Default Batch transport using network

Hi,
My purpose is so simply. Transport football fans from one place to other, using 3 (or more) buses. I’ve started to build network with bus stops (buffers) and dispatcher. I would like bus fully use its capacity (30 people) – it’s obvious.
Problems:
1. Sometimes buses carry only 1 person or a few, despite in buffer there are much more.
2. Buses wait to the same stop, despite other buffer are free (nodes are opened) and there is a proper quantity of people in buffers.
3. Sometimes buses don’t unload people near BufferOut.
Thanks in advance for your help.

I had to modify a bit your code to make it work.

Please see the attached model.

I'm playing a bit with the rules in the model, but I hope this can show "potential ideas" to control the logic.

What I've deleted:
1)The command to openinput (of the transporters) when the queues 2 and 3 exceeded a certain quantity.
2) The maximum stay time in the Queue I've also modified (otherwise the objects will be released)
3) I've changed the graphics of the transporters (but these can be returned to your buses)

What I've added:
4) I start with the "fans" buffer. In order to send the fans into the same queue, I am playing with labels to send them in a "bunch" of 30, to a round robin port.
5) On Exit from the "bus stop" I'm opening and closing input ports of the next bus, so it can gather some work
6) I've re-ranked the output port connections on the dispatcher.

Good luck
