TDC3X-T Multiradar™

Maintenance-Free Tunnel-Traffic Detection

The TDC3X‑T Series (click here to view the promo-video) comprises advanced, non‑intrusive traffic detectors equipped with multiple independent radar sensors, each capturing a high number of measurements per passing vehicle to ensure precise per‑vehicle data acquisition. Based on these detailed radar measurements, the detectors provide comprehensive traffic parameters including vehicle class, speed, length, occupancy time, and time gap.

Designed for maintenance‑free operation, the TDC3X‑T features a compact enclosure with IP66/67 ingress protection for reliable use in demanding tunnel environments.
The TDC3X‑T series is protocol‑compatible with both the TDC3 family and the Xtralis/ASIM TT29X series, ensuring smooth integration into existing infrastructure.

Applications

TDC3X‑T detectors are designed for traffic data collection and traffic control in tunnel environments, especially where inductive loops or cameras are impractical. Typical applications include:

  • Individual vehicle speed measurement
  • Individual vehicle length measurement
  • Vehicle classification (by length or height profile)
  • Occlusion-free vehicle counting / volume
  • True presence, queue detection and wrong-way driver detection
  • Occupancy and headway / time gap measurement
