Roundabout is selling a traffic-control system to cities that are tired of timing intersections with stale assumptions.

## What it does

Roundabout Technologies says its AI watches vehicles, bikes, buses, and pedestrians and changes signal timing in response. The [company site](https://www.roundabout.tech/) describes a live intersection dashboard, safety metrics, corridor coordination, and dynamic phase extensions.

The buyer is a city or transportation department. The product is not a consumer traffic app. It sits inside public infrastructure, which makes deployment, data ownership, safety, procurement, and public accountability part of the purchase.

| Fact | What the public source says |
| --- | --- |
| Buyer | Cities and public-works or transportation teams |
| Product | AI-powered signal control plus monitoring and safety views |
| Early deployment | San Anselmo’s Hub intersection is the public reference case |
