I went on a trip yesterday and I tried it, it sure didn’t seem to work at all, one person who is stubborn, slow or whatever can mess the whole thing up.
extensively. daily. anyone who picks up their kid at school inevitably has to flow through several. its generally not a problem unless someone isnt paying attention, or just being an ass.
I want to start keeping some bumper magnets in my car for the latter category. Like that guy who tossed them onto shopping cart abandoners. Really gets me grumpy when people just zip in without zippering.
If two cars from one of the queues go through without letting someone in, then the pattern just resumes right after that
In Georgia? 75% chance it works
In Florida? 0% chance of yes
Floridian here confirming that 0%
In Atlanta it’s like a -55% chance it works
florida man: looks down. pulls. “yup. it’s merged.”
Like once, but generally naw.
Yep, Minnesota had some of the best I’ve seen in the US. But it took just one person who didn’t know or didn’t care to jam things up.
Any traffic design that relies on drivers simply “knowing” the unwritten/unposted way of doing things is going to fail. There will always be a new driver, an out of towner, etc, who will react in surprising ways when faced with a new situation.
Not where I am. There’s a huge gap between 90mphers and 45mphers. An absurd amount of people don’t even understand entering a highway at highway speed or exiting one as well as long as the exit ramp is long enough.
Honestly this is one of the few things that have improved in driving over the years. There’s still the occasional douchecanoe who rides in between both lanes to keep anyone from getting by, but that is now the exception as far as I’ve seen.
When 99% of traffic has already formed a single lane then the guy trying to go past a bunch of people and cause an extra unnecessary merge is the asshole and I’m not letting him by.
That used to be my old daily commute. Everyone had already “zipped up” were now in a bumper to bumper column, yet people just fly down the right and then cutoff the whole column to get in. Delaying everyone. Anytime I bring up this “problem” I am told it’s actually not a problem, it’s the way it’s supposed to work, and apparently I am the asshole for complaining about 2 dozen people cutting me off every morning, before I can move past one choke point.
I might be wrong about this, but I think you’re supposed to wait until the last minute to zipper merge. That way, everyone gets the benefit of it.
Idk about any of it. All I know is after they redid the highway and made those two lanes merge at that point, there is now a 10-15 minute backup, when previously traffic in that area was hit or miss. If there is actual traffic it can take almost 30 minutes to go through that one point.
And the trucks are so darn fed up with it that they just block off the end of the lane end now, as they can get caught cutoff by cars for seemingly endless time, they become sitting ducks.
This is correct.
Never. It’s fundamentally flawed.
I’ve never seen a zipper merge work in high traffic, but I have seen “right lane ends” work more-or-less fine. Same effect, but people on the right lane drivers are a bit more likely to yield which makes people in the left lane slightly more likely to make room.
We’re often not a smart species.
I see it all the time I think, but maybe my standards are low. Often what I see the traffic isn’t quite equal in both lanes, so it’s not abab, but people see the guy ahead find a space and they pick a space behind the next car and so on. It’s there more to it? Like if someone doesn’t get it, you just continue the zipper behind them, right?
It doesn’t flow well, it’s more of a stop and start.
I feel like it’s hit-or-miss. A lot of people will zipper merge, but a lot of other people don’t care and mess things up.
I’ve gotten into some very amusing fights online about the difference between merge and yield, some people are just assholes when it comes to driving and refuse to accept they might be doing something wrong.
Yes zipper merging happens, but ultimately in any kind of traffic flow situation it only takes one person to fuck it up. Instead of being reactionary and blaming “bad drivers,” try to take a step back and realize that a transportation system that relies on millions of individual actors, having perfect information and behaving rationally is hopelessly flawed, regardless of the nationality of the drivers.
Yes, I see it happen successfully every day on my way home from work.
In Canada it seems to depend on the city. Calgary is good at zipper merging, Victoria doesn’t seem to know what it is.
Same. I’ve found Minneapolis to be fairly good too, but I only visit occasionally for work.
