How to check for any incoming traffic on highway while merging to highway?

[ FlexSim 19.2.4 ]

traffic sample.fsmI have a small sample model where I have 5 aisle from where operators want to merge on a common highway. On arriving at the last network node of the aisle (which is the network node that connects the aisle to highway node in front of it), I want operators to stop and check for any ongoing highway traffic before they merge to highway (the highway section to the left and right of the aisle should be clear in order to merge safely). Once that highway section is clear, the operator can exit the aisle and merge to highway. I tried to do this using traffic control but it doesn't seem to work the way I want it. Maybe untimed traffic control mode can help? Another way could be using on arrival triggers of aisle end node.
(The reason why traffic control method failed for me is because in my actual model, I have way more aisles and operators and at some point, I run into deadlock situation between two operators controlled by traffic controller)

Hi @Kashif A,

I apologize no one has looked at this sooner. The model you've attached has a broken link. Would you be able to upload it again in a comment? This is a problem with the Answers Hub forum, not with your model.

Hi @Kashif A,

You have the right idea, you just need to restrict your "Maximum Number in Area". You currently have it set to 1000. If you set it to 1, it looks like this:
