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.
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.
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.
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.
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.
You wanna reduce traffic times with these better lights? Think of all the billions of dollars lost to advertisers since people won’t be forced to look at their ads now while waiting!
“big data” is not generative AI. They’re different things. Just in case anyone read that as “AI fixes things”.
It’s a confusing situation, because big data is what it sounds like. Large amounts of data on actual events. But it doesn’t mean they didn’t use AI to help interpret the data, or to come up with the adaptive traffic signaling.
It’s weird cause technically adaptive traffic patterns are trained using tools like reinforcement learning, which is technically AI, however it’s the broad term AI and not GenAI.
They will truly do anything not to admit the problem is cars
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.
Your take is that changing traffic management is a violation of human rights?
Your bad faith argument aside, they absolutely do use technology that violates human rights and integrate it in this system. Think about why smart cities are controversial and amp it up to 11. That‘s China managing their population. Point systems that prevent you from air travel or entering other provinces because you dared criticize the almighty government do violate the basic human right of free speech and control traffic at the same time.

That’s… just not real… Your understanding of Chinese policy comes from curated western sources with vested interests in putting a dystopian and totalitarian understanding of China and its government in our countries’ people (we’re both westerners). There are systems in place to prevent certain convicted criminals from freely moving around there country, but that has little to do with criticising the party.
Regardless, big data on traffic doesn’t imply knowledge about the particular vehicles and drivers inside said vehicles. You’re just going ahead and assuming “dystopian control of people” because it’s China.
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.
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.
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.
In Switzerland we have sensors in the streets at most crossings. And behind it I assume, is a determinate algorithm whoch decides who has green for how long. This mainly is done to avoid the backing up of one crossing into another.
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…
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.
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.
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.
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.
I pass like 15 lights on my commute and the amount of time standing still for NO REASON is absolutely infuriating. How much could it possibly cost to add a simple sensor? No cars coming from the sides? Light stays green! But no, it’s all just dumb timers instead…
Interestingly, some lights are set up to deliberately slow down speeders. If you are above the speed limit, they turn red, just to slow things back down. Unfortunately, most of the people involved never put cause and effect together.
What annoys me is the road to work in the morning actually seems to do the opposite. It’s a 35 or 40mph road, but if you do 40 you’re not gonna make it through without stopping. But if you do 50-60? No stops.
Once again though people don’t pick up on this.
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.
The horrible and dystopian part for the comment above yours is the fact that it happens in China, which is ontologically bad and oppressive
In my little Southern US town the lights seems to work logically and traffic flows nicely, noticeably so. I’m never sitting at a light screaming, “Oh FFS turn!” or “Why did that light change and there are no cars?!”
Traffic only gets a bit thick on the main road in late afternoons. Not much to be done there, it’s a major east-west thoroughfare connecting several towns.
Have no idea how they’re doing this. Sensors I’m guessing? Seems like we’re too poor for fancy civil engineering like that and I’m sure we can’t afford what the article talks about.
Anyone know how that might work?
Sensors on a main road and well set timers after a few months of data can do wonders and be extremely low cost, but it requires some upfront spending and enough public will to put up with bad traffic until everything is tuned.
