I'm sure AI can figure this out better than a human can. Obvious and empirical, we certainly haven't figured it out or optimized it, with all the engineers that CalTrans has. How often have we been in a four-way controlled intersection and the green is on for the empty side. There's no way that's impedance matching, it's more like Good to go boss, call it a day. There's no incentive to modernize traffic light control because it's public works and there's no capital profit motive for it in the same extent as private. I would not advocate privatizing it either because that will bring different consequences. The hero will be that new young Caltrans engineer who's grown up in the AI generation and will probably be fed up with the legacy technology.
