  • System and method for warning of an upcoming precautionary zone
    Publication number: 20020175829
    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.
