A new study found adaptive traffic signals powered by big data reduced peak-hour travel times by 11% in China’s 100 most congested cities – saving 31.73 million tonnes of CO₂ annually.
A new study found adaptive traffic signals powered by big data reduced peak-hour travel times by 11% in China’s 100 most congested cities – saving 31.73 million tonnes of CO₂ annually.
Urban congestion is a pressing challenge, driving up emissions and compromising transport efficiency. Advances in big-data collection and processing now enable adaptive traffic signals, offering a promising strategy for congestion mitigation. In our study of China’s 100 most congested cities, big-da...

You're viewing a single thread.
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…
Doesn't China emit like half the amount of carbon per capita compared to the US?
China has a very large capita.
What's your solution to that
China already "solved" it with the one child policy. They will have the most massive population decline ever in the coming decades. It will probably destroy their economy.
It's not that there should be a solution per se, more that it impacts their emissions per capita. When person density goes up average per person emissions go down, simple as.
Yes, and they are by far the best in green energy

It's a typical Chinophobe 'at what cost' commenter.
There is literally nothing they can do right.One issue with that is China is still a heavily bike and moped driven country. The issue is when more of their population is able to afford cars. So they could still "catch up".
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.
