TDC3 TRAFFIC DETECTORS

Non-Intrusive Traffic Detectors for Single Lane Traffic Data Acquisition

TDC3 TRAFFIC DETECTORS Non-Intrusive Traffic Detectors for Single Lane Traffic Data Acquisition

The TDC3 Series are advanced traffic detectors using Doppler Radar, Ultrasound and Passive Infrared technology.  Comprehensive traffic data including individual vehicle class, speed, length, occupancy time and time gap are provided via RS485.

TYPICAL APPLICATIONS:

TDC3 Series detectors are specifically designed for a variety of Traffic Data Collection and traffic control applications where inductive loops have been used in the past:

  • Vehicle classification
  • Individual vehicle speed
  • Vehicle counting (volume)
  • True presence, queue and wrong-way driver detection
  • Occupancy and headway / time gap measurement

WORKING PRINCIPLE:

TDC3 traffic detectors measure the speed of each vehicle using the Doppler shift of the reflected microwave frequency. The ultrasonic sensor system scans the height profile of the passing vehicle and the PIR zones obtain the vehicle position (except TDC3-2) within the observed lane.

MOUNTING:

Recommended mounting points are gantries or other overhead structures above the lane centre. Clearly superior performance and reliability are a result of:

  • Three independent detection technologies
  • Full temperature compensation across entire temperature range
  • Redundant system functionality

MODEL OVERVIEW:

  • RD_TDC3-2 (2 Classes)
  • RD_TDC3-3 (2+1 Classes)
  • RD_TDC3-5 (5+1 Classes)
  • RD_TDC3-8 (8+1 Classes)

ACCESSORIES:

Interface module USB-IF485 & Software:
For the communication between detectors and a PC during commissioning and maintenance an interface module in combination with the dedicated software is necessary. The interface module and software has to be ordered separately.

Mounting Accessories:
Mounting hardware and cable connectors are not part of the detector delivery unless ordered separately. Information about the available accessories to accommodate various mounting and operation scenarios are made available separately.
