    What is this meme template called? I always chuckle at the different topics but don’t know anything about where it comes from.

    I think a diverging diamond interchange is actually a pretty elegant solution. That being said, I’d rather have public transport than better traffic infrastructure.

      I’ve read descriptions of how they work numerous times and cannot wrap my head around how having traffic going opposite directions cross paths does anything helpful.

      Great, you’re now on the appropriate side to make the turn at the far side of the interchange, so the people making the turn don’t have to cross traffic to do so, at the cost of every car that crosses the interchange now having to cross traffic twice.

      What?

      my city is literally prohibited from using public funds for any type of train because of some GOP devil magic thing – so all we have is busses, which suck because you’re still beholden to traffic jams and lights and speed limits and roads. pointless and not even a sense of whimsy or transcendence

      I think the diverging diamond interchange is terrible. Because of the crossover, traffic can only cross the interchange in one direction at a time, so most of the traffic in the interchange is not moving most of the time.

      A pair of roundabouts connected to on ramps eliminates the danger of left turns without stopping the majority of traffic most of the time.

      A massive overbuilt interchange that cannot function without traffic lights is the opposite of elegant.

        I’m not so sure about that. The appropriate use of a diverging diamond is when there is a lot of traffic entering and exiting from the ramps, and some of that traffic can go at the same time as the traffic crossing the interchange in one direction.

        I don’t live in the USA but don’t these mostly replace intersections that already have traffic lights?

        Also there is a proposed variant without traffic light called DCMI but I don’t think there has been any build due to patents or something.

    I always wondered that.

    Is it traffic engineers who suggest adding another lane? Or is it stupid people who can’t read data and demands it?

      Both. 1980s Era civil/traffic engineers in NA were all trained for car=future=build road. Nowadays most traffic engineering/city planning schools teach multimodal transportation as The Way, but decades of car washing our cities has resulted in an almost total collapse of public support for anything except another lane. Luckily, most people sub-30 are aware of this and are slowly becoming politically active. Public opinion will shift slowly over the next decade or two and eventually the traffic engineers will be allowed to do the right thing.

      Wanna make a difference? Get some of these stickers and slap em up everywhere. I’ve still got a few left over to put places.

      Go to your city “public opinion” sessions on zoning and highway design. One of our new circumferential highways has the first inverted diamond because some radical urbanists sandbagged the public hearing. Showing up to these things can make a big impact.

      That I’m actually for, let the people who use these roads pay for them. All the while, I’ll be laughing at them as I bike on through.

      The toll is actually used to pay for the original construction costs. Isn’t that fun? So, when the road needs to be replaced in 30 years, the tolls spent all that time paying for the original road instead of for this looming replacement.

        Yeah true. I also didn’t realize how much the infrastructure of where you live impacts your life and your wellbeing

    intersections should either be contractible or homotopy equivalent to the circle. any intersection outside of those two homotopy classes will always be a worse solution than just improving the public transportation infrastructure

      But what would we call that?

      A circle-near?

      A ball-approximate?

      A curved-around?

      An oval-almost?

        I’m assuming they are referring to the fact that this is an unironic usage of a format that typically contains an ironic message. But I think this format is used to express counter narratives of all kinds, both serious and unserious, so I wouldn’t call this an incorrect usage. I mean, the format already has some bone hurting juice energy to start with, so I think gatekeeping its usage is maybe outside of the spirit of the template

      Haha yeah, that’s like validating traffic engineers but I get the spirit of the message
