    Am I the only one deeply irritated that the left going lane has no arrows and no one is indicating left either?
    This intersection really hurts my sense of order!

        Should be visible on the first panel, unless painted totally randomly out of sync to the right-pointing arrows.
        But that would also trigger my sense of order, soooo… :-)

      I don’t think you have to indicate left when it’s the only possible direction you can go

        I don’t think you have to indicate left when it’s the only possible direction you can go

        But with no arrows on the ground, you could also go to the right.

        Had to learn that the hard way some years ago, when a car standing on a arrow-less lane, unexpected by me, also turned left together with myself standing on the left-arrow-lane.
        We then had a crash while merging lanes, and it was determined to be my fault entirely.

        So the comic also triggers a bit of PTSD for me… ;-)

          Sounds like a fucked up intersection if two lanes merge into one during the turn. Usually they will be two lines woth a solid white to indicated not to switch lanes.

            Yes, it is fucked up intersection, although the two lanes don’t merge into one.

            But what you don’t realize there (because of coming out of a slight ditch) is that the target road on the left you are going to, actually has two parallel lanes.

            Didn’t expect that at all, and the hinted broken lines on the ground are practically useless, as they have to connect 8 arriving lanes to all their possible counterparts in a chaotic way on a curved surface.

            So I just headed to the right side of the left road (not realizing I thereby did a implicit change of lanes), while the car to my right was totally unexpectedly overtaking me from behind, starting from the unmarked lane I didn’t suspect to also optionally lead to the left…

            Really fucked up situation for anyone not being local and accustomed to it.

        Maybe the arrows are covered by the cars.

        Not in the first panel.
        If there were arrows, they should be visible in parallel to the arrows going to the right.

        Why would it be a left-only lane?
        There are no arrows on the lane…

        And even if it was, you still have to indicate your desired direction, as the direction of the lane might not be clear to all traffic participants.

            Why would turning right be illegal?
            As far as we can see, it is a lane with no mandatory direction (which is the thing that has been bugging me in the first place).

            But, TBF, I believed that myself for a long time, only to have the called police give me a little crash course in traffic lane rules after I had a car crash in a somewhat similar situation…

        Can you summarize the gist of it? I keep seeing this claim and it is extremely non-intuitive.

        Supposing it’s true, how is it we’ve magically arrived at the optimal number of lanes as of the uttering of the statement?

        If it’s a basically linear function where the lowest traffic is near-zero lanes, is there an implication that mass transit would be built in tandem with lane reduction, or does everyone just get more miserable?

        Edit: I’ll add that what I’ve heard is that more people choose to drive until the misery-equilibrium is reached. So roads will always be as busy as they are now because they are at their max tolerable level of drivability. That seems plausible for some roads and for some finite number of lanes, but not generally applicable.

          Essentially you need all streets to be serviceable by trucks, ambulances, etc., and therefore the general minimum is 1 lane. As you add car infrastructure, it becomes relatively more convenient to drive to a destination than take other modes of transport. You are also typically investing in the car infrastructure at the expense of alternatives, a straight opportunity cost and a sort of spiralling trap, as development becomes more and more centred around the car.

          Braess’s paradox outlines adding a route can actually worsen overall network flow, and more broadly, new capacity just attracts new drivers until congestion returns to roughly where it started. Suboptimalities like the accordion effect are compounded as more traffic is added to the system.

          Induced demand doesn’t imply the current number of lanes is optimal, just that expansion tends to be self-defeating.

          Lane reduction alone would just increase misery, so the answer is redirect road space into transit, which absorbs displaced drivers at higher capacity. Otherwise it’s just misery.

          I have a civil engineering degree with a focus on transport but never really used it for that, so this is something that I was taught, but had over a decade to devolve more into opinion.

        So close. The first car is too close to the line.

        I drive to patients homes all day and I daily see people in the suburbs stop far enough back that they don’t always trip the left turn arrow, sometimes leaving that lane stuck an extra cycle. It would be infuriating, except that my drive time is paid and mileage reimbursed, so I’ve chosen not to let it bother me. I just roll my eyes and wait.

          Generally when approaching a intersection on a red light you should stop the car so that you see the white line at the top of your hood. This allows you to also see the painted crosswalk and any pedestrians in the crosswalk (no matter their height) when sitting in your car.

          If it’s a two lane or more roadway it also has the added benefit of letting the driver to your right see pedestrians more clearly if they are making a right turn.

