How we help the customer
In the municipality of Assen, Sustainder and Flitsmeister executed a pilot in which the smart street lighting is optimized based on up-to-date traffic data. This traffic data comes from Flitsmeister-app users who are travelling on the route on that moment. The aim is to use dynamic lighting to improve traffic flow as required, to promote traffic safety and to save energy.
On the Europaweg-Zuid, the light is dimmed or amplified at the moment it is necessary. This means more light when traffic is dense and less light when the road is quiet. Extra light can also be added in case a car stops or during emergency ambulance rides. These applications increase the safety of the people involved in an incident or people having to deal with an ambulance in traffic. The current dimming schedules are further optimised based on the traffic data. A first analysis of traffic data on this stretch shows that an adjustment of the current dimming schedule, adapted to the average traffic density, saves an average 25% in energy use and CO₂ emissions.
