How to build a traffic light logic ?

I am trying to build a traffic light logic at the intersection of my model.

However, everytime the traffic controller goes green, only one vehicle is allowed to go.

I need some help to fix this so every following vehicle can also leave until the Traffic Control1 goes red.

Attached is the model: network-nodes-and-trafic-control-update.fsm

Software Version:

FlexSim 23.1.1

traffic light logic

network-nodes-and-trafic-control-update.fsm (3.1 MiB)

Do you have a model that runs?

We encourage students to research and try and solve the problems themselves and if they get stuck offer guidance.

Here's the documentation for the Traffic Control.

Here's a previous post and example.

You should use the entryRequest trigger to return the correct value for the color state to "allow" entry or "queue". Add that either directly or in a process flow with a return value override:

I would also increase the max travelers from zero - that just seems odd.
