.... are elegant in their simplicity.
Do you think this design qualifies?
In structural efficiency ~ yes.
In practical usage ~ perhaps not.
Consider a time of heavy pedestrian traffic.
Say, class change on a university campus,
or the end of the work day.
Lots of people walking up and down
Enter a person on crutches
or in a wheelchair.
His/her progress would be
across the flow of pedestrian traffic
all the way.
Relying upon the milk of human kindness
can be a chancy proposition
for those with disabilities.
Or what if heavy snowfall or freezing rain
made the steps treacherous,
and the ramp even more so?
Heat from below would help.
What do you think?
