Tram traffic lights on the ground

lights

A new form of traffic lights has been invented to prevent people focussed on their smart phones from hurting themselves and others. In the German city of Ausburg, red LED traffic lights have been embedded into the pavement at two tram stops by Stadtwerke Augsburg, to provide warning to those who forget to look up at the traditional eye-level lights.
