In the context of the article, it would be about any state-controlled roads. Many of those roads would not be limited-access freeways.

Given the stated stated observation that speed limit signs have very little correlation with driver behavior, the only way to significantly impact road speeds is through road design.

That's true. So yes, road design.

I vaguely recall that the US interstate system was generally designed for 150-200 km/hr.
