Application Case Study: ClairWav Microwave Radar for Train Station Traffic Optimization

Location: Suzhou, Jiangsu Province, China

Challenge
A major train station in Suzhou, adjacent to a key urban arterial road, faced severe congestion due to unpredictable passenger vehicle surges. Fixed-time signal control could not adapt to random high-volume events, causing oversaturation and reverse overflow that disrupted main road traffic.

Solution
An intelligent signal optimization system was deployed, powered by ClairWav microwave radar detectors. The radar provides real-time, multi-lane vehicle detection with up to 350m range, enabling:

• Dynamic, second-by-second signal timing adjustments
• Proactive queue management to prevent overflow
• All-weather reliability (rain, fog, or darkness)

Results

• 114 minutes (1hr 54min) reduction in weekend congestion
• Main arterial flow stabilized; reverse overflow eliminated

Conclusion
The ClairWav radar-enabled system effectively mitigates random congestion at high-volume transport hubs, delivering measurable improvements in traffic efficiency and reliability.
