Abstract

Drivers are required to abide by speed limits. However, the driver must know what the speed limit is on any given street in order to abide by this law. Speed limit signs have been known to be few and far between on certain streets. Even on streets embellished with speed limit signs, drivers often "miss" one and must wait for the next sign in order to know if they are in danger of speeding or wasting their time at a lower than required speed limit. This can annoy drivers and be a danger in many cases.

Method of Obtaining Speed Limit with GPS

The invention disclosed proposes a solution that allows drivers to determine the speed limit at their exact location.

Drivers are required to abide by speed limits. However, the driver must know what the speed limit is on any given street in order to abide by this law. Speed limit signs have been known to be few and far between on certain streets. Even on streets embellished with speed limit signs, drivers often "miss" one and must wait for the next sign in order to know if they are in danger of speeding or wasting their time at a lower than required speed limit. This can annoy drivers and be a danger in many cases.

This invention discloses a solution that allows drivers to determine the speed limit at their exact location. Drivers will not have to wait for the next posting of a speed limit. Consequently, drivers will always be aware of the posted speed limit.

The posted speed limit for point X on street Y can be determined through GPS technology. Since GPS allows for the exact location of a vehicle to be determined, this location can be mapped to the speed limit posted for that point X of the street Y.

The speed limit for any given street can be stored on any standard GPS receiver, much like one that is found in a car, truck, or mobile GPS unit. The information on all streets may be pre-loaded on the GPS device in the same way that street information from all over the world is stored. The positional data transmitted from...
