Description

See traffic light on Wikipedia

Traffic signals are automated mechanisms for instructing road users to wait or to proceed at an intersection or section of a road.

traffic_signals:vibration=*	Whether there are vibrating signals for visually impaired and deaf people

Traffic signals at crossings for pedestrians

For pedestrians, the Key:crossing tag is used instead of highway=traffic_signals. The additional tags traffic_signals:sound=* and several similar are especially useful and should better be used on the pedestrian crossings. Please use them on highway=traffic_signals, if the pedestrian crossings are not (yet) tagged separately!

Notes

As of now, there is no well established convention.

For simple intersection of 4 sections, the intersection node is simply tagged. But when it comes to some more complicated intersections, many parameters come into account. See the intersection below

The horizontal ways are actually one large way. The problem is how to make sure the "traffic_signals" is applied to all "ways". To make sure it applies to the two horizontal ways, we should add the tag to both nodes intersecting with the vertical way. But that'd make two separate traffic signals, and there is physically ONE set of traffic signals.

Please discuss this on the discussion page or on Proposed features/Set of Traffic Signals.
