Abstract: A device and method for providing speed limit and other roadway and traffic information to a vehicle. A signal is transmitted from a remote source, such as a satellite, to one or more ground transmitters. The ground transmitters are located apart from each other and adjacent to various sections of roadway, which may include work zones, school zones, residential areas, truck routes, interstate corridors, and highways, or in other vehicles, such as law enforcement and emergency vehicles. The ground transmitters have the necessary hardware and software for receiving and transmitting speed limit and other roadway information. The receiving device has the necessary hardware and software to receive speed limit and other information, and may translate speed information to vehicle components, such as an engine control computer for fuel and/or speed control. The receiver may use various signals audibly and visually to insure a higher level of driver awareness.

Abstract: The need to have speed control and a higher level of driver awareness on our highways is extremely essential, and will improve our American infrastructure. Safety will increase and fuel consumption will decrease dramatically when the Speed Limit Enforcer is implemented. The Speed Limit Enforcer consist of receivers, Ground Transmitters, and Satellite Transmitters. These three major components work in conjunction and depend on each other for maxima performance. The Speed Limit Enforcer's Receiving Device will be located inside vehicle desired. Ground Transmitters will be located in work zones, school zones, residential areas, truck routes, interstate corridors, US and State highways, in or on Federal, Local, and State Government work vehicles, Law Enforcement and Emergency vehicles, etc. Ground Transmitters will have all the necessary electronic components and software making it capable of receiving and transmitting speed limit and zone information.
