The traffic

Although the first automobiles began to manufactured at the beginning of the 20th century, at that time it was still of a luxury means of transportation: many years still had to pass until that they became protagonists of urban life in the large cities. Its introduction was slow, but it aggravated a problem that required innovative solutions: traffic.

John Peake Knight

To regulate the passage of people and carriages, John Peake Knight had already invented in 1868 a first mechanical traffic light. But it was from 1912 onwards when the greater efforts to solve this problem from the United States: it was then when a new language was designed based on colored lights.

Pioneer in implementation

SICE, was a pioneer in the implementation of this new system in Spain: installed the first traffic lights in Madrid (1926) and Barcelona (1929). In the Homes, they were manually operated by traffic wardens, but soon regulators began to be employed, that turned the traffic lights on and off at intervals of time set in advance. In the 1940s and 1950s, SICE installed these simple equipment throughout the entire geography Spanish.

Urban traffic

However, the vehicle fleet I was growing very fast. Since Spain began the own manufacturing of passenger vehicles, around 1953, it became more necessary than ever to offer citizens an agile solution to organize traffic regulation.

The zone center

It was in 1958 when the most innovative system of the time was installed: “the zone exchange.”

The function of the zone control unit was to synchronize the phases and traffic light cycles at different intersections guaranteeing safety of users and comfortable and fluid circulation of vehicles.

Designed by the engineer Gabriel Ferraté, the first power plant allowed the synchronized lighting of the traffic lights at 12 intersections in the Urgell street, in Barcelona.

The evolution of traffic control systems (traffic management mobility) in cities has not stopped to this day evolving from electromechanical systems to the latest connected vehicle technologies and 5G communications.
