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.
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.
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.
They will truly do anything not to admit the problem is cars
