For the life of me, I can't figure out what purpose there would be for short segments of sidewalk, with a yellow pad right in the middle, only on the corners of each intersection. This whole suburban development in Crozet is spotted with these things. Do they make pedestrians safer? Do they add some aesthetic value to the street? Doubt it. My guess is that the literal interpretation of the zoning code only requires the developers to put sidewalks on the corners. So that's what they did.
