🚦 The Challenge Banan Interchange is a critical gateway connecting the G75 Lanhai Expressway to downtown Chongqing. Surrounded by schools and daily commuter flows, it suffered from severe "highway-urban" synergy congestion—peak-day delays hit 671 minutes (nearly 11 hours).
📡 The Solution We deployed ClairWav, a millimeter-wave radar system with edge computing, to monitor traffic in real time. The system captures volume, speed, and queue length, then automatically adjusts signal timing—enabling predictive, dynamic, and demand-responsive control.
Smoother commutes for thousands of daily travelers
🔁 Why It Matters This isn't just a local fix—it's a replicable model for highway-urban interchange bottlenecks nationwide. Radar-based "Highway-Synergy" control proves that smart infrastructure can deliver real, measurable relief.
