CAM-83
Platform over capacity
The platform is packed from wall to wall and there is no clear space left beside the edge. On the exit stairs a queue is backed up and not moving.

What IRIS understands
What it recognises in this scene
- packed platform
- platform edge
- blocked exit
The rule
You decide once. IRIS applies it always.
If
the density of people on the platform goes past the limit the station has set
Duringmore than two minutes in a row, so a single arriving train does not set it off
Then
- alert the station supervisor with the platform and the point where it is tightest
- alert the control room so it can weigh closing entrances or opening another exit
- log the time and how long it lasted, for the day's report
The instruction that set it up«Tell me when a platform fills up so much that people can no longer step back from the edge.»
What changes
What changes for whoever runs the station
The risk of a packed platform is not discomfort: it is the shove. Once there is no space left, the people arriving push forward and those in the front row have nowhere to step back to. The station supervisor knows this, but from his office he cannot see four platforms at once and today he finds out when he walks down to look. With IRIS he gets the alert while the platform is filling up, with the exact point where it is tightest, and there is still time to close an entrance, open the other exit or ask for an extra train.
What people usually ask
Does IRIS count faces to know how many people there are?
No. It counts bodies, not faces: for IRIS each person is a shape taking up room on the platform, exactly like a suitcase or a trolley. It recognises nobody, compares against no database and stores no record of who went through. What it gives back is how many people there are and where they bunch up — the only thing needed by whoever has to decide whether to close an entrance.
Our platform is packed every morning at eight. Won't it be alerting non-stop?
If it were badly set up, yes — and somebody would switch it off within two days. That is why the limit is not a universal number: the station sets it per platform and per time band. The usual approach is to give the rush hour a higher limit and only alert above it, or when the density stays high after a train has left, which is the sign that something is not moving.
Does IRIS warn before the platform fills up?
IRIS does not predict: it sees what is happening. What it does do is raise the alert before it becomes a problem, because it watches the density as it climbs and not once it is already over the top. Between the moment a platform gets uncomfortable and the moment it starts pushing there are a few minutes, and those minutes are exactly what whoever has to decide gains.
The real interface, step by step
You set the rule once. IRIS applies it every time.
You will see a summary of the interface, played step by step and hands-free. Each round starts with another case. The complete tool does not fit in a demo.

Next step
Who is watching when the load swings over somebody?
11 cases: 9 raise an alert when something happens and 2 only measure. You see each image as it is, and then with what IRIS understands on top.
Who is watching the yard screen when the fight starts?
17 cases: 16 raise an alert when something happens and 1 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
You can ask which van came in yesterday.Who was inside is not a question you ask here.
IRIS searches for things and situations, not people: it identifies nobody and recognises no faces. You write what you are looking for and it returns the matching minutes.
Tell us your problem and we will say whether IRIS understands it, or not yet.
We reply the same working day.
