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-data empowered adaptive traffic signals reduced peak-hour trip times by 11% and off-peak by 8%, yielding an estimated annual CO₂ reduction of 31.73 million tonnes. Despite an annual implementation cost of US$1.48 billion, societal benefits—including CO₂ reduction, time savings, and fuel efficiency—amount to US$31.82 billion. Widespread adoption will require enhanced data collection and processing systems, underscoring the need for policy and technological development. Our findings highlight the transformative potential of big-data-driven adaptive systems to alleviate congestion and promote urban sustainability. Big-data empowered traffic signal control in China can reduce vehicle trip times, creating potential reduction of 31.73 million tonnes (Mt) of CO2 emissions annually and US$31.8 billion benefits per year.
Honestly I’ve seen round abouts in the US and while I totally think their more efficient and causes less wrecks statistically. People are fucking idiots. Everyone complains and thinks their worse and hate them to hell and back. No amount of facts or convincing will change their minds. It’s insanity. People are so resistant to change it’d incredible the mountain out if a mole hill they will make it out to be.
It doesn’t help that we use them poorly. We have one between a stoplight and a shopping area, and it always gets backed up. They’re never in high traffic areas, so drivers never get used to them. I want to replace highway intersections with traffic circles instead of putting them in random neighborhoods.
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.
