VIVOTEK Deploys AI Video Surveillance on Danjiang Bridge for Traffic Operations
Smart operations · Water and transportation engineering
VIVOTEK and SI partner Cheng Li International deployed 40 cameras with AI analytics across Danjiang Bridge, supporting traffic monitoring, vehicle classification, and threshold alerts for its control center.
The Danjiang Bridge features the world's longest span for an asymmetric single-tower cable-stayed bridge, measuring nearly one kilometer in main span and accommodating mixed traffic including pedestrians, bicycles, buses, and motor vehicles. To ensure round-the-clock operational safety, a dedicated bridge traffic control center was established. VIVOTEK partnered with system integrator Cheng Li International to deploy 40 specialized cameras across the bridge, utilizing weather-resistant PTZ domes along with bullet and license plate recognition models to withstand coastal wind and salt spray. The system incorporates AI video analytics for traffic counting, threshold-based alerts, multi-vehicle classification, and historical footage re-indexing.
Key takeaways
- VIVOTEK and Cheng Li International deployed 40 specialized cameras across Danjiang Bridge, using high-resolution PTZ domes built for coastal salt spray.
- The dedicated bridge traffic control center employs AI analytics for real-time flow alerts, vehicle classification, and pedestrian separation.
- The surveillance platform supports rule-based historical video re-indexing and CSV report exports to aid traffic timing and operational management.
