The Ulys Tunnel Operations Service - Vinci S.A. bets on smarter French tolls

The Ulys Tunnel Operations Service from Vinci Autoroutes hums in the background while drivers grip the wheel and squint into the sodium-yellow glow of French motorway tunnels, trusting that someone is watching every camera feed and sensor alert.

Digital control in Vinci tunnels

At the heart of the Ulys Tunnel Operations Service sits a series of regional control centers, where operators track live video streams, traffic density and environmental sensors across multiple motorway tunnels in the Vinci Autoroutes network.

On a typical night shift, a controller like Stéphane Delebarre leans forward over an array of screens, watching vehicles slice through the dim light while automatic incident detection software flags slowdowns or stopped cars in real time.

How Ulys monitors tunnels

Vinci Autoroutes describes Ulys as its digital ecosystem for motorway services, integrating apps, roadside systems and control centers to make journeys smoother and safer across more than 4,400 kilometers of French motorways.

Within that ecosystem, the Tunnel Operations Service combines CCTV networks, traffic counters, ventilation controls and fire detection sensors, feeding data into supervision software that can trigger alarms and predefined emergency scenarios.

Incident response and safety workflows

When an incident is detected, the Ulys Tunnel Operations Service guides the controller through a scripted response: slow traffic with dynamic speed signs, close lanes or portals remotely, and dispatch patrol teams or emergency services if needed.

For drivers, that orchestration translates into rapid changes on overhead LED displays, flashing lane crosses and sometimes the abrupt smell of hot brakes as vehicles funnel into a single open lane under close surveillance.

Role in Vinci’s toll business

Vinci Autoroutes operates long-term motorway concession contracts in France, where toll revenue depends on keeping traffic flowing and tunnels safe enough for regulators to maintain approvals and users to keep paying.

Chief executive Pierre Coppey has repeatedly stressed that operational safety and continuity in critical infrastructure like tunnels are central to the division’s economic performance, underpinning the steady cash flows that attract infrastructure investors to the Vinci S.A. share.
