First of all, will do my best to keep the formating, but forgive me if there are issues.
Not so sure. At the very least, drivers would have to associate a light pretty far away with their movement while choosing a proper road at the same time.
They're using large overhead signs, a rarity in PEI. It'll be pretty obvious guidance.
To make things worse, there will be multiple lights within a field of view at the same time.
It's in an urban environment so that's not a factor.
Let me put it so: signage, which is essencial for complex layout, is not shown in video - and I can easily believe it will be lacking in real life as well.
The signage is indeed shown in the videos. Maybe not on the CTV site, but certainly going to the primary source the ones there do show overhead signage:
https://www.princeedwardisland.ca/en/information/transportation-infrastructure-and-energy/displaced-left-turn-intersectionAs simple as that - no stop line for TCH traffic on an X in headline image with traffic light on a backside of an intersection. How many drivers will be blocking X, given they need to stop pretty far back? I drive through an intersection with somewhat similar problem - so my anwer is "a lot"..
Legally there would have to be a stop bar there, so it would be required for reality but immaterial for the animation. I'm more inclined to believe that the animators missed it than the engineers did.
Curb radius is likely of litle help here, it is not seen. Signage - especially pavement - wearout is also an issue. As far as I understand, this is a largely tourist spot, so many new drivers at any time; complex solution which commuters eventually get used to is a different story.
Design features like curb radii are deliberate features that subconsciously alert drivers. For example, try making a right turn at an intersection with a channelized right, but at the intersection itself, not via the channel. You'll be very aware very quickly that's not something you should do. It's not the be all and end all, but that's what signage is for.
Signage wear is an issue on literally every road. But that's why maintenance crews exist. Furthermore, the issue of a wrong way move here would only impact the left turn collector lanes, not any high speed mainline. Meanwhile freeway offramps also just have signs and sometimes pavement markings to indicate that's the wrong way - and the consequences of a wrong way move on a freeway can be catastrophic.
Scale of the job seen on a google map easily warrant multimillion project bill anyway.
And I don't fully agree with "same as any other traffic light" asessment. This is a dense cluster of light, with most movements seing 2 lights - and slowing down more than for a single one.
Drivers will encounter one signal at a time and will treat them as such. They just will consider what they have to do at that moment, "where am I going, do I have a green or red, etc". It's the same as any cluster of signals in an urban environment.

This project came in a $5.3 million for the reconstruction. So half of what a structure would have cost, to say nothing about the ramps, signals the ramp terminals, expropriation of properties, and construction staging.
For a comparable project to that, Highway 6 at Laird Road in Guelph, ON, came in at $15.5M in 2011 (almost $18M today). Though it required far less property than this project would.
And I don't fully agree with "same as any other traffic light" asessment.
Based on the statement that the "entire system goes totally toast without power, or with controller glitch", that is true of any signalized intersection. Once the power goes off, the traffic control ceases to work.

Yes, you will encounter two signalized intersections in quick succession. But again, that's absolutely no different than what one would encounter ion an urban environment.
The article suggests it's the first such intersection anywhere in Canada, so it's perhaps understandable why the source describes it that way (much as how the US media tend to think nothing outside the USA counts).
First purpose-built one. The intersection of Bathurst, Lakeshore, and Fleet in Toronto has evolved into this sort of design for the EB-NB movement, but not quite the same.
