29 spreaders that can be mobilized when needed
A command post based in Evry-Courcouronnes makes it possible to centralize the various information, to know in real time the traffic conditions, the meteorological data and the treatments carried out in order to coordinate the actions in the field as well as possible.
The agents are then responsible for salting and/or clearing the roadway according to pre-defined circuits.
