Features, Working Principle and Specifications
 

 


Features of the equipment

 

  Non-invasive: Infrared beam detection, no road cutting.

  Multi-purpose: Counts, classifies, measures speed, identifies lanes, and more (red light, heavy vehicle, etc.).

  Precise: Uses overlapping infrared beams and accurate timing.

  Smart: On-board processing with configurable classification.

  Real-time & Logging: Streams and stores data.

Unique features/Measurement capabilities, if any

      Dual IR Beams for Detailed Wheel Analysis: Provides more data than single-beam systems.

      Precise Trajectory Analysis: Can infer wheel width and lateral position.

      Robust Lane Identification: Uses parallel and crossed beams.

      High Accuracy: Reliable counting, classification, and speed measurement in diverse conditions.
