Pedestrians may walk in all directions at the same time
At intersections in Germany the directions of crossing traffic get normally one GREEN-signal after another. This is not very comfortable for pedestrians who have to pass two roads: the have to wait up to two times. At this intersection the pedestrians get GREEN for all directions at the same time and also for the diagonal path. Due to the then required longer green-time the waiting time may be increased for crossing a single arm.
