Nope. Traffic lights create high traffic areas, by unnecessarily delaying cross traffic.

Near my parents house, there is a 6-way intersection. When I was growing up, it was served by traffic lights, with straight and left-turn lanes in all directions. Traffic was backed up all day long in 3 of the 6 directions, to the point that pretty much everyone waited through at least two turns.

A few years after I left home, they converted it to a two-lane roundabout. Traffic immediately died down. Now, you typically see one to two other vehicles when you pass through the intersection, and you never wait more than a few seconds to get through.
