Dopler Traffic Study Module

We combined years of experience in doppler radars, traffic data analyses and embedded electronics to build most feature-rich and affordable device for traffic data collection.

Highlighting low-profile design, fast and easy field setup, nonintrusive vehicle detection technology, the TDS-300 provides most detailed traffic statistics among all doppler-based devices on the market.

Thanks to the graphical OLED display and four navigation buttons interface allow quick and simple configuration and diagnostics of the unit.

The DTS-300 Doppler Traffic Study Module is capable of collecting traffic data during a virtually unlimited period of time. The statistics include:

  • Individual real-time records with seconds resolution.
  • The Average, Minimal and Maximal speed of each vehicle.
  • Vehicles size / Radar cross section.
  • Speed variation (acceleration/deceleration).
  • Programmable Speed Bins summary.


All information is recorded on removable SD-Card in easy-to-process CSV files compatible with Microsoft Excel. NO additional software required!
