@anon_opin@mastodon.social In Chester, the Fountains roundabout on the ring road was traffic light controlled for many years. The council ran an experiment to turn the lights off and see if the traffic flowed better without them. The improvement was amazing, and the lights have now been removed. Fair play to the council for actually trying the experiment and following through. It makes you wonder how many other sets of lights are causing more harm than good.
