A way to disable civilian traffic in certain areas (like around a road base)

[Inf]

Roadside FARPS / roadbases are fairly useless if civilian traffic will pay no attention and crash into your aircraft.
I'd love if this was handled somehow - short of completely disabling traffic for the whole map.

Something like a Trigger Zone you could place which will either hide (or at very least remove collisions from) civvy traffic while they're in it would be fine.

A roadblock placeable static object that despawned or hid the traffic would be OK as well.
