Introduction

Radar sensors for smart city applications use radio-frequency (RF) waves to detect objects, movement, distance, and speed in urban environments. Unlike cameras, radar can operate reliably in low visibility conditions and does not capture identifiable imagery, supporting privacy-friendly sensing. In China, radar sensors are deployed for traffic flow optimization, intersection safety, pedestrian and cyclist detection, parking management, perimeter security, and infrastructure monitoring.

These sensors can be installed roadside, on streetlight poles, or integrated into smart infrastructure nodes. Advances in mmWave radar, signal processing, and AI-based classification are expanding use cases beyond traffic counting to predictive analytics and real-time control. As urbanization and smart mobility initiatives accelerate, radar sensors are becoming essential sensing layers within smart city platforms.

Future Outlook

By 2032, radar sensors in China will be deeply integrated into connected infrastructure and multi-sensor fusion architectures. Cities will increasingly deploy radar for continuous monitoring of intersections, school zones, transit corridors, and critical assets. Radar data will feed into AI-driven digital twins for predictive traffic optimization and safety risk forecasting.

 Integration with V2X and connected vehicle ecosystems will expand, enabling cooperative perception and real-time hazard warnings. Wider adoption of edge processing will reduce latency and bandwidth costs. Overall, radar sensing will become a core “always-on” infrastructure component supporting safer, more efficient, and privacy-conscious smart cities.

China Radar Sensors for Smart City Applications Market Trends

• All-Weather, Day-and-Night Sensing Adoption for Smart Mobility
  Cities in China increasingly prefer radar because it performs reliably in fog, rain, dust, and darkness. This reliability improves intersection safety and traffic monitoring in challenging conditions. Radar supports accurate vehicle counting, speed detection, and lane-level tracking. Municipalities adopt radar to reduce dependence on optical sensors that degrade under poor visibility. Consistent sensing improves automated signal timing and congestion management. This trend is accelerating deployments at critical junctions and high-incident corridors.

• Privacy-Preserving Sensing Shift Away from Camera-Only Systems
  Privacy concerns are shaping sensor selection across China’s smart city programs. Radar sensors do not capture facial or license-plate imagery, improving public acceptance. Municipalities are using radar as a primary sensor for traffic analytics and pedestrian detection. Regulations and citizen expectations are influencing procurement requirements. Radar offers strong functionality while minimizing surveillance perceptions. This trend is expanding radar adoption in public-facing deployments.

• Integration of Edge AI for Real-Time Classification and Decision Support
  Radar sensors are increasingly combined with edge AI processors in China for local object classification. On-device analytics reduce latency and enable real-time incident detection. Edge intelligence supports adaptive signal control and pedestrian protection systems. Local processing reduces cloud bandwidth requirements and improves cybersecurity posture. AI models improve classification of vehicles, cyclists, and pedestrians. This trend is increasing the value and complexity of radar-based smart city nodes.

• Multi-Sensor Fusion with Cameras, LiDAR, and Acoustic Sensors
  Smart city deployments in China are moving toward sensor fusion to improve situational awareness. Radar complements cameras by providing robust speed and range measurements.
