> I’ve seen the wave idea implemented, and if you can actually drive the speed limit they are quite nice.

A bunch of the streets in my city do this, and it's awesome. Particularly when there's another car that doesn't know about it, so they're constantly speeding to next red light, where my relatively sedate pace gets me constant green lights, and I smile as I repeatedly pass the speeder that is trying to accelerate from a complete stop.

There's only 2 streets that i know of that were designed this way, but like i mentioned, the streets are usually too encumbered to actually get it to work. I haven't been downtown since pre-covid to know if they are even attempting to still do it.

It works incredible well for bicycles though, as is stated in the article 17% decrease of travel time has been shown. This mirrors my experience, though it suffers alot if there is one or two non synchronized lights at the edges of a wave.

Quite a few streets in my city do this, but only if you drive 10mph over the speed limit.

[giraffe_lady]

Yeah chicago works like this if you go 10 over and blast every yellow. Not sure if that's just civil engineering realism or what.

[dylan604]

I thought the whole point was to reward/encourage drivers for driving the limit, not speeding. This seems very odd

[JohnFen]

I've seen this a number of times. One time, I got a clue as to how it comes about -- I travelled a 35MPH road with synchronized signals, and the city reduced the speed limit to 30, but didn't go to the trouble to adjust the light timing to match.

[nomel]

Yes. It directly conflicts with the large signs they have posted, touting the benefits of going the speed limit.
