You can avoid collision with each other by increasing the Node Spacing. This allows more space between nodes the A* creates to build its pathing, so the Transports don't come as close to each other.

@Joshua S So spacing between vehicles/operators etc. using A Star is defined solely by node spacing, not by the physical size of the transport (or flow item?)

@Craig DIckson correct.

@Joshua S Making the grid spacing larger works for the queuing, except that it makes the location less accurate. Even if I use a Travel to Location activity, the TE will often stop one or more nodes away, which in this case is in the middle of a travel aisle. Is there a way to force the TE to an exact grid location?
