TDC3 Series Cutting-Edge Non-Intrusive Traffic Detectors for Single Lane Traffic Data Acquisition Features   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. Typical Applications ADEC 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 Superior Data Accuracy Speed-Error: < 2.1% / 2.5 km/h (F-B and F-F models) <2.6% / 2.9 km/h (B-B-45 model) Count-Accuracy: >99.5% Classification-Accuracy: 85% - 99.5% Standardized vehicle classification German TLS for 2, 5+1 and 8+1 classes Multi technology detection Three independent physical detection principles Auto calibration Auto calibration within the recommended height above the lane with dedicated software Queue Detection Detection of standing vehicles Detection of wrong-way drivers (WWD) Detection of lane-changing vehicles and vehicles travelling between adjacent lanes (except TDC3-2) Wide operating temperature range (–40 to +70°C (–40 to +158ºF) Optimal performance in all weather and climate conditions 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. Remote configuration and setup With dedicated installation program 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 ADEC Technologies AG ● Gublenstrasse 1 ● CH-8733 Eschenbach
