@Tropical_Willie that explains the use of a green light not the use of the red one, if traffic is clear when the people on your part of the section is green there should be the option of a turn if there is no oncoming traffic.
@augustlan I do understand that it should be shorter. The one I am referring to has a five sec window on green if roads are slick it is already turning yellow for me the first person in line. If no one is close enough in the turning lane the green arrow won’t turn green until it cycles through eveyone again.
The benefit is that all sides are on motion dectectors. So instead of cycling through the same path everytime it will cycle to the vehicle that arrived next in line. But all the cycles are pretty quick.
I believe this to be unusual, is more frequent light changes more efficient then longer lights? My guess is they can be no longer then 30 seconds but possibly less. This is for the people going straight. The turners I would guess around 5 to 10 seconds.
Again this is not usually a busy intersection. As so I have never noticed pile ups. Maybe a 5 to 6 car one the last few cars may not get through in one go. In the turn lane if cars are idling the 3rd can get if they use the last of yellow to get far enough into the intersection to have to complete the turn.
Could this method be more efficient and I am just more adverse to it because it is different and it messes with my driving style? How would I confirm that?
