Most pedestrian areas I know (and I've lived in some) are also accessible to at least light cargo trucks. I've also seen semi trucks in larger streets, and (large) cargo bikes in narrow ones. In my experience, shops and businesses tend to get deliveries early in the morning, when the streets are nearly empty. On the contrary, delivery vehicles tend to get exempted from "anti-car" rules, or regulated to some designated time slots.
