Prioritized vehicle messaging
A computer includes a processor, and a memory storing instructions such that the processor. The processor is programmed to detect a plurality of objects proximate to an infrastructure node. The processor is further programmed to determine respective priorities for each of the objects based on respective characteristics of the objects; and include the objects in a wireless message to a vehicle based on the priorities.
1. A computer comprising a processor, and a non-transitory memory storing instructions such that the processor is programmed to:
detect a plurality of objects proximate to an infrastructure node; determine respective priorities for each of the objects based on respective characteristics of the objects;
generate a message for radio frequency communications including data representing two or more of the plurality of respective objects, wherein the data is ordered in a sequence within the message according to the respective priorities of the two or more objects wherein data representing the highest priority object precedes data representing the lowest priority object such that the data representing the highest priority object is broadcast first and the data representing the lowest priority object is broadcast last; and
broadcast the message via the radio frequency communications.
2. The system of claim 1 , wherein the characteristics include a type of object.
3. The system of claim 2 , wherein the type of object is one of a group including an on-duty vehicle, a not on-duty vehicle, a bicycle, a scooter and a pedestrian.
4. The system of claim 1 , wherein the characteristics include a speed of the object.
5. The system of claim 1 , further comprising an intersection, wherein, the characteristics include one of entering or exiting the intersection.
6. The system of claim 1 , where the characteristics include a likelihood that an object will violate a traffic regulation.
7. The system of claim 1 , wherein the characteristics include a time to reaching a stop line at an intersection.
8. The system of claim 1 , wherein the computer is further programmed to:
receive a status of a component of the object; and
calculate the priority of the object based on the status of the component.
9. The system of claim 8 , wherein the object is a vehicle, and the component is one selected from a group of an emergency brake system, an anti-lock brake system and an electronic stability control system.
10. The system of claim 1 , wherein the computer is further programmed to:
receive a status of a traffic light at an intersection, wherein calculating the priority to include the objects in the wireless message is further based on the status of the traffic light.
11. A method comprising:
detecting a plurality of objects proximate to an infrastructure node;
determining respective priorities for each of the objects based on respective characteristics of the objects;
generating a message for radio frequency communications including data representing two or more of the plurality of respective objects, wherein the data is ordered in a sequence within the message according to the respective priorities of the two or more objects wherein data representing the highest priority object precedes data representing the lowest priority object such that the data representing the highest priority object is broadcast first and the data representing the lowest priority object is broadcast last; and
broadcasting the message via the radio frequency communications.
12. The method of claim 11 , wherein the characteristics include a type of object.
13. The method of claim 12 , wherein the type of object is one of a group including an on-duty vehicle, a not on-duty vehicle, a bicycle, a scooter and a pedestrian.
14. The method of claim 11 , wherein the characteristics include a speed of the object.
15. The method of claim 11 , wherein, the characteristics include one of entering or exiting an intersection.
16. The method of claim 11 , where the characteristics include a likelihood that an object will violate a traffic regulation.
17. The method of claim 11 , wherein the characteristics include a time to reaching a stop line at an intersection.
18. The method of claim 11 , further comprising:
receiving a status of a component of the object; and
calculating the priority of the object based on the status of the component.
19. The method of claim 18 , wherein the object is a vehicle, and the component is one selected from a group of an emergency brake system, an anti-lock brake system and an electronic stability control system.
20. The method of claim 11 , further comprising:
receiving a status of a traffic light at an intersection, wherein calculating the priority to include the objects in the wireless message is further based on the status of the traffic light.