          The person in the car furthest right can now pull up and have their wheels touch the white line (if turning right) and not have to block a crosswalk, while having a full unobstructed view of the intersection to the left, it also allows a pedestrian crossing to see the car in the far right line as they approach the end of the intersection.

            At least here in Austria we often have left turning lanes, that have a magnetic sensor/loop in the street and the traffic light only switches, when you’re on top off it.
            People stopping way too early and especially people leaving too much space between cars is really infuriating in the city…

              Those sensors are the apex of Modernist arrogance, where people just decide they know every detail about any system they look at and can control everything.

              There is no single place where they work. But at least people have been steadily removing them for the last 30 years.

                I’m not really sure, if I understood you

                In streets with high traffic, the left turning red light only goes to green, if someone is actually there waiting. Because else it would make a longer red phase for the opposite drivers going straight

                So, it seems like an improvement to me

                What am I missing?

                  Every traffic situation where people would need to cross but there won’t be a car stopper exactly over the sensor.

                  Not exhaustively:

                  • motorcycles

    I was at a traffic light with my support worker a few weeks ago, and this dumb fuck wasn’t on the sensor. He was sitting there for like ten minutes and wouldn’t move forward. My sw got out of that lane and went a different way. When we came back a couple mins later he was still there!

        In theory, it’s an efficiency measure.

        If there is a main road with higher volume, various side roads and no other bottleneck down the road that needs to be accounted for, it doesn’t make much sense to regularly interrupt main road traffic if nobody else needs the intersection. Conversely, depending on the interval, the side road drivers may have to wait a long while if they just barely missed a green.

        Both of these cause traffic risk as well: Firstly that the main road driver who decides the red light is stupid and cuts off a side road driver they didn’t see, secondly that a side road driver who barely missed green doesn’t want to wait and tried to squeeze in before main road traffic picks back up.

        Having the traffic lights switch on demand reduced those risks: Main road drivers who know that it’s red only if there’s gonna be some other car may be less reckless in running it, while side road drivers don’t have to wait as long and don’t feel the need to squeeze in.

        Of course, it can’t ever remove the risks entirely because humans are what they are. It also depends on people actually driving up to the point where the sensor detects them. If they don’t know about the concept, they’ll have a hard time understanding what’s wrong. I was taught those things in driving school, but if it’s not a thing in your area or wasn’t when you learned, chances are nobody told you about it later.

        I live in big city that has unpredictable traffic and construction everyday, where a 10 minute difference in departure time can exponentially increase your travel time. I have at least 3 primary routes to get home, and navigation helps me choose the best route at the time I leave. It will also suggest detours if it finds a faster way enroute.

    Canada, in a single image? I’ve driven cars in most European countries, Canada, US (small amount), Mexico.

    Canada has the worst road designs of them all, though since almost everything here is modelled after the US, I guess it could still be worse there

    I regularly see road situations where I can only wonder how high they were, what they were smoking, and where I can get some

    Intersections where only one lane has traffic lights, the other doesn’t. How are you supposed to cross that? Simple: you throw a hail Mary, close your eyes, andale a run for it while praying to some non-exist God. This is howy stepson got sideswiped, by a guy having to do exactly that.

    Making a left turn in Canada? Great, you got green! Go? Well no, cars are still coming from the other side, they inexplicably got green too so now the intersection with traffic lights also acts as an intersection without traffic lights. Amazing designs!

    But wait, there is more!

    Once those cars from the other side are gone, you might be tempted to think that you can now just drive, but noooooooh, this is Canada! Pedestrians also got green so now you need to try and avoid those too if you can. The amount of near misses that I’ve had and that I’ve seen with others is staggering, crossing roads in Canada is fucking dangerous.

    All this adds up to that going left basically means that you get green light and you can’t do shit until it gets orange, then you quickly squeeze yourself through and pray that you didn’t murder a school class by accident.

    This, in turn, means that going to the left is an exercise in patience, because each green red cycle, about one car will be able to go to the left. If each cycle takes a minute, and you have ten cars in front of you, that means you’ll have to wait ten minutes I shit you not.

    Compare that to the Netherlands, where intersections get redesigned and rebuilt every time when anyone sees there are tooany accidents, and there are soany amazing traffic flow control designs there. Here in canada, traffic flow designs is “road, done”

    I love Canada, I feel proudly Canadian, but Canadian road designs are removed as fuck.
