The city of Ghent in Belgium became one big urban laboratory this summer when 16 streets closed down for car traffic. The city residents from these streets were free to decide what they wanted to do with the newly freed up space. Their streets turned into parks, with plenty of playground for children and places to relax and get to know each other for the adults. The experiment, which lasted for 10 weeks, was a success. Neighbors got to know each other better, and people started to realize they didn’t need their cars as much as they thought they would. The organizing committee is thinking about experimenting again soon.
