Automatic Weigh-in-Motion (WIM) and Dimension Enforcement Systems
The system measures the vehicle's gross weight, axle loads, and axle group loads, determines overall dimensions, and detects violations of established weight and size limits. Built-in video analytics recognizes the license plates of both the vehicle and trailer, classifies the vehicle, and links measurement results with photographs and video recordings.
The system operates 24/7, requires no vehicle stops, and can be integrated with regional and federal information systems.
WHO IT’S FOR
- Road infrastructure owners
- Federal and regional road authorities
- Transport enforcement agencies
- Municipal and regional governments
- Toll road operators
- Bridge and infrastructure owners
- Industrial facilities and logistics centers
Key Capabilities
- Detect overweight and oversized vehicles
- Measure gross vehicle weight and axle loads
- Determine the number of axles and axle spacing
- Measure vehicle length, width, and height
- Recognize vehicle and trailer license plates
- Identify vehicle category, speed, lane, and travel direction
- Capture photo and video evidence for every vehicle passage
- Detect attempts to conceal or obscure license plates
- Maintain a complete archive of measurements and generate analytical reports
- Transmit data to external information systems
Video Analytics
TrafficData’s video analytics detects and tracks a vehicle throughout the entire measurement zone. Computer vision algorithms classify the vehicle, recognise its license plate, generate overview images and link these to the results of weight and dimensions checks.
For each passage, a single digital record is created, containing the measured parameters, recognised number plates, photographs, video footage, speed, lane, direction, location and time of recording.
Anti-Fraud System
The anti-fraud module identifies vehicles whose operators attempt to evade enforcement by concealing or altering the readability of license plates.
If a vehicle’s license plate cannot be recognized or is intentionally obscured while passing through the WIM enforcement point, the system searches neighboring traffic enforcement camera systems for the same vehicle.
Matching is performed using a combination of visual vehicle characteristics, travel direction, and passage time. If the same vehicle is detected by another camera with a visible and readable license plate, the recognized plate number is utomatically associated with the WIM enforcement event.
As a result, concealing a license plate immediately before the enforcement point does not necessarily prevent vehicle identification. Operators receive the matching results together with supporting photo and video evidence.
Operating Principle
-
Vehicle Detection
Road sensors and cameras detect the vehicle as it enters the measurement zone -
Measurement
Weigh-in-motion sensors determine axle loads and gross vehicle weight. Dimension measurement equipment determines the vehicle or vehicle combination’s length, width, and height -
Video Identification
Video analytics classifies the vehicle, recognizes the license plates of both the towing vehicle and trailer, and generates supporting evidence -
Anti-Fraud Verification
If no readable license plate is detected, the system searches neighboring traffic enforcement systems and identifies the vehicle by matching its visual characteristics and movement parameters -
Event Generation
Measurement results and video analytics data are combined into a single vehicle passage record, stored in the archive, and transmitted to the customer’s information systems
Results of implementation
The client gains a tool for continuously monitoring traffic load, detecting overweight and oversized vehicles, performing automatic video recognition, and license plate.
The data collected enables the actual load on the road network to be assessed, road repairs and maintenance to be planned, and the efficiency of traffic control to be improved.
TrafficData provides the selection of equipment, the design, installation and configuration of video analytics configuration, as well as the integration of weight and dimension control points with the client’s information systems.
