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.
Point systems that prevent you from air travel or entering other provinces because you dared criticize the almighty government
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.
