Whether by bike, on foot, on a scooter, or by car: sharing the road depends heavily on traffic lights. Within the Grenoble Metropolitan Area, traffic lights are controlled from a single location: the traffic control center. This large room is equipped with 24 screens that monitor the proper functioning of more than 500 traffic lights throughout the area, from the Grenoble Alpes Métropole Mobility Agency. How are they set? Are some longer than others? Come discover this facility, which is rarely open to the public. 

A copy of the participants' identification must be sent to the organizer at the time of registration.
