It's a good design. Will the PR be merged in the roadmap?
Also, if I understand correctly, the router in the v2x component will be implemented in the future, right?

Thank you. Since it has been discussed several times, I think it would be a good idea to merge and try it out.
@mitsudome-r @yukkysaito What do you think? Would it be better to separate the package so that it can be seen that it is a prototype message because it has not been sufficiently tested?

Also, if I understand correctly, the router in the v2x component will be implemented in the future, right?

Yes, the v2x component does not exist yet, so we need to create a new one.

Once the maintainer information is updated, the PR looks good to me.

Maybe we can change the interface name to something like:

• Lock Road Interface
• Acquire Road Interface
• Request to Pass Interface

[isamu-takagi]

Maybe we can change the interface name to something like:

@mitsudome-r @yukkysaito Similar messages are "Signal Request Message" and "Signal Status Message" called in ITS standards. So what about the following names?

• RoadLockRequest.msg / RoadLockStatus.msg
• AcquireRoadRequest.msg / AcquireRoadStatus.msg
• RightOfWayRequest.msg / RightOfWayStatus.msg
• PassPermitRequest.msg / PassPermitStatus.msg

I don't mind with virtual gate messages for now.
