When I studied Urban Planning in 1972, my transportation professor that the "new thinking" was to separate pedestrians and vehicles at intersections to minimize conflicts.

1972's "new thinking" is today's 40-year-old thinking. That was the era of adapting formerly walkable downtowns to function on the scale of the automobile.

I finally saw that thinking in action on the strip in Las Vegas in 2010. It works quite well. It is a slight nuisance for the pedestrian, but it would be much worse to cross at street level crossing twelve lanes of traffic. Congestion would be much worse and there would be many pedestrian car accidents. I can't even imagine that area without the overpasses. You should be able to see what it looks like on Google Earth or Google Maps.

There are only a few intersections where overpasses are provided, mainly where one 12 lane arterial intersects another 12 lane arterial. Every other intersection has conventional crosswalks, even across the Strip. It works OK for pedestrians going from casino to casino, since they're already at that level, but to be on the sidewalk and have to ascend to the overpass amounts to about 400 feet of out-of-direction travel. They also have escalators, which work a lot better with the climate and financial constraints of Paradise, Nevada than they would in New York.

If you go any place in the Vegas area besides the Strip or UNLV, it's virtually impossible to be a pedestrian.
