Abstract
An infrastructure node and a method of using the node. The node may comprise a processor and memory. The memory may store instructions executable by the processor that include, to: identify a hazard to a target vehicle; and based on the identification, transmit a private message to the target vehicle using a line-of-sight (LOS) transmission.
Claims20
An infrastructure node, comprising:
- a plurality of transmitters each utilizing a different line-of-sight (LOS) channel;
- a processor communicatively coupled to the plurality of transmitters;
- and
- memory storing instructions, executable by the processor, that comprise, to:
- broadcast at least one public message to a plurality of recipients, wherein the plurality of recipients comprise a plurality of target vehicles;
- identify at least one hazard to the plurality of target vehicles;
- determine that a quantity of the plurality of target vehicles exceeds a threshold;
- and
- based on the identification and the determination, transmit a first quantity of private messages via the plurality of transmitters wherein the first quantity is the same as the threshold and broadcast a remaining quantity of private messages;
- wherein the at least one public message comprises static-hazard data, wherein static-hazard data comprises data pertaining to stationary or fixed objects or stationary or fixed obstructions which have a statistical likelihood of coming into contact with at least one of the plurality of recipient vehicles, causing injury to a passenger of the at least one of the plurality of recipient vehicles, or to causing injury to a bystander;
- wherein each of the first quantity of private messages and each of the remaining messages comprise dynamic-hazard data, wherein dynamic-hazard data comprises data pertaining to moving objects or moving obstructions which, as a result of a predicted path of the target vehicle, have a statistical likelihood of at least one of the following:
- coming into contact with the target vehicle, causing injury to a passenger of the target vehicle, causing injury to a bystander, or causing injury to a passenger of another vehicle.

A method, comprising:
- from an infrastructure node comprising a plurality of transmitters each utilizing a different line-of-sight (LOS) channel:
- broadcasting at least one public message to a plurality of recipients, wherein the plurality of recipients comprise a plurality of target vehicles;
- determining a blind spot region for a target vehicle, wherein the target vehicle is one of the plurality of recipients;
- identifying that a likelihood of at least one collision event with an object in the region;
- determine that a quantity of the plurality of target vehicles exceeds a threshold;
- and
- based on the identification and the determination, transmitting a first quantity of private messages via the plurality of transmitters wherein the first quantity is the same as the threshold and broadcasting a remaining quantity of private messages;
- wherein the at least one public message comprises static-hazard data, wherein static-hazard data comprises data pertaining to stationary or fixed objects or stationary or fixed obstructions which have a statistical likelihood of coming into contact with at least one of the plurality of recipient vehicles, causing injury to a passenger of the at least one of the plurality of recipient vehicles, or to causing injury to a bystander;
- wherein each of the first quantity of private messages and each of the remaining messages comprise dynamic-hazard data, wherein dynamic-hazard data comprises data pertaining to moving objects or moving obstructions which, as a result of a predicted path of the target vehicle, have a statistical likelihood of at least one of the following:
- coming into contact with the target vehicle, causing injury to a passenger of the target vehicle, causing injury to a bystander, or causing injury to a passenger of another vehicle.
