Abstract
The present disclosure is related to Intelligent Transport Systems (ITS), and in particular, to Vulnerable Road User (VRU) basic services (VBS) of a VRU ITS Station (ITS-S). Different arrangements and configurations of the VBS within the facilities layer of an ITS-S are described. Also described are different rules and/or conditions for VRU Awareness Message (VAM) formats, VAM generation and coding, and VAM dissemination.
Claims29
An apparatus in an originating Intelligent Transportation System Station (ITS-S), the apparatus comprising:
- memory circuitry to store instructions of a Vulnerable Road User (VRU) Basic Service (VBS) facility;
- and
- processor circuitry connected to the memory circuitry, wherein the processor circuitry is to operate the VBS to reduce VRU Awareness Message (VAM) overhead by:
- detect a VAM generation event,
- generate a VAM in response to detecting the VAM generation event,
- cause the generated VAM to be transmitted or broadcasted;
- and
- skip generation or transmission of a consecutive VAM when a set of VAM mitigation techniques is met.
One or more non-transitory computer readable media comprising instructions of a Vulnerable Road User (VRU) Basic Service (VBS) facility, wherein execution of the instructions by one or more processors of a non-Vulnerable Road User (VRU) Intelligent Transportation System Station (ITS-S) is to cause the non-VRU ITS-S to:
- detect at least one VRU from which the non-VRU ITS-S has not received any VRU Awareness Messages (VAMs) for at least a VAM transmission duration;
- generate a VAM in response to the detection of the at least one VRU;
- cause transmission of the generated VAM;
- and
- skip generation or transmission of a consecutive VAM when a set of VAM mitigation techniques is met to reduce VAM overhead.
A method of operating a Vulnerable Road User (VRU) Basic Service (VBS) facility of a non-Vulnerable Road User (VRU) Intelligent Transportation System Station (ITS-S), the method comprising:
- determining a set of VRUs or VRU clusters for reporting a VRU Awareness Message (VAM);
- generating the VAM to include a VAM extension container, the VAM extension container to include a first container and a second container, wherein the first container indicates a total individual VRUs in the set of VRUs and the second container indicates a total VRU clusters reported;
- causing transmission of the generated VAM;
- and
- skipping generation or transmission of a consecutive VAM when a set of VAM mitigation techniques is met to reduce VAM overhead.
