Methods identifying vehicles and related systems, controllers, and vehicles

1. A method of operating an intelligent transportation system, the method comprising:

obtaining first traffic information from a first source, wherein the first traffic information includes position information for a first vehicle and first position information for a second vehicle, wherein the first traffic information is generated independently of the first vehicle;

obtaining second traffic information from a second source, wherein the second traffic information includes second position information for the second vehicle, wherein the second traffic information omits position information for the first vehicle, wherein the second vehicle is collaborative with respect to the intelligent transportation system such that the second vehicle supports communication with the transportation system controller, and wherein the second source includes the second vehicle so that the second position information for the second vehicle is based on a communication transmitted from the second vehicle;

responsive to comparing the first traffic information and the second traffic information, identifying the first vehicle as being non-collaborative with respect to the intelligent transportation system such that the first vehicle does not support communication with the transportation system controller; and

providing traffic coordination based on a position of the first vehicle, based on a position of the second vehicle, and based on identifying the first vehicle as being non-collaborative with respect to the intelligent transportation system, wherein providing traffic coordination comprises determining a number and/or percentage of vehicles that are non-collaborative with respect to the intelligent transportation system such that the vehicles that are non-collaborative with respect to the intelligent transportation system do not support communication with the transportation system controller, and generating a warning responsive to the number and/or percentage of vehicles that are non-collaborative with respect to the intelligent transportation system exceeding a threshold, wherein the warning includes the number and/or percentage of vehicles that are non-collaborative.

2. The method of claim 1 , wherein providing traffic coordination comprises generating a dynamic map including information identifying positions, speeds, and/or directions of travel of the first vehicle and the second vehicle.

3. The method of claim 1 , wherein providing traffic coordination comprises controlling a roadside sign and/or traffic light to provide the warning as a visual warning.

4. A transportation system controller of an intelligent transportation system, the transportation system controller comprising:

a network interface configured to communicate with a roadway communication node and a vehicle detection sensor; and

a processor coupled to the network interface, wherein the processor is configured to perform operations comprising:

obtaining first traffic information from a first source, wherein the first traffic information includes position information for a first vehicle and first position information for a second vehicle, and wherein the first traffic information is generated independently of the first vehicle;

obtaining second traffic information from a second source, wherein the second traffic information includes second position information for the second vehicle, wherein the second traffic information omits position information for the first vehicle, wherein the second vehicle is collaborative with respect to the intelligent transportation system such that the second vehicle supports communication with the transportation system controller, and wherein the second source includes the second vehicle so that the second position information for the second vehicle is based on a communication transmitted from the second vehicle;

responsive to comparing the first traffic information and the second traffic information identifying the first vehicle as being non-collaborative with respect to the intelligent transportation system such that the first vehicle does not support communication with the transportation system controller; and

providing traffic coordination based on a position of the first vehicle, based on a position of the second vehicle, and based on identifying the first vehicle as being non-collaborative with respect to the intelligent transportation system, wherein providing traffic coordination comprises determining a number and/or percentage of vehicles that are non-collaborative with respect to the intelligent transportation system such that the vehicles that are non-collaborative with respect to the intelligent transportation system do not support communication with the transportation system controller, and generating a warning responsive to the number and/or percentage of vehicles that are non-collaborative with respect to the intelligent transportation system exceeding a threshold, wherein the warning includes the number and/or percentage of vehicles that are non-collaborative.

5. The transportation system controller of claim 4 , wherein identifying the first vehicle as being non-collaborative with respect to the intelligent transportation system comprises identifying the first vehicle as being non-collaborative based on inclusion of the position information for the first vehicle in the first traffic information and omission of position information for the first vehicle from the second traffic information.

6. The transportation system controller of claim 4 , wherein the second traffic information includes position information for a plurality of vehicles based on respective communications transmitted from the plurality of vehicles without including position information for the first vehicle.

7. The transportation system controller of claim 4 , wherein the communication transmitted from the second vehicle is a V2X communication transmitted from the second vehicle over a wireless interface.

8. The transportation system controller of claim 4 , wherein the first traffic information generated independently of the first vehicle is based on video information.

9. The transportation system controller of claim 4 , wherein the first traffic information generated independently of the first vehicle comprises information generated based on a sensor on and/or embedded in a roadway.

10. The transportation system controller of claim 4 , wherein the first traffic information generated independently of the first vehicle comprises information generated at the second vehicle and/or information generated at a third vehicle.

11. The transportation system controller of claim 10 wherein the information generated at the second vehicle and/or the third vehicle is provided using a V2X communication transmitted from the second vehicle and/or the third vehicle over a wireless interface.

12. The transportation system controller of claim 4 , wherein providing traffic coordination comprises transmitting a traffic coordination communication to the second vehicle and/or to another vehicle.

13. The transportation system controller of claim 4 , wherein providing traffic coordination comprises controlling a roadside sign and/or traffic light to provide the warning as a visual warning.

14. The transportation system controller of claim 4 , wherein providing traffic coordination comprises generating a dynamic map including information identifying positions, speeds, and/or directions of travel of the first vehicle and the second vehicle.
