CAM-34

Unsignposted roadworks

Roadworks are taking up the pavement and the parking lane: fencing, pallets, pipes and a skip full of rubble. The sign that should warn of the narrowing is turned away and cannot be seen from the road.

The rule

You decide once. IRIS applies it always.

site fencing takes up the pavement or a lane

And alsono sign is visible at the entrance to the stretch

Then

alert the highways inspector
check the occupation permit
log the start date and the area occupied

The instruction that set it up«Tell me if roadworks take over the street without the signage in place, and what exactly they occupy.»

What changes

What changes for whoever runs the city

The sign that should announce the narrowing is turned to face the wall. The father pushing a pram finds the pavement closed and has to step into the road, between cars. Today the highways inspector finds out about that site when a complaint comes in, or when something has already happened. With IRIS he sees the hoarding from day one, how much pavement and how much lane it takes and whether the signage is in place, and he can cross that with the permit register. He knows which works are open in the street, not only which are open on paper.

What people usually ask

Can IRIS tell whether roadworks have a permit?

IRIS does not open the permit file on its own, but it does make the comparison with what is in the street possible. It detects the fencing, the date it appears and the area it takes up, and those figures are cross-checked with the council's permit register through the API. When there are works in the street and no open permit for that stretch, the alert fires. What IRIS adds is the part nobody looks at today: what is actually on the ground.

Does IRIS detect missing signage, or only that works are there?

IRIS detects both things — the works and the missing signage — and each is configured separately. On one side it recognises the fencing and how much it takes up; on the other it checks whether the signage that should be at that spot is visible in the image. A sign turned around or lying on the ground does not read as a sign, and that is precisely what you want to know. Anything outside the frame cannot be checked from there.

Can IRIS show whether works take up more space than they are allowed?

IRIS measures what the works take up on the image: how much pavement and how much lane, and from what day. Comparing that with what was authorised requires the permit data, which the council holds. Put the two together and the gap between what the paperwork says and what is on the street shows up straight away — the part almost nobody looks at today.
