TDC3 Series

Detectors for Traffic Data Acquisition

TDC3

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 RS 485.

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

FEATURES

  • Multi technology detection

Three independent physical detection principles

  • Standardized vehicle classification
German TLS for 2, 5+1 and 8+1 classes
  • Auto calibration

Auto calibration within the recommended height above the lane with dedicated software

    Detection of lane-changing vehicles and vehicles travelling between adjacent lanes (except TDC3-2)
  • Detection of standing vehicles
  • Detection of wrong-way drivers
  • Wide operating temperature range (–40 to +70°C (–40 to +158ºF)

Optimal performance in all weather and climate conditions

  • Remote configuration and setup

With dedicated installation program

ACCESSORIES

INTERFACE RS 485 E 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

(SOLD SEPARATELY)

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.

MODEL OVERVIEW

  • TDC3-2 (2 Classes)
  • TDC3-3 (2+1 Classes)
  • TDC3-5 (5+1 Classes)
  • TDC3-8 (8+1 Classes)

For available models depending on setup and mounting please consult the installation manual.
