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...

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.
how would that even work, if there's no indication that driving too fast was the reason for the red light?
do these actually include some sort of screen that tells the driver they were too fast and that's why the light turned red?
I'd imagine that this "feature" would only result in more frustration, and thus more speeding, instead of less.
I think it's often the opposite, a traffic circle is much less intelligent but quite effective at increasing traffic flow. We can't put them everywhere, but we should put them in more places.
