The equipment shown opposite was in service in Caen in the early 1970s: boulevard Dunois and from rue de Bayeux to rue St Gabriel.
They were replaced after a dozen years of service by Thomson CSF equipment in the early 1980s.
They are now kept within the management of the maintenance and operation of the public space of the urban community of Caen La Mer.

Electromechanical zone coordinator of American design from the manufacturer LFE dating from the 1970s.
It received the information transmitted by the TM24 module in order to coordinate several crossroads. Both needle gauges in part indicated the measured traffic volume.

Installations Balisage et Régulation (IBR), was a reseller of American equipment under Westinghouse license and Laboratory For Electronics (LFE) adapted for France, from the 1960s and 1970s. These were traffic lights but also electromechanical intersection controllers then with static electronics.
These materials were not very common, copies were installed in Caen, St Etienne, Trappes as well as in Seine Saint Denis (Le Blanc Mesnil, Tremblay in France, Sevran).
IBR was bought at the end of the 1970s by the Company for Studies and Realizations of Industrial Cybernetics (CERCI). In 1978, IBR-Cerci presented a prototype of a microprocessor controller for the city of Paris which was not retained.
