In recent years, with the increasing investment in public transportation infrastructure, the transportation industry has developed rapidly, the scale of the road network has been continuously upgraded, and the level of road transportation services has significantly improved. The demand for safe travel of the people has been increasing day by day, which has led to huge challenges for traffic law enforcement departments in road transportation safety. Some road networks have become saturated in carrying capacity, and the operating pressure on roads and bridges has increased. Many safety hazards in road transportation still exist, among which overloading and over limit transportation is the biggest safety threat.

In order to effectively alleviate issues such as road transportation safety, the scientific and technological community is constantly exploring innovative solutions. In this context, LiDAR technology, as a forward-looking technological means, is gradually becoming an important tool for improving traffic safety. It has multiple advantages in the field of traffic safety, making it an important tool for modern traffic management.

LiDAR, as a remote measurement technology, uses a laser beam to scan and measure the surrounding environment, thereby obtaining accurate three-dimensional map information. Its principle is simple and efficient. By emitting laser pulses and measuring their return time, the distance, velocity, and azimuth of the target can be accurately measured. Compared with traditional technologies, LiDAR has higher measurement accuracy and longer detection distance. It is an active sensor that is not limited by light. It can work during the day, night, and various adverse weather conditions, ensuring the continuity and stability of monitoring. It can achieve all-round and all-weather monitoring of complex environments.

Due to over ten years of research and continuous improvement by Intelly Technology, the laser radar detection system has been successfully applied to thousands of highways across the country. It not only achieves real-time detection 24/7, but also greatly improves statistical efficiency, providing important data support for road management departments.

The laser vehicle length, width, and height detection system under Intelly Technology adopts high-precision LiDAR detection equipment, which real-time and accurately detects vehicle size information to check whether it exceeds the limit. Once an oversized vehicle is found, it will be immediately fed back to the backend data system to promptly stop oversized behavior. In addition, the system does not need to damage the ground, and can be used simply by installing upright poles or installing them on the gantry, greatly reducing the number of equipment deployments and engineering workload, reducing equipment failure rates and maintenance difficulties in the later stage.
