The architecture and the German text "Mülihalde" strongly suggest a German-speaking region, likely Switzerland given the tram tracks and the specific style of the buildings. The school warning sign confirms this is a European setting. The overall appearance is very clean and orderly, typical of Swiss towns. I suspect this is in the canton of Zurich or a similar area. I am moderately sure of this location.

The road markings clearly say "SCHULE," confirming a German-speaking area. The tram tracks and the specific architecture of the buildings are highly characteristic of Swiss urban centers. The signage and the overall aesthetic point toward a town like Winterthur or a similar municipality in the canton of Zurich. I am quite confident this is in Switzerland.
