A phone call rings out to the “César” security PC on the A65, in Mont-de-Marsan. Bahija Cheddad, operator, picks up. On the other end of the line, a woman explains that her right rear tire has just flattened. She is currently on the emergency lane, waiting for a tow truck.

It’s the start of a race against time to avoid another accident. Immediately, Bahija Cheddad recalls the first actions to take. “Please bring your yellow vest and place yourself behind the guardrail. »

At his side, Stéphane Riaud, also an operator, tries to identify the vehicle using 16 surveillance cameras distributed in strategic locations on this 150-kilometer highway which extends from Langon (Gironde) to Pau (Pyrénées-Atlantiques). ). At the same time, a patrol sets out to secure the perimeter and guarantee “the fluidity of traffic”.

“We must be able to intervene within forty minutes,” says Sylvestre Gallice, technical director of A’liénor, the concession company for the Autoroute de Gascogne.


The operation of the motorway call terminals is checked every 15 days.

20,000 requests

This type of event – ​​called security assistance – PC operators must manage around ten per day on average. The majority of interventions consist of toll assistance (around 60 daily). “Hello, I can’t get my ticket,” exclaims a motorist. Stéphane comes to his rescue. After a few questions, the motorist can continue their journey.

In addition to an irregular working rhythm (operators work in 3-8 shifts), it is also necessary for them to master the basics of foreign languages.


The director of A’lienor plans to use data and IT to strengthen the security of patrol officers.

“The PC is the nerve center of the highway. This is where all the information arrives and leaves,” continues Sylvestre Gallice. Each year, the PC is called upon 20,000 times, 150 accidents must be managed and 1,600 repair interventions are carried out.

Data and AI

To best anticipate busy periods – namely summer holidays and winter holidays – the PC benefits from privileged links with Météo-France to have real-time weather forecasts, “respond to security” motorists and “being able to intervene” in the best conditions.

“You have to be ready at all times,” explains Alexandre Claude, director of the A’liénor company since 1er January 2024. During these periods, patrols are reinforced to be present “as quickly as possible with customers”.

Normally, there is relatively little traffic on this highway: 8,000 cars use it every day. And 22 patrol officers are on watch 24 hours a day to guarantee everyone’s safety. In the coming years, their work could be made easier thanks to “data, IT and artificial intelligence”. “Thanks to this, the objective is to predict areas with a potential risk of accident or traffic jam. »

Another possibility is the possibility of putting cameras on the back of patrol vehicles. “When the agent is on intervention, this camera will analyze the trajectory of the vehicles and can warn them using a connected object which emits a vibration at the level of the foot. »

In 2022, 169 accidents were recorded across the entire national motorway network. Figures that have continued to grow for several years.
