# How can a city, county or road team use computer vision to keep an inventory of road signs and spot ones that need work?

A camera on a work truck records the road as crews drive their usual routes, and the model finds each sign, reads its type, and marks ones that look faded, bent, leaning, blocked by trees, covered in graffiti or missing from where the inventory says they should be. Each find is saved with the photo, GPS spot and date, so the team keeps one up-to-date list and can plan fixes by priority. A traffic engineer or sign crew lead decides every repair, and the usual night checks, standards and records stay in place.

## What this means in practice

- A camera on a work truck or pickup records the road as crews drive their usual routes, ideally at the same speed and time of day each pass.
- The model is trained on the owner own roads and sign types. It finds each sign, reads what type it is, and marks ones that look faded, peeling, bent, leaning, twisted, blocked by trees or brush, covered in stickers or graffiti, or missing from where the inventory says they should be.
- Each find is saved with the photo, the GPS spot, the sign type and the date, so the team keeps one up-to-date list and can compare it with the last pass to see what changed.
- A traffic engineer or sign crew lead reviews every mark and decides what gets fixed, replaced, trimmed or just watched. The cameras point at the road, and any people or plates caught in view are blurred.
- Start with one district or route, compare the camera list with what the crews know for a few weeks, and keep the existing night visibility checks, sign standards, work orders and records in place.

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
