The DSD radar speed display is the ultimate speed reduction tool. In addition to displaying a vehicle’s current speed in green (provided it is below the programmed maximum speed) or in red (if exceeding the speed limit), it also shows the driver a smiling or frowning face. This feedback system was invented by DataCollect and ensures high acceptance rates among drivers. The DSD is the original! It has modern sensor technology that can record speeds starting at km/h so it can be used even in pedestrian zones. Even better: the non-breakable, lightweight device can be installed by a single person in only minutes.

The DSD flex can be used as a speed display sign, a message board display or a combined speed and message board display. During heavy traffic volumes the speed including behavioural feedback can be displayed, e.g. a smiley or sad face. During low-traffic volumes the display can become a compact message board/information sign. Local events can be advertised or road warnings concerning accidents or adverse weather conditions can be broadcast. Regardless of the mode in which the DSD flex is operated, traffic data is always recorded bidirectionally to give accurate speed and volume data.
