, further configured to: determine a period of time or distance since passing the last speed limit indication; and present a warning in response to determining that the period of time or distance since passing the last speed limit indication is greater than a predetermined period of time or distance.
