Changsha Rongtai Plaza Holographic Smart Intersection

The holographic intersection at Rongtai Plaza involves installing radar video fusion devices (radar ANPR camera) on signal poles at the intersection to sense the traffic. These devices are used to collect all the traffic data of vehicles, pedestrians, etc. Pedestrian data, vehicle data, and traffic data are presented from a bird’s eye view. Through real-time collection, analysis and judgment of traffic data and turning data at each intersection, Real-time optimization plans are issued through the signal control system to improve the traffic efficiency at the intersection.

The traffic volume at the intersection can be coordinated to optimize the precise intersection signal control implementation.
