System and method for warning of an upcoming precautionary zone
First Claim
1. A system for warning a driver of a vehicle of an upcoming precautionary zone, the system comprising:
- a light emitter, said emitter being associated with the precautionary zone and emitting a coded light signal;
a receiver for detecting the coded light signal from said emitter, said receiver mounted on the vehicle; and
an alert system for indicating a warning to the driver when said receiver detects the coded light signal from said light emitter, whereby said warning provides an alert of a proximity of the precautionary zone to the driver.

Abstract
A method and system for warning a driver of a vehicle of an upcoming precautionary zone. The system includes a light emitter which emits an infrared coded light signal associated with a precautionary zone. A receiver mounted within the vehicle detects the infrared coded light signal when approaching the precautionary zone. The receiver decodes the light signal and associates the light signal with a specific category of a precautionary zone. The receiver informs an alert system located within the vehicle of the proximity and category of precautionary zone. The alert system provides an indication to the driver of the proximity and category of the precautionary zone. The indication may include a visual, audio, or other electrical indicator providing a warning to the driver.

14. A method of warning a driver of a vehicle of an upcoming precautionary zone, said method comprising the steps of:
-
emitting, by a transmitter associated with the precautionary zone, a coded light signal;
detecting, by a receiver mounted to the vehicle, the coded light signal;
informing, by the receiver, the receipt of the coded light signal to an alert system; and
alerting, by the alert system, a warning of the proximity of the precautionary zone.

19. A system for warning a driver of a vehicle of an excessive speed associated with an upcoming precautionary zone, the system comprising:
-
a light emitter, said emitter being associated with the precautionary zone and emitting a coded light signal for indicating a speed zone associated with the precautionary zone;
a receiver for detecting and decoding the coded light signal from said emitter, said receiver mounted on the vehicle;
a microprocessor for receiving the decoded light signal from the receiver and determining if the vehicle is exceeding the speed limit, said microprocessor located on the vehicle; and
an alert system for providing an indication to the driver of the speed of the vehicle and an excess of the speed limit of the precautionary zone, said alert system receiving a notification from said microprocessor indicating an excess of speed of the vehicle.
