Abstract

A vehicle guidance system (VGS) facilitates interaction between human operated vehicles (HOV), autonomous driverless vehicles (ADV), and/or semi-autonomous vehicles, on the roadway, allowing safe interface with each other and with other elements, for example, weather conditions, traffic control systems, road conditions, obstructions that enter the roadway (people, rocks, animals, debris falling onto roadway from other vehicles), etc. The system provides guidance, communication, and control for the vehicles on the roadway, by using a solar-powered system comprising post assemblies having solar panel(s), sensors, forward and/or downward lighting, and other indicators/alarms to signal to the vehicle or driver regarding road, bridge, weather, accident, speeding, or other conditions of concern in the vicinity for safety and/or operability of the vehicle/driver(s).

Claims

1. A vehicle guidance system comprising a network of sensors and indicators extending along a roadway being traveled by a vehicle, the network comprising:

multiple post assemblies spaced along the roadway, each holding at least one light module that illuminates a portion of the roadway forward from the post assembly, the post assembly being less than 5 feet tall;

a sensor array for sensing ambient or environmental conditions at or near at least one of said post assemblies and on or near the roadway along which the post assemblies are spaced, wherein at least one or more sensors of the sensor array activate the network based on light, wind, or vibration of an approaching vehicle;

a sensor communication/electronic-signaling network that signals at least one indicator of the ambient or environmental conditions, wherein the at least one indicator may be said at least one notification LED on one more of the post assemblies, a flashing or blinking light, an audible alarm, a digital sign, a signal to an on-vehicle alarm, a signal to an on-vehicle monitor, a signal to an on vehicle video screen, and another visual or audible signal; and

wherein activation of a sensor, of the sensor array, on multiple, adjacent post assemblies causes communication between the post assemblies to relay info about road conditions such as ice, rain, road damage, bridge damage, and other conditions.

2. The system of claim 1, wherein each post assembly comprises a solar panel.

3. The system as in claim 1, further comprising solar-powered roadway markers.

4. The system as in claim 1 comprising at least one solar panel on at least one of the post assembly so the system is solar-powered and autonomous, so that the system requires no utility power grid connection.

5. The system as in claim 1, wherein activation of a sensor, of the sensor array, on multiple, adjacent post assemblies causes communication between the post assemblies to relay info about direction and speed of travel of vehicles on the roadway, informing approaching vehicles of a need to slow down or stop.

6. The system as in claim 1, wherein the post assemblies are illuminated a quarter of a mile ahead of the travel of the vehicle, lighting ahead of the vehicle.

7. The system as in claim 6, wherein the at least one notification LED remains “

ON”

when there are no vehicles on the road.

8. The system as in claim 1, wherein, said at least one light module on each post assembly being on, and with vehicles passing between opposite post assemblies, a light pathway of said at least one light on each post assembly is interrupted and a motion of the vehicle is identified thereby.

9. The system as in claim 1, wherein, as the vehicle passes between multiple post assemblies, the system determines the speed and direction of the vehicle.

10. The system as in claim 1, wherein the vehicle'"'"'s headlights will activate the system, and the system is in a dormant or energy-saving mode until the activation by the headlights of an oncoming vehicle.

11. The system as in claim 1, wherein said one or more sensors of the sensor array are selected from motion sensors, vibration sensors, and anemometers that detect the wind created by passing vehicles.

12. The system as in claim 1, wherein said at least one light of the light module illuminates a portion of the roadway forward and away from an approaching vehicle.

13. The system as in claim 1, wherein said at least one light of the light module illuminates a portion of the roadway forward, downward, and away from an approaching vehicle.

14. The system as in claim 1, wherein said at least one light of the light module illuminates a portion of the roadway forward, downward, and away from an approaching vehicle, illuminating an area on the roadway/ground of less than 50 square feet, less than 100 square feet, less than 200 square feet, or less than 300 square feet.

15. The system of claim 1, wherein the at least one light of the light module is focused downward, forward and away from a vehicle approaching the at least one light on a side of the roadway nearest the at least one light of the light module.
