Intersection design:
- Ave Jules-Verne is the main road.
- Mikes is the side street.
- This is a T intersection.
- There is only a pedestrian crosswalk to cross the side street.
- Except for the northbound approach (which has a dedicated left turn lane), there are no dedicated turn lanes at this intersection.
Signal timing:
- Mikes (the eastbound approach) has a green ball, with a right turn overlap for the southbound approach.
- For the main road (Ave Jules-Verne):
1. First, the signals display a solid permissive green ball for north/south traffic.
2. Next, the signals display a flashing green ball for northbound only, while southbound has a red light. The side street (Mikes), has a right turn overlap.
3. Then, the signals display a lagging through arrow for northbound and southbound, with the pedestrian phase to cross the side street. The pedestrian phase only activates with the through arrow. Drivers must not attempt to make a turn during the through only arrow, and they must treat it like a fully protected turn signal red arrow.
- Each yellow interval is 4 seconds.
- There are no all red intervals at this intersection.
- Right turns are permitted on red after stopping.
Trivia:
- As part of Quebec City's bylaws, pedestrian phases must not be permissive. All pedestrian phases must be fully protected (fully protected turn signal separation, through only arrows, all way fully protected pedestrian phases, etc),
- As part of Quebec City's standards, all red intervals must be avoided, except if it takes more than the yellow interval time to enter and exit the intersection traveling at the posted speed limit.
I find the signal timing here very interesting and unique, especially that the left turn priority activates the middle of the cycle for the main road (Ave Jules-Verne), and how pedestrians are fully protected from turning traffic by a through only arrow!
I’ve never seen this kind of phasing before! Definitely gets your attention!
So at the end of the flashing green phase, you’re being shown a pedestrian protected overlap and pedestrian recycle is set to on.
If you push the button too late, sometimes the overlap will still terminate and try to cycle but it will just clear right away because there isn’t enough max time left in that phase.
The through arrow is using some kind of logic to run just the arrow rather than the ball.
I love this intersection and the phasing! I personally think it would make more sense to either add a thru arrow to the vertical signal for it to activate during the ped phase, or possibly have it red while the Gentrols perform the thru arrow! That "glitch" at the end looks very strange, I don't remember seeing that!
I agree with adding an arrow on the vertical signal so you’re not faced with a dark signal.
As an American, Québec traffic lights look absolutely ridiculous
All of those flash rates are weird. The ped clear is not 50% or even, or the right speed hahaha
Nice... Except it takes a million years to just turn on the crosswalk light. Ive never seen such a long phase before a green for pedestrians. (Im not gonna call it white. Its green in my country. Idc.)
We even call it green in the US (we're not going to tell our kids to wait for the "white man" to cross the street)
@@frafraplanner9277 On the other hand, we do have white flashing light on railroad crossings to tell you it is safe to cross. 😅
