In times of increasing traffic density and growing environmental awareness, the collection of data and efficient traffic control in cities are becoming increasingly crucial. One solution that has proven to be highly effective and cost-efficient is smartmicro radar technology.
Thanks to smartmicro sensors, extensive real-time traffic statistics can be generated, providing a precise representation of the current traffic situation. Furthermore, the data can be collected, serving as a valuable foundation for long-term statistics used in the planning of traffic infrastructure and flow. Peak times, variations over weekdays, and seasonal differences can be identified. The statistics generated by smartmicro sensors are extremely detailed, offering insights into various aspects of traffic. These include the number of vehicles, their classification, occupancy of a freely definable detection zone, average speed, and the distance between vehicles.
In addition to comprehensive traffic statistics, smartmicro radar technology allows simultaneous outputs for adaptive traffic light control—all with just one sensor. Compared to traditional induction loops, where a separate loop is needed for each detection zone and lane, a single smartmicro radar sensor can cover up to 12 lanes, regardless of the direction, and up to 32 detection zones.
This innovative technology not only promises significant cost savings but also enables straightforward installation without extensive groundwork. Unlike traditional induction loops, costly construction work is eliminated, as sensors can be easily attached to existing infrastructure, significantly simplifying wiring. Moreover, radar technology is entirely non-invasive, leaving the road surface untouched and significantly extending its lifespan.
Operating costs are minimal, as smartmicro sensors require neither maintenance nor calibration. Regardless of visibility conditions and without regular cleaning, the detection quality of smartmicro sensors remains unaffected, ensuring uninterrupted functionality.
Overall, the implementation of smartmicro radar technology into adaptive traffic light control promises a significantly more efficient use of traffic systems, paving the way for sustainable mobility in our cities.
