For critics of widening projects, the prime example of induced demand is the Katy Freeway in Houston, one of the widest highways in the world with 26 lanes.

Immediately after Katy’s last expansion, in 2008, the project was hailed as a success. But within five years, peak hour travel times on the freeway were longer than before the expansion.

Matt Turner, an economics professor at Brown University and co-author of the 2009 study on congestion, said adding lanes is a fine solution if the goal is to get more cars on the road. But most highway expansion projects, including those in progress in Texas, cite reducing traffic as a primary goal.

“If you keep adding lanes because you want to reduce traffic congestion, you have to be really determined not to learn from history,” Dr. Turner said.

But think of the alternative. In Japan the trains arrive every 10 minutes are publicity subsidized so cost is minimal and because of this there exists an entire generation of train nerds that just want to go out and photograph trains. Are you gonna let the nerds win?

Can't let a bunch of train virgins take away my Ford F-750.

12 yards long, 2 lanes wide,

Yup. Been plenty of studies to show that increasing lanes only alleviates traffic in the short term and long term only makes it worse. Better to spend money on trains and busses that actually work and get people where they need to go with minimal hassle and a reasonable cost than to do this crap.

[–] mojofrododojo@lemmy.world 27 points 1 year ago

to me it's like the military industrial complex - they don't care what evidence supports, they want their fucking money and they'll keep building roads until it's a giant parking lot from sea to fucking sea. we could have an ecosystem, but fuck you, because cars.

This is because the extra lane allows demand to change. It is not congested so people feel ok building and moving to further out suburbs. This continues until demand has increased to cause delays.

Note that Houston and Paris have about the same population. Paris is 1/3 the size. They are actually removing a lane from their loop highway and planting trees, and turning another lane into busses only. Only considering transportation, I would much rather live in Paris.

[–] kyle@lemm.ee 26 points 1 year ago (1 children)

If you also consider the weather and politics, I would still much rather live in Paris.

[–] deadsenator@lemmy.ca 7 points 1 year ago

Let's list the reasons why Houston is better....hrmmm...I got nothing.

[–] AA5B@lemmy.world 6 points 1 year ago* (last edited 1 year ago) (1 children)

But what options do you have in Houston, compared to Paris?

You can’t just not widen roads but instead

— less sprawl - places to live closer to each other and to destinations

-- useful transit or short distance commute options

-- remove bottlenecks

These are a lot harder to do, and I don’t imagine Houston even considered it

Simply make it a single flat wide open surface, drive where you're trying to go in a straight line.

If you die, you die.

Why, oh why didn't they build 27 lanes?!?

[–] JackbyDev@programming.dev 20 points 1 year ago

99% of urban planners stop just one lane short of permanently solving traffic for good.

[–] FlyingSquid@lemmy.world 45 points 1 year ago (2 children)

For anyone wondering what that looks like-

Absolute insanity.

[–] Noughmad@programming.dev 36 points 1 year ago (2 children)

Where are the bridges? How do you walk from one side to the other?

Oh yeah, right, of course. But how do you even drive from one side to the other?

Hey this looks just like my failed Cities Skylines build!

[–] CanadianCorhen@lemmy.ca 41 points 1 year ago (1 children)

The fools, if they had made in 27 lanes they would have been fine!

[–] TheWoozy@lemmy.dbzer0.com 6 points 1 year ago (1 children)

27 is an odd number, do I assume the center lane switches direction for rush hour. That's sure to fix it.

I live in Katy. Driving through this from 4-7 pm is an absolute nightmare. Horrible traffic jams, erratic drivers and multi-car accidents daily. Mornings aren’t fun either.

[–] hoodatninja@kbin.social 14 points 1 year ago

After Hurricane Katrina I lived in Houston for about six months. I still have nightmares about your highways. I don’t know how y’all do it.

[–] grte@lemmy.ca 28 points 1 year ago (6 children)

Who knew that adding complexity to a system entirely reliant on millions of autonomous drivers who only communicate with each other through lights, horns, and middle fingers would slow things down.

[–] Uncle_Bagel@midwest.social 15 points 1 year ago

Lived out there for a few years and i can tell you no one is communicating through the lights on their cars.

Houston is commonly used as an example for what NOT to do, when it comes to civil planning and development.

Literally play 2 minutes of cities skylines and you will discover how bad of an idea this is lmao

If you've got more lanes then you've got more lanes for idiots to cross right before the exit they need to take because they weren't paying attention and they MUST take this particular exit or their life is over or something.

Just one more lane bro. I promise. It'll fix everything, I swear. Just one more lane bro.

My only time in the Houston area, and visiting friends staying in Katy TX, and I learned how quickly I hated the traffic there. This makes sense

[–] Bye@lemmy.world 9 points 1 year ago (1 children)

The purpose of widening the highway isn’t to make individuals move faster or to solve congestion. It’s to move more individuals, and therefore more money.

Great for sidewalks, bike paths, and trains, but terrible for cars.

It worked great at the start, but the Houston area population just kept exploding at unprecedented rates.

The Greater Houston area grew by 70% between 2000 and 2020 - largely on the West side. Of course a 30% capacity improvement couldn't keep up.

[–] BeigeAgenda@lemmy.ca 5 points 1 year ago

If they had just built it with 52 lanes!

/s

[–] donut4ever@lemm.ee 5 points 1 year ago

They missed it by one lane. They only needed one more. Lol

[–] Hazdaz@lemmy.world 4 points 1 year ago (1 children)

Anti-car people use this to try to explain that adding more lanes doesn't help traffic congestion. Except that every highway system is different and the vast majority of them don't have anywhere near those number of lanes. Adding 1 lane to a 2 lane road would dramatically help traffic situations.

[–] Stuka@lemmy.ml 9 points 1 year ago (2 children)

Can confirm. My area added a third lane to the highway over the last 10 years or so. So much better than before. One grandma can't bring the entire highway to a snails pace anymore.
