    This is the ideal intersection. You may not like it, but this is what peak performance looks like.

      The zero choice interchange is fucking hilarious.

    Actually, this is a traffic simulation from the game Cities Skylines (think SimCity). TMPE and NeXT are traffic mods to add more control to traffic flow in the game.

      Yeah, I thought the color and rendering and even the animation looked familiar. Still an interesting study but not quite analogous to real-world.

      Also worth noting that while it’s a great game that’s a lot of fun, one of the chief gripes about it is that the AI that controls how vehicles route themselves is notoriously terrible, to the point that if you don’t plan your city around its foibles your eight-lane highways might as well be single lane roads. Applicability of this video to real-world traffic flows will necessarily be limited.

    I don’t know whether the physics or the visual effects are broken, but the number of vehicles overlaid atop each other make me skeptical about the numbers.

    Well one thing that RARELY happens in real life is the simultaneous left/right turn onto the same road with both cars keeping in their closest lane.

      You know, there’s a road near my house that actually has reflective rubber pylons in between the left and right lane, for say 50 feet or so, so people have to turn into their own lane. It helps get cars through more quickly, and it allows people making their free right turn to be confident that people turning left are not going to enter the right lane. Makes people less tentative to go when it’s their turn.

      I’m pretty sure that around where I live the only way such pylons would work is if they are 20 feet tall masses of concrete and steel. If it’s just those plastic orange reflective types they’ll just get mowed down.

    Woah, that’s nuts. The only thing is, those simulators I assume must think that everyone that comes up to the intersection understands how it operates. How many people do you see come up to roundabouts and just stop while waiting for everyone to go?

      That turbo-roundabout looks like something that people would always be getting wrong, no matter how good the signage is.

      I know, people screw up normal roundabouts enough in the US that i find them somewhat stress inducing.

    Did anyone else notice that cars can apparently go underneath other cars or semis in this visual? Let’s hope the numbers reflect a more accurate model, but dammit that was interesting still.

      “cars can apparently go underneath other cars or semis”

      Well, at least one Tesla Model S attempted it.

      Too soon?

    Except, at least visually, that flow model is horribly wrong...

    Watch closley at how many vehicles literally drive through eachother...frequently occupying the exact same physical space...

    Second, although it shows the wet dream of people making a left turn, and a right turn, into the same two-lane road, at the same time, in a perfect maneuver...this will never, ever, happen until we have 100% automated roads...

      I was willing to let ghost cars slide (because, reletively, it evens out?), but I became fully disillusioned when the standard cloverleaf at 4:50 ran like shit. Lane 1 was all backed up due to the merging on-ramps... WTF?

    These remind me a lot of my Cities Skylines city.

    Unfortunately, especially the ones “without traffic lights”.

      I never put traffic lights in my Cities Skylines cities because they seem to create more traffic jams than they solve. You can honestly get by with only using two lane roads and freeways in your entire city and it still functions just fine.

    Our city has gone fucking crazy with roundabouts, costing us millions of dollars trying to fix what isn’t broken in most cases.

    I imagine our traffic engineers go to annual conventions and get envious of other cities with all these fancy improvements and come home and convince city council that we need them too.

      Roundabouts absolutely suck in Paris when there is grid lock. 3 lanes with 6 entry/exits with people crossing you perpendicular aggressively inching directly to their intended exit. The only rule is don’t hit anyone.

      Ya, this was “fun”. I thought I was pretty good at round-abouts, but 12 streets and 6 lanes? Ya, screw that.
