"Best change" is an ambiguous term, but also subjective.
> 4-way traffic management guaranteed to cause a huge traffic jam in the name of health and safety, when cars and drivers (and pedestrians) would better manage the road themselves without any assistance.
This, too, is highly debatable and subjective. Ask a pedestrian trying to cross a busy road if there should be signals, or someone trying to make a left across two or more opposing lanes of traffic.
I think you're blaming the wrong thing. High traffic areas all have something in common, and its not traffic signals: it's traffic jams caused by too many cars trying to squeeze into a too-small channel.
