Variable message sign
A variable message sign above the carriageway is showing the word 'DANGER' with some of its LEDs burnt out: the letters in the middle have pieces missing and cannot be read from a car.

The rule
You decide once. IRIS applies it always.
If
the sign looks dark, incomplete or with letters that cannot be read
Then
- alert the maintenance manager with the photo of the sign
- open a fault report for the sign
- tell the control room that this message is not getting through
The instruction that set it up«Tell me if a sign looks broken, dark or with the message incomplete when seen from the road.»
What changes
What changes for whoever runs the road
Today nobody checks that a sign is actually showing what it was told to show. The control room sends the order, the sign replies that it has received it, and that is where the checking stops: whether the message can be read, and read in full, is only known when somebody drives past and looks at it. A sign with burnt-out LEDs keeps answering 'OK' while displaying a word nobody can read. IRIS looks at it from the outside, the way the driver looks at it, and tells the maintenance manager the same day it fails, not when a member of the public reports it. A sign is safety infrastructure: if it warns of a danger and cannot be read, it is worse than not having it, because back in the room they believe the warning has been given.
What people usually ask
Which sign faults does IRIS pick up?
Two, and they are the ones that matter. One: the sign is broken or dark — LEDs missing, the word coming out incomplete, or the panel black when it should be lit. Two: it is showing the wrong message, because it kept yesterday's or because it did not change when it was told to. The first can be seen just by looking at the sign; the second also needs to know what it was asked to display.
Can IRIS tell whether the sign is showing the wrong message?
Only if the system that drives the signs is connected. IRIS reads what is visible on the sign; to say that this text is not the right one, you have to be able to compare it with the order that was sent, and that requires a link to that system. Without it, IRIS still reports that the sign is broken, dark or unreadable, but not that it is showing something different from what was ordered. We would rather say this plainly than promise it and fall short.
Can a sign always be read, at night and against the light?
Not always, and it depends on the framing and the light. A sign with the sun straight ahead, or at night in heavy rain, can be unreadable for the camera just as it is hard for the driver. That is why we check camera by camera before promising anything: if the sign cannot be reliably read from that spot, the framing is changed or the sign is left out. What we do not do is accept a reading that does not hold up.
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.
- The rule gets built
- It goes to every camera
- Published, it watches alone
- And then it fires
Next step
What does a venue with twenty thousand people inside see?
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.
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.
And the best part
What happens outside the framedoes not exist for IRIS. No camera sees the whole world.
So the first thing we do is check what each camera covers and write it down: from here you can understand this, and not that. A dull hour that saves a lot of misunderstandings.
Tell us your problem and we will say whether IRIS understands it, or not yet.
We reply the same working day.
