Coordinated traffic lights

Upvote:1

It is mathematically impossible to do even for both directions at once, as you cannot control the distances between traffic lights: the 'green waves' need to travel with you, at the same speed, and at the same time the ones for the opposite direction needs to travel too, but in the opposite direction. They simply will not hit each other exactly at all crossings, which makes it useless. Unless you want all cross traffic to stop for ten minutes.

Well, I'm not sure there's a ranking anywhere, but Manhattan would seem to do pretty well, and there's evidence to back it up.

NY Daily News reported that an uber driver hit a 'record' 240 green lights in a row driving in Manhattan, and recorded the event as well.

It's called a Green Wave. Co-ordinating it on two-way streets with varying distances between the junctions is tricky.
