That is, rather than positioning a queue as some extra entity in the code, it\u2019s also possible to think of a queue as an emergent behaviour stemming from how the agents in a system behave. You really only need a couple of \u201crules\u201d to establish queuing \u2013 the idea that people stop if they run into the back of someone else, the idea that everyone is moving along in a line with each other, and the idea that the front person gets stopped by some external force (such as a ticket barrier, say).
