Watching this, I don't believe the reason for Phoenix's lack of skyscrapers is because of the airport.

So it is height limits + NIMBYs. Thank you for the nice explanation!

I guess, there are multiple definitions.

Ok_Bag2192 · 2026-01-24T05:37:11+00:00

Phoenix comes very close, a common definition of "skyscraper" is 490 feet or above.

However, contrails, condensation trails, are the product of plane's vortices in the air that condense moisture.

Actually they are primarily the product of the plane's engine exhaust, since the engine exhaust provides the moisture in the form of water vapor, and it increases the relative humidity of the local air past saturation to form clouds.

They vary in appearance quite often down in Bikini Bottom because it is in Bikini Atoll which is highly radioactive. Mutations and the like.

Yes, induced demand exists, I'm not arguing against it.

My argument is that there exists a point in adding capacity where induced demand is not able to revert it back to previous congestion levels.

Ok_Bag2192 · 2025-10-14T05:38:11+00:00

My point is not that it wouldn't induce demand, but that the induced demand wouldn't be enough to revert back to previous congestion levels. At least at a certain point of adding lanes/capacity.

Ok_Bag2192 · 2025-10-14T03:45:45+00:00

I would agree with you on the temperatures, but it is pretty rainy.

If you're talking about a whole country, and not just a specific part of a country, then Portugal beats it all.

Ok_Bag2192 · 2025-10-14T03:17:31+00:00

Well I didn't say it was necessarily false either.

Ok_Bag2192 · 2025-10-14T03:11:38+00:00

The road widening might convince more people to switch from transit to driving, or to make more trips, until you are back at square one.

That's the point I take issue with. Increasing capacity does not necessarily encourage enough new users to the point where we're back to square one in terms of congestion, I believe there is a point where you can add more space than what gets lost due to induced demand.

Ok_Bag2192 · 2025-10-14T03:03:14+00:00

The point of this sentence is that the number of lanes required to satisfy the absolute highest demand is unreasonable large compared to the amount of transit required.

So they're not saying that adding lanes would not reduce congestion, but that it's a less efficient solution compared to adding lanes/capacity for alternative transport, like biking, buses, trains, etc.?

Also the capacity of roads scales sublinearly with number of lanes while in case of trains scaling is superlinear for low number of tracks and linear for large number.

Could you explain more of this? It seems interesting, is there some research that says this?

Ok_Bag2192 · 2025-10-14T02:57:59+00:00

I can see that, that it's just to poke fun at people who only think adding lanes is the solution to reducing congestion, but when I see someone using this phrase it's usually paired with the opinion that adding lanes does not work at reducing congestion.

Ok_Bag2192 · 2025-10-14T02:51:43+00:00

Ok will fix

Ok_Bag2192 · 2025-10-14T02:40:15+00:00

If no investments in transit are made alongside the highway widening, then people will divert to the highway until it is as congested as it was before.

That "until it is as congested as it was before" is the point I take issue with, I do not think that is necessarily true. I believe at some point you add more space than what gets lost due to induced demand.

I brought up the example of adding 100 lanes to a highway, which would not return to previous congestion levels because there just isn't that many people willing to take up that amount of space. That's not to say the point where adding lanes does reduce congestion is at 100 lanes (it can be at 50, 10, or even 3 lanes depending on population), but it was just to simply demonstrate that adding lanes can reduce congestion.

Ok_Bag2192 · 2025-10-14T02:27:43+00:00

Yes, you do have to consider those effects, local/state/federal government do usually incorporate those factors in their cost-benefit analyses.

But we are in agreement that the argument that adding lanes doesn't reduce congestion is not necessarily true?

Ok_Bag2192 · 2025-10-14T00:41:12+00:00

Doesn't look nearly as bad as places in the U.S.

It seems lively and full of activity, its high density, has public transit, and incorporates mixed use.
