# How can a city, road agency or parking lot owner use computer vision to find worn road and lot markings?

A camera on a vehicle that already drives the routes takes photos of the pavement as it goes. A model trained on the owner own images marks lane lines, crosswalks, stop bars, arrows and parking stalls that look faded, broken or missing, and tags each one with a place and a photo. Comparing one pass with the next shows which stretches wear fastest, which helps plan repainting by priority instead of by calendar. Blur any person or plate before photos are stored. A crew lead reviews the flags and decides what gets repainted and when. The model does not replace official inspections or the rules for marking design, which stay in place, and people make every work order call.

## What this means in practice

- Start with one route or a few busy lots.
- Label photos from your own roads for faded, broken and missing markings.
- Blur people and plates before photos are stored.
- Send each flag to the crew lead with a place and a photo.
- Compare passes to plan repainting by wear, not by calendar.

## 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.
