Network node dynamicly allow acces for 1 specific operator only

Hello,

I have the following problem,

On my network (controlled by traffic control)
I allow a nr of users on a controlled path.

When one specific type of operator enteres the networkpath, the path should be closed for all other operators untill he leaves,

I tried using the following code on the onentry trigger of the traffic control

/**Custom Code*/
treenode current = ownerobject(c);
treenode traveler = parnode(1);
//is this one connected to the replenishment trucks
if(tonum(inobject(traveler,1)) == tonum(DispatcherSpareReplenishmentRucks))
{
//treenode variable = getvarnode("maxactive",current);
setvarnum(current,"maxactive",1);
}

but the traffic control doesn't get reset.

Secondly would it be possible to close the path after the operator leaves the path, and then after open it but only for the same operator that just left?

It would simulate the following:
1 a repl truck enters an aisl
2 the aisle is now closed for all other operators
3 the truck will leave and enter the aisle multiple times but untill all replenishment is done the aisle should remain closed to all operators
4 after the truck finishes replenishment, it will open the aisle again to the other operators

Thanks for any help and or tips

Koen,

you can use opennodeedge() and closenodeedge() to open and close single edges between network nodes. I do not know how to easily allow only a specific TE to move forward into the aisle.
Have you thought about using a different network for operators and trucks to replenish? in that case you could control nodeedges of one network based on the status of the other one.

Good luck

Hello Koen,

we had a similar question in the past. Then only a classtype was allowed to enter a controlled path. You find the approach here.

Koen,

I felt your case was practical enough to deserve an example model.

The TrafficControl in the attached model will allow only one Replen operator in the area, otherwise "Maximum Number in Area" Pickers are allowed. Requests are handled FIFO. I added a label to the TrafficControl object, and modified the OnEntryRequest and OnExit triggers.

Forgive the fact that the pickers aren't actually picking.
