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.
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.
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.
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.
