And traffic moves, of course, hopefully faster in a highway when things are flowing.
So what you have is that you have to build this hierarchical infrastructure in a way where traffic is denser but moves faster as these levels of hierarchy increase.
And this turns out to give you just such a way that gives you a scalable system.
It's kind of interesting, but that's why that comes from.
So when you're flying, you will see the traffic flow being denser and traffic flying more quickly, more faster in the highways that you see in the cities.
And this is why highways are very susceptible to jamming.
Because they're already dense and they rely for not jamming on a fast flow.
So the moment that flow is slowed down, you see this, for example, at toll booths, tollway, toll parlors, then the whole thing jams, right?
Right.
It's good only on the average for the entire city.
It's what we physicists like to call mean field approximation.
So you take just a big average.
But of course, you and I and everybody else is not the average.
There's no one who's well represented by the average.
So this now requires that we look closer as to how people actually interact with others and, you know,
the good and the bad that comes from that, the richer and poorer, and so on.
So this is important for real cities.
And, you know, there are general things we can still say that usually people with more interactions tend to be richer, more educated, and so on.
So there's sort of a knob there that still persists, that this idea that...
More interactions is a pathway.
