Passengers in the braking zone
A train is coming into the station and is still braking. In the first metres of the platform there are passengers past the safety line, right up against the edge.

What IRIS understands
What it recognises in this scene
- train coming in
- safety line
- waiting passengers
The rule
You decide once. IRIS applies it always.
If
there are people past the safety line in the stretch where the train is still braking
And alsoa train is coming into that platform
Then
- play the platform announcement on that platform, and only that one
- alert the platform staff if people are still past the line
- log the platform and the time, to learn which platform head it always happens at
The instruction that set it up«Tell me if people are past the yellow line at the head of the platform while a train is coming in.»
What changes
What changes for whoever runs the station
Everyone leans out a little to see if the train is coming, and at the head of the platform the train has not finished braking. The station supervisor cannot stand at that spot every six minutes, and a public-address warning that plays all day on every platform stops being heard within a week. With IRIS the announcement only plays when somebody really is past the line with a train coming in, so it means something again. And after a month that supervisor knows which head of which platform concentrates the problem — which is where the paint or the railing has to go.
What people usually ask
Can IRIS trigger the announcement on its own?
Yes, and it is one of the few actions worth automating, because a recorded message saying «please stand back from the line» harms nobody if it gets it wrong. The condition is that it plays rarely: if it plays constantly, people stop hearing it and the warning turns into background noise. Any action that moves a person or holds a train is still decided by someone at the station.
How does IRIS know where the braking zone is?
A person draws it on the camera's own picture on commissioning day: you mark the stretch of platform where the train is still braking and the safety line, and there it stays. Nothing has to be measured and no signage has to be touched: you draw over the image and check it against a real train. If the stopping point changes tomorrow, it is redrawn in a minute.
Does it also help decide whether platform screen doors are needed?
It helps you argue with numbers instead of impressions. After a few months you have a count of how often a day people go past the line, on which platform, at what time and with which service, and that count is what goes into the meeting where the investment is decided. The decision is still the station's; what changes is that it stops being made by eye.
A different case every time
Everything comes in. Only what matters gets through.
This sums up what IRIS does with one alert, from the moment it appears until it is closed. The real screen holds far more; this is the main thread.
- Four cameras at once
- Each understands its own view
- The numbers climb by themselves
Next step
When does a bad review get decided?
15 cases: 11 raise an alert when something happens and 4 only measure. You see each image as it is, and then with what IRIS understands on top.
Who is watching a whole quay at three in the morning?
14 cases: 13 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 cannot describe a line with a sentence.You have to draw it on the image.
Asking is for finding; counting is for measuring. That is why the number comes out the same every day, and why people counting is certified by the Centro Español de Metrología.
