Intelligent traffic management for vehicle platoons

1. A road controller system including a plurality of road controllers, comprising:

a data store to store an active traffic policy, the active traffic policy including rules to control traffic in a controlled area to reduce noise pollution of vehicle platoons;

a sensor array interface to receive sensor data, the sensor data including road condition data;

a processor subsystem to:

access a status message received from a vehicle platoon traveling on an area controlled by a road controller of the plurality of road controllers in the road controller system, the status message including a platoon identifier and a number of vehicles in the vehicle platoon, and the status message transmitted to the road controller when the vehicle platoon enters the area controlled by the road controller;

determine a platoon size of the vehicle platoon based on the status message received from the vehicle platoon;

determine a change to the platoon size of the vehicle platoon, the change to the platoon size based on the active traffic policy and the road condition data; and

cause transmission of a control message to the vehicle platoon to implement the change to the platoon size of the vehicle platoon.

2. The system of claim 1 , wherein the active traffic policy is updated from a road controller broker.

3. The system of claim 2 , wherein the processor subsystem is to:

determine that the road controller broker is unavailable; and

activate a default policy as the active traffic policy when the road controller broker is unavailable.

4. The system of claim 1 , wherein the active traffic policy is managed by the road controller system.

5. The system of claim 1 , wherein the active traffic policy is accessed from a road controller broker, the road controller broker controlling the plurality of road controllers in the road controller system.

6. The system of claim 1 , wherein the rules to control traffic in the controlled area include rules to control traffic in a residential area to reduce noise pollution of vehicle platoons operating in the residential area.

7. The system of claim 1 , wherein the sensor data further includes weather data, and wherein the determined change to the platoon size is further based on the weather data.

8. A method of operating a platoon with a road controller system, performed by a road controller of a plurality of road controllers in the road controller system, the method comprising:

accessing an active traffic policy, the active traffic policy including rules to control traffic in a controlled area to reduce noise pollution of vehicle platoons;

receiving sensor data from a sensor array interface of the road controller system, the sensor data including road condition data;

receiving a status message received from a vehicle platoon traveling on an area controlled by the road controller, the status message including a platoon identifier and a number of vehicles in the vehicle platoon, and the status message transmitted to the road controller when the vehicle platoon enters the area controlled by the road controller;

determining a platoon size of the vehicle platoon based on the status message received from the vehicle platoon;

determining a change to the platoon size of the vehicle platoon, the change to the platoon size based on the active traffic policy and the road condition data; and

transmitting a control message to the vehicle platoon to implement the change to the platoon size of the vehicle platoon.

9. The method of claim 8 , wherein the active traffic policy is updated from a road controller broker.

10. The method of claim 9 , further comprising:

determining that the road controller broker is unavailable; and

activating a default policy when the road controller broker is unavailable.

11. The method of claim 8 , wherein the active traffic policy is managed by the road controller system.

12. The method of claim 8 , further comprising:

accessing the active traffic policy from a road controller broker, the road controller broker controlling the plurality of road controllers in the road controller system.

13. The method of claim 8 , wherein the rules to control traffic in the controlled area include rules to control traffic in a residential area to reduce noise pollution of vehicle platoons operating in the residential area.

14. The method of claim 8 , wherein the sensor data includes weather data, and wherein determining the change to the platoon size of the vehicle platoon comprises using the weather data to determine the change.

15. The method of claim 8 , wherein the sensor data includes road condition data, and wherein determining the change to the platoon size of the vehicle platoon comprises using the road condition data to determine the change.

16. At least one non-transitory machine-readable medium, including instructions for operating a platoon with a road controller system, which when executed on a machine for a road controller of a plurality of road controllers in the road controller system, cause the machine to perform the operations comprising:

accessing an active traffic policy, the active traffic policy including rules to control traffic in a controlled area to reduce noise pollution of vehicle platoons;

receiving sensor data from a sensor array interface of the road controller system, the sensor data including road condition data;

receiving a status message received from a vehicle platoon traveling on an area controlled by the road controller, the status message including a platoon identifier and a number of vehicles in the vehicle platoon, and the status message transmitted to the road controller when the vehicle platoon enters the area controlled by the road controller;

determining a platoon size of the vehicle platoon based on the status message received from the vehicle platoon; and

determining a change to the platoon size of the vehicle platoon, the change to the platoon size based on the active traffic policy and the road condition data; and

transmitting a control message to the vehicle platoon to implement the change to the platoon size of the vehicle platoon.

17. The machine-readable medium of claim 16 , wherein the active traffic policy is updated from a road controller broker.

18. The machine-readable medium of claim 17 , further comprising:

determining that the road controller broker is unavailable; and

activating a default policy when the road controller broker is unavailable.

19. The machine-readable medium of claim 16 , wherein the active traffic policy is managed by the road controller system.

20. The machine-readable medium of claim 16 , further comprising:

accessing the active traffic policy from a road controller broker, the road controller broker controlling the plurality of road controllers in the road controller system.

21. The machine-readable medium of claim 16 , wherein the rules to control traffic in the controlled area include rules to control traffic in a residential area to reduce noise pollution of vehicle platoons operating in the residential area.

22. The machine-readable medium of claim 16 , further comprising receiving sensor data from a sensor array interface incorporated in the road controller system.
