> artificial intelligence and cameras to be able to say "there's no cars come in the opposite direction, I'll turn on the left turn green light and let this car go." You don’t need artificial intelligence or cameras to do that. Inductive loops can detect cars and bicycles and their velocity just fine and control nearby traffic lights, and have been doing that for decades. I would think such local control is less prone to failures, too. Interview with a traffic engineer (IMO one that’s a bit too focused on throughput): https://bicycledutch.wordpress.com/2016/06/21/traffic-lights-in-s-hertogenbosch-an-interview/ https://bicycledutch.wordpress.com/2016/06/21/traffic-lights... Their systems aren’t completely local, given “every bus is tagged and the computer knows all the time-tables of every line. The system knows exactly when which bus needs to arrive at a certain intersection. The installation checks whether a bus is too early, on time, or running late and sets the lights accordingly”
