Green dots applied as new street signals in Berlin, Germany

A pedestrian with a bicycle walks across a green dotted street area in Bergmann Street of Kreuzberg, southern Berlin, Germany, on May 7, 2019. The green dots, part of new street signals in Berlin, are applied as a trial at a part of Bergmann Street with a speed limit of 20km/h, aiming to induce vehicles to drive with restricted speed.
