Random information on the term “Traffic signals”:
Ampelmännchen (German: [ˈampl̩ˌmɛnçən] ( listen); literally little traffic light men, diminutive of Ampelmann [ampl̩ˈman]) is the symbol shown on pedestrian signals in Germany. Prior to German reunification in 1989, the two German states had different forms for the Ampelmännchen, with a generic human figure in West Germany, and a generally “male” figure wearing a hat in the East.
The Ampelmännchen is a beloved symbol in Eastern Germany, “enjoy[ing] the privileged status of being one of the few features of communist East Germany to have survived the end of the Iron Curtain with his popularity unscathed.” After the fall of the Berlin Wall, the Ampelmännchen acquired cult status and became a popular souvenir item in the tourism business.
The first traffic lights at pedestrian crossings were erected in the 1950s, and many countries developed different designs (which were eventually standardised). At that time, traffic lights were the same for cars, bicycles and pedestrians. The East Berlin Ampelmännchen was created in 1961 by traffic psychologist Karl Peglau (1927–2009) as part of a proposal for a new traffic lights layout. Peglau criticised the fact that the standard colours of the traffic lights (red, yellow, green) did not provide for road users who were unable to differentiate between colours (10 percent of the total population); and that the lights themselves were too small and too weak when competing against luminous advertising and sunlight. Peglau proposed retaining the three colours while introducing intuitive shapes for each coloured light. This idea received strong support from many sides, but Peglau’s plans were doomed by the high costs involved in replacing existing traffic light infrastructure.
