Those are either actual interchanges (like how a highway/motorway interacts with a surface street), or a traffic light controlled intersection. Most protected infrastructure out there do not do either.

I'm not sure what you're saying here. Most of what I've seen called "protected intersections" do include traffic lights. Are you using a different definition?

I was referring to separate traffic light phases for different approaches to the intersection. For instance this protected intersection[1] does not have separate traffic light phases for two same direction approaches. While this intersection[2] does. The first one will have turning conflicts since turning traffic and through traffic is allowed to proceed through the intersection at the same time. The second one will not.

Then also build protected intersections? These are common in truly bike-friendly cities. I see them frequently here in Munich (admittedly not as bike-friendly as Dutch cities, but much better than any US city).
