    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.

    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.

    Not on bicycles, that’s for damn sure!

    Wanna hear something stupid and fucked-up? Listen to this: in my city, getting a license to serve alcohol comes with a minimum parking requirement. Not maximum, minimum. In other words, if you as a business want to be allowed to get people drunk, you effectively must facilitate drunk driving by building extra parking for them. It’s absolutely ludicrous and ass-backwards!

    Hi, civil engineer* here. Nah, fam: a lot of the time we don’t even use formulas; we just look shit up in tables or interpolate on a graph!

    (* To be fair, (a) I specialized in traffic, and (b) I didn’t do all that much professional work as a civil engineer before switching to software “engineering” instead. That’s even less mathematically rigorous most of the time, LOL.)





  • Right, but that’s exactly my point, it likely wouldn’t just be one flat color. If you scale it by population density you get a map displaying the average distance between kids and parents compared to the average distance between any two people which I would expect to be 1. non-uniform…

    My point was that I expect exactly the opposite: that the average distance between kids and parents is pretty much exactly proportional to the average distance between any two people.
