1What does it cost?
It saves more than it costs :-)
2How much energy does it save?
It saves up to 80% energy, depending on volume of traffic.Currently, on-road tests are running.
3Will pedestrians be recognized?
Practicaly, cars, bicycles, pedestrians. The object recognition can also recognize animals and movement profiles.
4Is every single latern dimmed, and how do the laterns communicate? Are extra cables to be installed?
The system provides control of every single latern, segment or whole street of houses. The sensor technology and control is provided forward-looking, so that road users will not recognize the dimming at all. The communication is done wireless.
5Can existing laterns be equipped with this system?
Yes. Laterns with integrated dimmers can be equipped very easily. Only tho additional fittings for the sensors at the entries of the street of houses have to be installed. In this case, the street of houses will be controlled as a segment. Laterns without dimmers have to be modified.
6Isn't it annoying when the light is dimmed up and down permanently in the night?
Usually, modern laterns provide a close delimited luster cone scattering very low light into living quarters. Therefore, the street lighting does not differ much from the light of passing vehicles. For settlements, an off-period until, say 12:00 pm, can be set. Not till then, the dimming system is activated.
7Is this system sustainable?
Of course! Extensions are in the area of Smart City, like 5G networks, traffic management, car-park routing, warning systems, signage.
