Problem with truck lines with network nodes

Hi,

I am working on a distribution center model and I have an issue with the truck lines. When they stop on the network node for the check in, the next truck on the line does not stops correctly, it goes on top of the first truck even tough the max travelers on the node is 1. (red box1)

Is there an easy way to fix this? Here is the model. Nodes Truck lines model.fsm

I know this can be done with AGV networks but for other reasons we prefer to use nodes on this project.


Thanks!

I'm not sure whether this happens because:

a) a traveler at a network node is not taken into account for the "non-passing" functionality, or

b) a delayed traveler is not taken into account.

Anyway, I can only offer a workaround. If you add another network node in front of the one where the trucks are waiting and connect both to a traffic control, the next truck will wait at the node in front, rather than travel up to "delay" node.

I found a easy solution by using the "Do not Travel offsets and block space on networks" on the truck flow item bin.
