Switzerland based ADEC Technologies, a manufacturer of non-intrusive road traffic detectors has released a new traffic detector, the TDD1-MW75 with an increased range of 75m (250ft). The detector which works on the principle of Doppler shift more than doubles the range of its existing detector model ? the DD1-MW30 which works for short range applications. The TDD1-MW75 is flexible and can be configured for detection of ranges of 30m, 45m and 75m using an infrared remote control. It is specifically designed for green phase request or extension at temporary or permanent traffic lights.
