I welcome this relatively new signal configuration, as now motorists have the option to go instead of waiting an entire signal cycle to pass before they are allowed to continue. It's a pain; however in major intersections it should be obvious that they have not implemented this system, especially with the 2 left turning lane intersections. The example signal heads shown with 2 left turning lanes yielding to oncoming traffic seems like a bad idea though. It's already dangerous enough while turning when someone cuts you off before you've finished crossing the intersection.
There is a configuration of 2 right turning lanes in my city, where you cannot turn on red, with dedicated signal heads. I've never seen that type of setup done before.
