road layout is: footway, roadside parking, cycle lane, 2 drive lanes, bus lane, barrier. And in opposite order same on other side of barrier. See mapillary or aerial images.

Pedestrians sometimes cross the street (which is legal if and only if they use one of the gaps in the barrier and current traffic allows it. See §25 3,4 of German road code), but it's discouraged because they often have to wait on the bus lane.
