Hi,
The controller classes have a protected method called SimulateAdvance. It documentation says
"Advance the controller and return the new position. Contrary to <see cref="Advance"/>, this method will not do any side effect operations, like updating some internal state, or triggering events"
You can use this method instead of having a trigger in front of your object, it will yield better results.
You can expose publicly the method in your own controller class (inheriting from SplineController for example) and then have a crowd manager that will simulate the advance of all the controllers, then detect collisions and modify the properties of the relevant controllers.
If you can't find a simple logic that benefits from your game scene constraints, give a try to this method:
http://gamma.cs.unc.edu/ORCA/publications/ORCA.pdf
Unlike what the paper states, your objects can't move freely, so you will need to modify their solution to fit your constraints.
PS: I never worked with collision avoidance, neither have I implemented the above paper, so I have zero experience on this field. It's just that years ago I attended to a talk of a Crytek employee presenting this method, or a very similar one, which they implemented in Crysis 2
