World's first city-scale AI traffic lights
The world's largest holographic intersection deployment —142 intersections in Zhangjiakou's city center upgraded from fixed-timing to AI-adaptive signal control. This pioneering project achieves two fundamental transformations: from manual/fixed timing to AI-driven timing, and from 'cars watch lights' to 'lights watch cars'.
Traffic efficiency improved by nearly 20% citywide. Each intersection is equipped with perception and intelligence —giving traffic lights 'eyes' and a 'brain' —turning ordinary junctions into smart, responsive AI intersections.
Yangshuo digital intersection upgrade
SuperVision led the traffic optimization and AI upgrade of Yangshuo's busiest roundabout —the Shima Yuanpan intersection —along with two other key scenic area junctions. Despite a 61.26% increase in visitors during the 2023 Golden Week holiday, the upgraded intersection saw its congestion index drop 11.2% year-over-year.
By the 2024 Labor Day period, congestion delay at the same intersection had plummeted 67% compared to 2023 —a dramatic improvement for one of China's most popular tourist destinations.
