Abstract

A system includes a display layer disposed beneath one or more layers of a road that is configured to output light to illuminate an upper surface of the road. One or more vertical cylindrical voids extend from the display layer to the upper surface of the road providing a path for the light from the display layer to reach the upper surface of the road. Circuitry is configured to determine a traffic scheme for the road based on traffic data received from one or more sources. Control signals are issued to the display layer to control illumination of the upper surface of the road in accordance with the traffic scheme. Traffic scheme-specific values are output to a smart vehicle corresponding to one or more smart vehicle algorithms.

First claim

The invention claimed is:

1. A system comprising:
a display layer disposed beneath one or more layers of a road that is configured to output light to illuminate an upper surface of the road;
one or more vertical cylindrical voids extending from the display layer to the upper surface of the road providing a path for the light from the display layer to reach the upper surface of the road; and
circuitry configured to
determine a traffic scheme for the road based on traffic data received from one or more sources,
issue control signals to the display layer to control illumination of the upper surface of the road in accordance with the traffic scheme, and
output traffic scheme-specific values to a smart vehicle corresponding to one or more smart vehicle algorithms.

2. The system of claim 1 , wherein the one or more vertical cylindrical voids are filled with a translucent material allowing light to pass from the display layer to the upper surface of the road.

3. The system of claim 2 , wherein the one or more vertical cylindrical voids include optical fibers that transmit the light from the display layer to the upper surface of the road.

4. The system of claim 1 , wherein a diameter of the one or more vertical cylindrical voids is based on predetermined structural design criteria of the road.

5. The system of claim 1 , wherein a distribution density of the one or more vertical cylindrical voids is based on predetermined structural design criteria of the road.

6. The system of claim 1 , wherein the display layer includes one display surface covering an area of the road.

7. The system of claim 1 , wherein the display layer includes a plurality of individual display surfaces corresponding to locations of the one or more vertical cylindrical voids.

8. The system of claim 1 , wherein the display layer is configured to output one or more colors of light based on received control signals.

9. The system of claim 8 , wherein the circuitry is further configured to determine the one or more colors of the light output by the display layer based on the traffic data.

10. The system of claim 1 , wherein the circuitry is further configured to issue the control signals to the display layer to output predetermined illumination patterns to be displayed on the upper surface of the road.

11. The system of claim 10 , wherein the circuitry is further configured to issue the control signals to the display layer to illuminate the upper surface of the road at one or more lane marker locations based on the traffic scheme.

12. The system of claim 10 , wherein the circuitry is further configured to issue the control signals to the display layer to illuminate the upper surface of the road with one or more images corresponding to advertisements, brands, or notifications.

13. The system of claim 1 , wherein the circuitry is further configured to determine a modified traffic scheme when one or more traffic incidents are present.

14. The system of claim 13 , wherein the circuitry is further configured to determine a cost of implementing the modified traffic scheme based on a change in average vehicle speed or vehicle density.

15. The system of claim 14 , wherein the circuitry is further configured to
implement the modified traffic scheme when the cost of implementing the modified traffic scheme is less than a predetermined threshold; and
maintain a current traffic scheme when the cost of implementing the modified traffic scheme is greater than or equal to the predetermined threshold.

16. The system of claim 1 , wherein the circuitry is further configured to determine the traffic scheme-specific values corresponding to the one or more smart vehicle algorithms associated with the smart vehicle.

17. The system of claim 16 , wherein the circuitry is further configured to determine updated traffic scheme-specific values for the smart vehicle at a frequency based on a speed or location of the smart vehicle.

18. The system of claim 1 , wherein the traffic scheme data includes at least one of a road identifier, traffic scheme boundaries, direction of traffic flow for one or more lanes, lane marker colors, and a speed limit.

19. A method comprising:
determining, via circuitry, a traffic scheme for the road based on traffic data received from one or more sources;
issuing, via the circuitry, control signals to a display layer to control illumination of the upper surface of the road in accordance with the traffic scheme; and
outputting, to at least one smart vehicle, traffic scheme-specific values corresponding to one or more smart vehicle algorithms,
wherein the display layer is disposed beneath one or more layers of a road and is configured to output light to illuminate the upper surface of the road, and one or more vertical cylindrical voids extending from the display layer to the upper surface of the road provide a path for the light from the display layer to reach the upper surface of the road.
