Why does it often seem like only China is using modern tech to make real quality of life improvements? It’s the opposite of the US. Seems like that same modern tech is making everything a bit worse day after day.
Take a look at the USA government right now. 😜
But ya you’re right, anyone could have been doing this for a long time. I guess it’s just politics.
They have more catch-up to do. The US already does things like traffic control, but they have a different goal: they want drivers to feel like they’re making progress instead of actually improving things.
For example, we put traffic signals everywhere instead of teaching people to use traffic circles. Why? Drivers like to drive fast and would rather stop than slow down. Traffic circles improve flow, but they do reduce average speed, whereas traffic lights decrease flow and increase average speed. It’s stupid, but we’re entitled jerks who like to show off at signals.

Sorry but I want a source for that claim.
That was a bit tongue in cheek, but my point is that we’re ignoring an obvious solution due to inertia. Here’s a short video by John Stossel interviewing the mayor of Carmel, Indiana, which converted to roundabouts, and here’s a longer CNBC video about them as well. That second video is interesting because it shows that roundabouts started here in the US, but fell out of favor when salespeople pitched signals as cities electrified.
Here’s a video that’s a bit more critical, and the main argument against roundabouts is they’re expensive and disruptive to put in. That’s true, but it doesn’t explain why new signal-based intersections are put in.
Politicians will take the lowest fiction solution to keep their positions. Switching to roundabouts is a large political risk, even if it’s backed by science. People hate change, and roundabouts are annoying to get used to.
More and more countries are using mass surveillance to control the population so China might not be the only ones using it to deal with traffic at all.
“big data” is not generative AI. They’re different things. Just in case anyone read that as “AI fixes things”.
It’s infuriating when a light turns red while only a few of the cars have gone though, makes sense a more intelligent algorithm would be more efficient.
Maybe they could just try a roundabout? Or even better… Ditching the dead end of car dependency for free public transport?
Because phony “AI” is here to save capital, not the planet.
The article mentions specific deterministic algorithms so I don’t think it’s AI in the way youre thinking.
They will truly do anything not to admit the problem is cars
Exactly all this does is create more road capacity which will inevitably lead to more cars and then increased congestion.
This is the big data equivalent of “one more lane”.
China has more public transit of every type than the rest of the world combined at this point, and most of their cities are quite pedestrian centric.
Cars are a luxury outside the rural areas, and they’re a problem, but this is unrelated to that.
It‘s even worse. You need mass surveillance and strip away human rights to do it the way China does it. And I am sorry, but that‘s not worth it. There are countless better ways to deal with climate change because in the end of the day it‘s still a self serving mission for the most part.
Which human right does this strip away?
Privacy obviously. They collect everything about their citizens and use it in every system. They‘re not some super advanced country that simply does tech better than everyone else, they just hoard more data than anyone and use it carelessly everywhere.
No they aren’t. They’re saying smarter traffic systems are an improvement over what we have now. I’ve looked in the article and nowhere do they say cars aren’t a problem, or that emissions is down to traffic lights not cars.
I see so many examples on here and on Reddit of people letting perfect be the enemy of good.
Whether we like it or not, cars will be around for a while. It makes no sense to put zero effort into improving efficiency in the meantime. You don’t have to be so all-or-nothing.
And next year the congestion will be the same as before, except with even more cars and even more emissions.
This is equivalent to building another lane on a highway to increase throughput and decrease traffic jams. In the beginning, emissions will be reduced since traffic jams occur less frequently. And then, through induced demand, there’s congestion again.
Improving car throughput directly leads to increased emissions with a small delay.
From the paper:
Increased speeds from adaptive signals may induce additional travel, as people opt to drive more or travel farther, potentially offsetting some congestion benefits. Our models do not fully capture induced demand due to data limitations, but adaptive signaling generally supports higher traffic volumes and smoother flows.
Yes, and such intelligent systems can also optimize for pedestrian traffic, reducing the time waiting for a walk light, monitor bike lane usage, track dangerous intersections, improve emergency response times, prioritize buses and trams, etc. It’s good for people to be gathering this data and trying to make things better.
Yes, and such intelligent systems can also optimize for pedestrian traffic,
In the US, these types of “intelligent” systems almost always degrade pedestrian traffic quite severely.
Oh so I don‘t have to worry about China‘s increasing emissions output because they use unhinged mass surveillance and terror against the people to put a band-aid on it. Cool…
I would be happy for sensors at traffic lights that detect whether cars are there or not. I don’t consider that to be meaningful surveillance.
But they already have sensors. That‘s not what China differentiates from the rest here.
Did you read the article? Standard traffic cameras or sensors are all you need to implement this. And yes, most places have the technology already in place to do most of it. You just need to add the part to network them and control the lights.
Of course there has to be a sore loser China bad commenter with some made up BS
I am used to tankies on Lemmy but man, if you say China isn‘t an Orwellian surveillance state you‘re just lying through your teeth.
I expect nothing better from someone who uses the word tankie and parrots western propaganda.
I bet you also use “+100 social credits” and been told about this imaginary spying system. Show me proof of this “Orwellian surveillance state”.I know the land Orwell comes from has the most survaillance ameras in the world per capita and nice facial recognition vans driving around and parked in front of stations.
and if you’re a germ you shouldn’t really be talking.
Always on the wrong side of history.
Try protesting genocide and see if you won’t get violently beat up.Sheesh, if I didn’t know better, I’d say I didn‘t just find a Tankie but a full blown Wumao. Talk about projecting.
You indeed really don’t know better.
Enjoy your third consecutive year of recession as a direct result from the terrorist US country blewing up Nordstream ,forcing you to pay for their fracking gas. Companies are leaving your finished shithole. OC germs keep sucking their dicks since they have to be on the wrong side of history all the time.
Tell me how that working out, LOL
Doesn’t China emit like half the amount of carbon per capita compared to the US?
Yes, and they are by far the best in green energy
https://www.carbonbrief.org/analysis-record-surge-of-clean-energy-in-2024-halts-chinas-co2-rise/ And it would be even worse for the US and others if they would produce all the stuff they out now outsource to China.
It’s a typical Chinophobe ‘at what cost’ commenter.
There is literally nothing they can do right.China has a very large capita.
Wait until it learns that lanes can be turned into dedicated tram corridors.
Wait until they run the numbers on carbon emissions of stop signs vs. sensible yielding laws.
Yup. Most European countries barely use stop signs as opposed to the US.
See, this is a reasonable use of horrible dystopian technology.
It doesn’t excuse the rest of it, though.
What’s horrible about traffic signal optimization algorithms? This isn’t GenAI, just an algorithm that looks at traffic patterns and optimizes signals to improve flow. There’s nothing dystopian about that.
