There are also steps ... and steps drawn as areas ... some as trapezoids
.. some as rectangles with a different number of steps from one side to
And pavement areas under buildings, train and road ways ... inside
tunnels, on covered bridges .. lots of variations.
Some roads have a fence on the dividing strip between opposing traffic
specifically to stop pedestrians from crossing the roadway.
