So, if they make things worse, what do you think their useful purpose is?

Traffic lights can, if used sensibly, alleviate problems at some
interchanges and serve a useful function in ramp metering. They are not
a universal panacea but that is how they have been treated by the lazy
and incompetent.

I find them useful because they make motorists drive in convoys with
gaps between the convoys where people can cross the road without fear
of being killed. The alternative seems to be an endless stream of
traffic which makes crossing the road virtually impossible or else
means waiting a long, long time.
