12-8-8 Eagle Flatback With Advanced Green

Here's a Eagle 12-8-8 flatback mounted on a truss arm, this one has the the old flashing green interval and also has the harder to find "Advanced Green When Flashing" sign attached to the mast arm. Oddly the ones in this intersection flashed at a slower rate than standard since this one flashes at the same rate as the ped signals, regular flashing greens flashed 2.5 times faster than peds.

The flashing green here was used to indicate a protected left and through phase here in Ontario and is also known as a "Advanced Green". They're being phased out here with steady green arrows because of concerns that visitors unfamiliar with it are confused by this signal but you can still find these in use at some small intersections.

Here's a short video showing the flashing green ball in action:


The sequence is Red -> Flashing Green -> Steady Green -> Amber -> Red
and for the opposing side Red -> one sec after the other side has a steady green -> Steady Green -> Amber -> Red

Some municipalities decided to combine the idea of a flashing green ball with the green arrow and use a flashing green arrow to indicate a protected left turn.

My controller has an option to flash the green output at 150 flashes per minute. The standard flash rate is 60 flashes per minute.

Interesting can your controller do flashing left turn arrows too? Some places in Ontario flash their left turn arrows.
basilicon89   [Sep 18, 2011 at 07:09 PM]
flashing yellow arrow?
joe_347V   [Sep 18, 2011 at 07:11 PM]
Oh I meant flashing green arrows, they flash the green arrows at 150 FPM then switches to a steady yellow arrow before going to the green ball.
basilicon89   [Sep 18, 2011 at 07:13 PM]
Yes you can use that feature to do that. You can turn on and off flashing green with a time of day event. My controller does flashing yellow arrows too, as I have one in my basement intersection

Update: the pair of signals in the video has been replaced and a temp spanwire setup installed in their place. The new heads are 12-12-12-12 Fortrans with a left turn arrow.

Added a video of a flashing green signal in action.

Hmm. I've never seen a flashing green arrow or ball before. Only flashing red and yellow. Those greens flash really fast too. Shocked Here it's around 60FPM for a flashing yellow or red for becons or out of service signals.

Yeah, I think the flashing green ball was mainly a Ontario and Quebec thing. They're slowly getting phased out here though, I only know of a handful of intersections here that still has a flashing green ball.

I believe the flashing green arrows are only used in Waterloo region though, the sequence is the same as your typical left turn arrow but they flashed the green arrow indication at the same speed as the flashing green in the video.
