An embedded flashing-light system, or an in-pavement flashing-light system, is a traffic safety device installed at pedestrian crossings or intersections to enhance driver awareness of pedestrians or traffic signals. These systems typically consist of LED lights embedded within the road surface, positioned to face oncoming traffic or pedestrians.
The first traffic lights at pedestrian crossings were erected in the 1950s, and many countries developed different designs (which were eventually standardised). [3] At that time, traffic lights were the same for cars, bicycles and pedestrians. [4] The East Berlin Ampelmännchen was created in 1961 by traffic psychologist Karl Peglau (1927 ...
At signalized intersections, crosswalks may have pedestrian signals which display symbols to mandate when pedestrians may cross the street. State road rules in the United States usually require a driver to yield the right of way to a pedestrian crossing a road when the pedestrian crosses at a marked crosswalk or an unmarked crosswalk. [2]
The term "pedestrian crossing" is also used in the Vienna and Geneva Conventions, both of which pertain to road signs and road traffic. Marked pedestrian crossings are often found at intersections, but may also be at other points on busy roads that would otherwise be too unsafe to cross without assistance due to vehicle numbers, speed or road ...
Xiaolüren, a sign on traffic signals for pedestrians, was created in 1961 by traffic psychologist Karl Peglau (1927–2009) as part of a proposal for a new traffic lights layout in East Berlin, Germany. The sign is generally for pedestrian road-crossings. The frontal-facing red man denotes "stop", while the animated side-facing green man in ...

The vehicular signal head has three sections, consisting of two horizontally arranged circular red sections over a single circular yellow section that is centered between the red lights. The MUTCD requires at least two HAWK signal faces facing each vehicular approach to the crossing. Normal pedestrian signal heads control pedestrian traffic.
In New Zealand, where they drive on the left, when a road is given a green light from an all direction stop, a red arrow can continue to display to turning traffic, holding traffic back while the pedestrian crossing on the side road is given a green signal (for left turns) or while oncoming traffic goes straight ahead and there is no permissive right turn allowed (for right turns).
