You can make sense of this if you have to, but who would?

The big failure is this kind of signage is supposed to take virtually zero time to read.

The designer hung on to their clock metaphor into the land of ridiculousness.

Clock Faces are habitually read in one kind of way, trying to overlay it with another order of info is only going to get you in trouble.

If they used a vertical segmented list like a day planner, we would get times of operation and people volume in one place and we wouldn't have to reverse engineer the clock/pie chart mashup.

Though saying that I want to make an even more obtuse clock/pie chart mashup :)
