Streetlights in parking lots are major contributors to energy waste and light pollution, especially if they burn all night when there is no one in the surroundings.
Located on the outskirts of Groningen, the Park+Ride (P+R) transit hub is a large outdoor parking lot, used by thousands of people daily. Commuters park their cars here before they switch to public transport to continue their journey. Approximately 10% of the cars stay at the P+R throughout the night. The area relies on more than 100 lamps that burn bright during the dark hours.
