Nanoradar Empowered Radar-Vision Integrated System for Precision Signal Control and Efficient Traffic Flow Detection

"With the surge in urban vehicle ownership, traditional video surveillance faces bottlenecks such as low visibility and missed multi-target detection. During the 2024 evening rush hour in Chongqing's main urban area, heavy rain caused 43% of electronic police systems to fail, triggering multiple rear-end collisions. Data shows that traffic accidents during severe weather increase by 2.3 times compared to normal conditions, highlighting the urgent need for all-weather intelligent sensing devices to ensure smooth road network operations."

Business Challenges

Insufficient Dynamic Traffic Signal Adjustment: Real-time traffic flow changes, but signal control lacks dynamic optimization, leading to inflexible traffic light timing. This easily triggers a "chain red-light effect," worsening intersection and surrounding congestion while reducing traffic efficiency.

Lagging Urban Road Violation Monitoring: Speeding, wrong-way driving, and lane-changing violations rely on traditional monitoring methods with insufficient real-time accuracy.In 2023, such violations caused 1.75 million road accidents and 500,000 deaths, demanding urgent intelligent regulatory upgrades.

Weak Intelligent Sensing in Highway Networks: Low coverage of smart monitoring equipment prevents all-weather, real-time perception. Traffic incidents still rely on manual identification, resulting in low discovery efficiency and slow response times, failing to meet emergency and management needs.

Customer Benefits

Multi-Dimensional Data Support (e.g., flow statistics, congestion analysis) aids dynamic traffic control strategies (e.g., signal timing optimization, temporary lane adjustments), reducing reliance on manual experience and enhancing management efficiency.
Real-Time, Accurate Target Detection (e.g., vehicle/pedestrian/cyclist position, speed, trajectory) minimizes manual monitoring efforts, shifting staff from "passive screen-watching" to "active decision-making" for rapid response to anomalies (e.g., illegal lane changes, sudden stops, collision risks).
Automated Traffic Incident Recognition (e.g., accident location, violation capture) reduces on-site inspections, lowering personnel exposure to high-risk environments.
