In most areas, even pedestrianized streets allow delivery and residents' vehicles (sometimes also taxis), at certain times of the day at least. In some cases any vehicle is allowed as long as it watches for pedestrians, and travels at a speed safe for a mixed-use road (meaning 5-20 km/hr or so, depending on road size and congestion). Sometimes the arrangement is called a "living street" if that's the explicit design goal: https://en.wikipedia.org/wiki/Living_street https://en.wikipedia.org/wiki/Living_street In central Copenhagen a number of streets are like that, so you often see delivery vehicles slowly making their way through. But most cars that don't need to drive right into the city center will avoid it and take one of the more major roads that bypasses the city center. So it gets most of the cars out of the city center by just incentivizing them to take a faster route, and allows/requires the remaining ones to share the road on an equal basis with other users.
