In recent years, with the accelerated advancement of China’s national transportation strategy and digital traffic initiatives, regions across the country have launched the construction of “technology-driven overload control” systems. Among them, the Off-site Overload Enforcement System has become a key force in modernizing the governance of oversized and overloaded vehicles. Its efficient, precise, and intelligent enforcement model is transforming traditional approaches and driving a new wave of traffic governance reform nationwide.
High-tech Empowerment: “Electronic Sentinels” Enforcing 24/7
The Off-site enforcement system integrates advanced technologies such as dynamic weighing (WIM), vehicle dimension measurement (ADM), intelligent vehicle recognition, high-definition video surveillance, LED real-time information display, and edge computing management. Dynamic weighing sensors, laser imaging devices, and HD cameras deployed at key road points can accurately detect vehicle gross weight, dimensions, speed, axle configuration, and license plate information while vehicles travel at 0.5–100 km/h.
Through deep collaboration of neural network algorithms, adaptive filtering algorithms, and AI edge computing, the system can automatically identify overloaded or oversize vehicles and generate a complete legal evidence chain. Blockchain technology ensures data integrity and tamper-proof storage, achieving “inspection of every vehicle, full traceability, automated evidence collection, and real-time upload.”
Staff describe the system as a “tireless electronic enforcement team,” working 24/7, significantly enhancing road supervision efficiency and coverage.
Integration of Multiple Weighing Technologies Ensures Accurate Detection Across All Speeds
The current Off-site overload system widely adopts three main types of dynamic weighing technologies:
·Quartz type (non-deformable): high response frequency, suitable for all speed ranges (low, medium, high).
·Plate type (deformable): stable structure, ideal for low to medium speeds.
·Narrow strip type (deformable): moderate response frequency, suitable for medium to low speeds.
With algorithm models trained on 36 million dynamic weighing data points, system accuracy is stable at JJG907 Level 5, with a maximum upgrade to Level 2, meeting requirements for highways, national and provincial roads, and freight corridors.、
Intelligent Recognition and Big Data Analysis Make Violations “Nowhere to Hide”
The system’s intelligent vehicle recognition module can automatically detect violations such as obscured, damaged, or falsified license plates, while integrating vehicle feature recognition and BeiDou positioning data for “vehicle-to-plate” verification.
High-definition video monitoring not only collects evidence of violations but also intelligently identifies road traffic anomalies, providing dynamic perception data for traffic authorities.
The back-end Visualized Digital Integrated Control Platform, based on GIS maps, IoT, OLAP data analysis, and AI models, allows real-time processing and visualization of the entire road network’s overload data, providing authorities with statistical analysis, traceability, and precise dispatch support.
From “Human Wave Tactics” to “Tech-enabled Supervision,” Enforcement Efficiency Surges
Compared with traditional manual inspections, Off-site overload enforcement systems represent a comprehensive upgrade:
·Enforcement efficiency increased multiple times: automatic detection without manual intervention.
·Reduced safety risks: fewer personnel working at night or in dangerous road sections.
·Wider coverage: technology devices deployed across regions, roads, and nodes.
·Fairer enforcement: complete and reliable evidence chain, minimizing human judgment errors.
After deploying the system in one province, overweight case detection increased by 60%, road structural damage significantly decreased, and road quality continued to improve.
Promoting Industry Compliance and Supporting High-quality Transportation Development
Technology-driven overload control is not just an upgrade in enforcement methods but a transformation in industry governance. Its application helps:
·Curtail overweight transport and reduce road maintenance costs.
·Reduce traffic accidents, protecting lives and property.
·Optimize transport market order, bringing freight rates to reasonable levels.
·Enhance enterprise compliance, lowering operational risks caused by violations.
Many logistics companies report that Off-site enforcement makes industry rules more transparent and controllable, promoting the transport sector toward standardization, digitization, and intelligence.
Technology-driven Overload Control Opens a New Chapter in Intelligent Transportation
With the development of AI, big data, and IoT, Off-site overload enforcement systems will advance toward greater intelligence, connectivity, visualization, and coordination. In the future, the system will play a more important role in traffic safety governance, road planning, and transport dispatch, providing robust technological support for building a safe, efficient, green, and intelligent modern integrated transport system.
Technology-driven overload control is becoming a powerful engine for transportation governance in the new era.
