TDC3 Series   

The TDC3 Series is a family of advanced traffic detectors using Doppler radar, ultrasound and passive infrared. Comprehensive traffic data for each passed vehicle, including individual vehicle class, speed, length, occupancy time and time gap, are provided via RS485. Designed for traffic management applications, TDC3 detectors can replace various existing overhead detectors, including ASIM TT29x Tri-Tech detectors.

TDC3 traffic detectors measure the speed of each vehicle using the Doppler shift of the reflected microwaves. The ultrasonic sensor system scans the height profile of each passing vehicle and the PIR zones are used for auxiliary purposes (TDC3-2) and to obtain the vehicle position (except TDC3-2) within the observed lane.

 

  • Multi-technology detection
    Three independent physical detection principles
  • Standardized vehicle classification
    German TLS for 2, 2+1, 5+1 and 8+1 classes
  • Auto calibration
    Auto calibration within recommended mounting height above the lane with ADEC DET-Soft software
  • Detection of lane-changing vehicles and vehicles traveling between adjacent lanes (except TDC3-2)
  • Detection of standing vehicles / queues
  • 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 ADEC DET-Soft installation software

ADEC TDC3 Series detectors are specifically designed for a variety of traffic data collection and traffic management applications where inductive loops have been used in the past and data accuracy is vital:

  • Adjustable maximum speed systems on highways
  • Automated, temporary break-down lane use for increased highway capacity
  • Measurement of vehicles by class and volume for environmental noise and pollution analysis (often in conjunction with other environmental sensors)
  • Establishment of road usage patterns by vehicle class etc.
  • Typical 'your travel time is' systems
