Not really on topic, but just wanted to chime in regarding the Min Green.

The min green exists for when there's very few vehicles. Do you really want to wait for more than 4 sec (green) + 3 sec (yellow) for a single left-turning car?
Aaahhhh, yes... Makes total sense!

Thanks bruin... but now that you're here, maybe you can briefly touch on whether it is possible to have a circular red on the same signal head that has a green arrow, and maybe elaborate briefly on why that type of set up would be used!
