Passive pavement-mounted acoustical linguistic drive alert system and method

DETAILED DESCRIPTION This invention provides a method and apparatus for conveying specific messages in the form of words or other audible sounds to the driver and/or other occupants of vehicles, while traveling on a roadway.
A modulation signal can be permanently embedded in the surface of the pavement.
The modulation directly corresponds to spoken words, commands, or other audible messages.
As the vehicle passes over the modulated region, the tires convey the sounds to the cabin of the vehicle.
This conveyance requires no other apparatus on board the vehicle or along the highway.
Thus, once the invention is installed, the method and apparatus can be passive.
Conveying safety and other messages to vehicles passing by can reduce run-off-the-road accidents and alert drivers to other potentially hazardous conditions on interstate and secondary highways.
These, and other, goals and embodiments of the invention will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings.
It should be understood, however, that the following description, while indicating preferred embodiments of the invention and numerous specific details thereof, is given by way of illustration and not of limitation.
Many changes and modifications may be made within the scope of the invention without departing from the spirit thereof, and the invention includes all such modifications.
