It's interesting that the effects are so complex and nuanced. I also wonder - they didn't specify - just how reflective these surfaces need to be, and how "bright" they are to look at. I could see glare being a potential safety hazard if the surface is reflective enough, but I'm assuming that any surface rough enough to make good pavement won't be _too_ bad to look at.

The discovery that light colors absorb less heat isn’t remarkable. I would be embarrassed to see this if I were an MIG alumnus. Statements about replacing all pavement in a metropolitan area (that doesn’t even patch its potholes) are so out of touch that they discredit the whole article. Just replace all that asphalt with concrete filled with, I guess, prismatic beads which would be like staring at the sun? Brilliant! Oh, or use “lighter colored aggregates”? Right. We I never thought to just ask the local geology to rearrange itself a bit so my local quarries can produce a different color product. I’ll give it a go! Several here have made the much more obvious observation: just use plants.
