World's first city-scale AI traffic lights
142 intersections upgraded from fixed-timing to AI-adaptive control — traffic efficiency improved nearly 20% citywide. 'Lights watch cars' instead of 'cars watch lights'.
Solutions
Real-time traffic flow analytics, AI-adaptive signal control, and digital twin platforms — from intersection to metropolis.
探索方案Real-time traffic flow collection, incident detection, and infrastructure monitoring across urban arterials and highway networks. Our Road Network AI integrates multi-source data — cameras, radar, and vehicle-road-cloud coordination — to power smart signal optimization, digital twin platforms, and predictive traffic management.
From the world's first city-scale AI traffic lights in Zhangjiakou (142 intersections) to autonomous driving corridors in Guangzhou Nansha, this solution scales from intersection to metropolis.
142 intersections upgraded from fixed-timing to AI-adaptive control — 'lights watch cars' instead of 'cars watch lights'.
Replace fixed-timing traffic lights with AI-adaptive control. Cameras at each intersection detect real-time vehicle counts, queue lengths, and pedestrian presence — signals adjust phase timing dynamically to maximize throughput and minimize wait times.
In Zhangjiakou, 142 intersections achieved a 20% traffic efficiency gain. Emergency vehicle preemption and transit signal priority are built-in.
Build a real-time 3D digital replica of your road network. Every vehicle, signal phase, and incident is visualized on a unified dashboard. Simulate traffic scenarios before deploying, predict congestion before it happens, and coordinate autonomous vehicle corridors with sub-meter precision.
Deployed in Guangzhou Nansha's autonomous driving zone — coordinating mixed traffic of autonomous and human-driven vehicles across 100+ km of smart roads.
