The cellular view of a queue
Sober, stationary strangers for hours. The most connective room here, by a distance.
The conditions of this room
Four numbers decide what a crowd does: how tightly it is packed, how loud it is, how fast alcohol arrives, and how much attention is available for the people beside you. Everything below is either a published figure or derived from one.
What those conditions do to people
A queue has none of the machinery a venue uses to make people meet. No alcohol, no music, no lighting, nobody employed to make it happen. It has one property instead: the person next to you is not going anywhere, and neither are you, for hours.
That turns out to beat everything else. In the model a queue produces the largest connected component of any room here — 634 of 1,200 people end up in a single network after four hours, against 213 in a nightclub and seven at a street crossing. It does this completely sober.
Two conditions do the work. The room is quiet, so speech carries the full 3.6 metres of Hall's social zone rather than the 75 centimetres a club allows. And almost nobody is in transit, so attention is available. Density is a modest 1.5 people per square metre — a queue does not win on packing. It wins because nothing is competing for anyone's attention.
What the model produces
Measured output from a standard run: 1,200 people, 4 hours of venue time, fixed seed, no parameter overrides. Every room on this site is run under identical conditions, so these figures are a like-for-like comparison rather than a set of individually flattering runs.
The crowd is a simulation and is presented as one. What is not invented are its constants: walking speed against density, the proxemic zones, the collapse of speech range with noise, the Widmark blood-alcohol curve and the conversational group limit all come from published work, cited above and listed in full in the engine.

Every gathering below is modelled as this kind of room. Attendance figures are published numbers for the period stated.
Questions
Why do strangers bond in queues?
Two conditions combine: the environment is quiet enough that speech carries several metres, and nobody is going anywhere, so attention is available. In this model those two factors matter far more than density or alcohol.
How big was the lying-in-state queue?
Around 250,000 people passed through it over four and a half days in September 2022, at times waiting more than 12 hours.
Is a queue really more social than a nightclub?
In lasting connections, yes. A queue produces a largest connected group roughly three times bigger than a nightclub's over the same four hours, with no alcohol at all — although a nightclub still generates more raw encounters per hour.
How this is modelled
Each person is one cell with a position, a body mass, a Widmark distribution ratio, an openness trait and a reserve of energy. They walk at the speed the local density allows, drink at the rate the room serves, and when two of them stay within speech range long enough, a bond forms. Most bonds are nothing.
What separates an encounter that creates something from one that does not is whether it bridges two groups that were not previously connected. A tie inside an existing group mostly restates what that group already knows; a tie across a gap carries information neither side had. That distinction is Granovetter's, and it is the mechanic the whole model turns on.
One parameter has no citation and should be read as an assumption: attention, the share of a person available to whoever is beside them rather than to a stage, a road or a rite. It is the variable that separates a street crossing from a dancefloor at similar density, and it is the one this model asserts rather than borrows.
