Caption: Photo collage of a beach in Alexandria, Egypt, showing a progression in 3 images:

  1. Alexandria “Problem” - empty beach + walking street + 6 lane road with medium traffic + dense mid-rise buildings (likely housing)
  2. Alexandria “Solution” - empty beach (doesn’t seem to matter) + narrower walkway or sidewalk + 10 lane brand new and empty road + tiny sidewalk + the same buildings
  3. Alexandria “Results” - crowded beach + crowded beach walkway + traffic jam on the 10 lane road

      Anyone should intuitively understand this if they’ve watched people try to merge. More lanes, more god awful merging and bottlenecking at exits.

      But I guess everyone forgets this intuitive wisdom when they start asking for more lanes.

        An infinitely wide road couldn’t be effective unless it was also infinitely long. Cars enter and edit at one edge, and transferring lanes reduces capacity, so adding lanes had diminishing returns.

            More capacity on the roads will make driving a more attractive option to more people, both for journeys they previously made by other means and those that they wouldn’t have taken, which leads to more cars on the roads until the congestion is as bad as it was before.

        all you’ve illustrated is that the only place my statement doesn’t apply is in a theoretical (and impossible) fantasy, but you do then go on to explain the means by which what I said is true.

        so… thanks?

            It’s not the width of the highway that CAUSES the traffic alone, it’s the bottlenecks and access. It’s not the induced demand alone that causes the issue, it’s the offramps and local streets that ruin the new highway.

            I’m pretty sure I thanked you explaining how my initial statement was correct.

            It’s a conversation bro. We agree about some parts and have other thoughts about other parts.

            and I’m enjoying the conversation, bro. your “other” thoughts seem to be an explanation of how my statement is correct and why.

      Not if all people that would possibly go on the road can fit on it. And I’m 100% positive that this one extra lane will accomplish that, trust me broo!
