We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.

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.

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.

If you are 'pro car' then you should definitely be resistant to adding lanes (and pro using that money for transit alternatives).

Getting cars off the road is the only thing that's going to make driving less miserable in the kinds of places were adding lanes is suggested.

And maybe a warm take, while this discussion is going on: Whether or not you're pro car or anti car, you're gonna want to provide and improve alternatives to driving. If you're anti car, it's so that you don't need to drive to go from A to B. If you're pro car, it's so that others don't need to drive to go from A to B, keeping more room on the roads for you. Build trains, busses and bike space, and everybody wins.

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.

[–] [email protected] 5 points 1 year ago

What was the population and commuter increases of your area in the last 10 years? I think that is a big factor people don’t consider.

If it’s relatively stable or slow Y/Y then absolutely it’ll help. But if you live in a place where urban sprawl is the city’s building mandate for the next 20 years, it’ll be like Los Angeles traffic in no time.

[–] [email protected] 1 points 1 year ago

Even 290 in Houston got more lanes recently and it's like night and day.

It's almost like it's more nuanced than loud people want to admit.

As with many things there's not a clear cut answer. I think you could make a strong case for the Katy Freeway expansion being a failure where those resources would have been better spent on other forms of transportation. I'd agree that adding lanes is not always a bad idea, but blindly adding lanes like the US has done for decades has not been a good thing overall, imo. We're dependent on cars for everything, they're heating up the planet and they're a very inefficient solution to the ultimate problem of getting people from point A to B. I'm not so much anti-car as anti-inefficient travel that has saddled us with tons of negative aspects to city life.
