In the period between 1 October 2013 and 1 August 2014, sixteen streetlights on the Strandstien, Kalundborg, foot and cycle path were fitted with motion sensors which regulate the light so that it suits the actual traffic on the path.
When there are users on the path, there will be light. When there are no users on the path, the lights are reduced to 15 percent of maximum intensity.
The purpose is to examine whether the energy consumption for street lighting can be reduced, particular during the hours between 5 and 8pm, where the load on the electricity grid peaks.
Street lighting is about traffic safety, but also a sense of safety. It is important that the regulation of the light does not impair the users’ experience, and during the test period, this was looked into by interviewing users of the Strandstien path.
Intelligent street lighting makes sense – in relation to both the economy, the climate and the environment. The experiment at Strandstien can provide useful experiences, which, in a larger scale, can lead to significant savings of energy and a larger flexibility in the electricity grid.
