Chicago’s road grid is interrupted at least 250 times for traffic circles:

The Chicago Department of Transportation reports it’s aware of 250 that appear on landscaping lists. The department is currently not clear on the likely sizable number of circles that require no landscaping.

One of the best features of traffic circles is that they force drivers to slow down and pay attention. They cannot blow through a stop sign or traffic light or unmarked intersection. If they can successfully yield and do not need to stop, they can keep their momentum going at a more reasonable speed.

This is an interesting way to count road features: those that need landscaping need to be on some list so that maintenance can be done. Those without the landscaping need would have to be on some other list to be counted. Is this the sort of task AI could do in the future with access to websites with satellite imagery?
