Dynamic cycle path lighting
This video, from the fietsberaad, isn't too clear, but what it shows is quite interesting. It's an experiment with dynamic cycle path lighting. The lights remain at about 20% brightness until a cyclist approaches, when they will increase to full brightness as the cyclist passes, reducing again over several minutes if there are no more cyclists nearby.
The idea is to retain a high level of social safety along cycle paths while also reducing the energy usage and light pollution which would result from full brightness lights at all times.
These experiments do, of course, also use LED lighting to further reduce the energy demand, and they are soon to appear more commonly across the country.
There are further stories about lighting, which include some other experimental schemes.
