restrict AGVS to main roads

My AGVs are outsmarting me.

They should follow the aqua path: drive from the top horizontal to the left, then drop (x), then leave using the bottom horizontal to the right.

It is actually driving in using the top horizontal, dropping (x), then doing a backflip into a drop location without dropping (:| ) , then driving again to the left.

Can I restrict driving the drop lanes only for pick / drop?

As I remember it is a result of shortest distance that leads to this result. BUT you can apply cost labels to path sections that will evaluated in conjunction with path finding algorithm. If your main path length costs less than any shorter distanced short cut, AGV will be kept on main path.

Jörg's comment is one possible answer: Multiply the path cost of the sidings by a large value so the task executers will only use if absolutely necessary. (Route costs are set in the 'General' tab of the AGV Network Properties)

Another option would be to use conditional rules: Only allow the task executers to use the sidings under certain conditions that represent them needing to unload/load at that location. (Path Rules are created in the corresponding tab of the Network properties and then assign in the properties of each path)

The attached model demonstrates both approaches. The green path has a cost multiplier of 500, so the AGVs only use it to unload at the green queue. They are only allowed to travel on the red path if they are transporting an item with Type 1 (need to unload at red queue). When transporting items to the blue queue, they will take the long way.
