As this short left out most relevant information, I've looked it up for anybody interested: It saves cost because refitting trains is expensive due to down time but adding a sticker is fast. Secondly there's only one camera array per platform and it tracks the QR codes to check whether the train is moving, doors are open or closed. So in total you only have costs per platform and almost none per train
Thank you. I watched the video multiple times and I couldn't understand what she was trying to say. She left out what the expensive machines did, that the QR codes replace.
@ehmzed The initially planned system was supposed to wirelessly communicate with the platform doors, which means it would have been needed to be installed on every single train resulting in a lot of downtime.
@@primarina video can detect qr codes, when the train arrives, the camera will read the qr code - door is closed. If they can't, door is open, and can safely open the safety doors as well.
When the creator of QR code invented it, he made the pattern free so anyone can use it. The company monetize the product by selling QR code reading devices. Now your typical phone can read it so it's basically a free invention that any and everyone can use
It was suggested that the additional barriers were the added expense and I don’t get how having stickers with QR codes serve any purpose where there are no additional barriers.
@@travelwell6049 The additional doors in metro stations require some signal to open only when the train arrives. Initially it was done by having sensors on each train which would signal the gates to open. It is expensive on it's own and requires modifying trains, which takes time. Now the gaits remain, but they are opened when the cameras read the qr code on the doors. Which means the only modification to the train is attaching qr codes on the doors. With that cost is significantly lower, which allows to install those gates on every station
@@travelwell6049 It's about the sensors. Each train would have to be fit with expensive sensors to make sure the barriers close and open on time. But instead they now use QR codes which is just a sticker so it's wayyyy less expensive and instead of putting sensors on every train, you just put cameras in the platform (if they don't have it already). Hope that makes sense.
@@travelwell6049 what was left out of this video is that they need to synchronize the train doors and the platform doors, which originally was going to require adding expensive equipment into every train to communicate with the platform.

Why do you even need safety doors? Unless you live in NYC, where random idiots pushes you onto the tracks. ALWAYS BE mindful of your surroundings. Trust no one. I always stay far away from the tracks when I'm in Europe & Asia. Same for standing on the sidewalk anywhere. Stay far away from the road, so no one could just push you onto the road.
QR codes actually do save lives. I work as a software developer for a pathology lab that rolls its own custom lab information system, and we use QR codes on just about everything to prevent things from getting mixed up between patients. A mixed up specimen or slide or whatever could mean the difference between getting diagnosed with cancer or not, so it’s pretty important that they never ever get mixed up.
@ These are little glass slides we’re talking about. A QR code is way more information dense than a regular 2D barcode, and they even have error correction. Also the extra room reclaimed by not having a big ass barcode across the whole label allows us to put other information on there
This is only implemented on 1 line namely Asakusa line, and the main reason for it is that Asakusa line has through services from other lines operated by 5 companies in total. Generally trains use sensors to operate platform doors, but given that 5 companies operate, it would be a nightmare cost to make all of them compatible. Additionally, some companies operate 2 door cars instead of 3, or have different car lengths. Hence the QR code scanner is a cost efficient implementation, removing compatibility issues by sticking the codes on certain doors of every trainset, giving the system the precise information it needs
yeah every time ive used a qr code somewhere ive been spammed for months afterwards with phishing attempts. people need to stop pushing them on everything.
i think i understand what you’re saying lol but i think it’s worth mentioning that children or people with physical disabilities also can fall in purely on accident! subways move incredibly too fast to not use any kind of safety measures that are available :)
pretty much what our police do. cant control bad guys who break laws so they make new laws to outlaw legal things so innocent people can be prosecuted and they can pretend theyre doing something useful.
that`s a good queston. my phone some times can`t read projected qr codes like on another device, because it`s to crowded with fragment`s of the LEDs of the device it showes the qr code
No, that are not typical QR codes, That are positional markers that are used to define a 3D position with 2D cameras. The distance, skew size of the patterns can be analyzed to determine where the object is and how it moves. If the position and movement doesnt make sense, the system will not do anything. You could try and match those though.
Poor shiny trains from people 😂😂😂😂 You know it's really hard to travel in normal trains because people take your paid seat and act like they paid for that shit 💀
The traditional barcode is morse code in line form. Being based just on the alphabet only allows so many configurations, the QR code is like the 3d chess of barcodes
In addition to the video, Since Keikyu, Asakusa and Keisei lines corporate to make it accessible and convenient by sharing their line, the QR code is attached to one of those trains to identify the number of doors in each car, and help platform door open in right place. Because some of the trains have only two doors in every car not 3 or 4. Thx for the system. It really helps station stuff to do it without operating on their own like what it used to. 😂😂😂

I hope these come to New York because of all the subway attacks i hear about. I would be too afraid to visit anywhere with a subway without safety doors like this
People talk about Henry Ford, but lots of industries including the car industry all adopted how Toyota organized their way of working. Side Note: Often they fail at implementing it correctly. 1 example is just in time delivery, during the pandemic delivery problems happened and companies ran out of parts needed for their production processes, because they didn't have an inventory. Toyota did, because Toyota actually said: keep as much inventory as you need, no more and no less. Lots of companies though: we can keep even less, it saves money.... no, you have to have as much as you need.
Just a quick geek moment. QR stands for "quick response". And it was meant to replace the one dimensional bar code with a two dimensional system. It also worked with Japan's Kanji alphabet. It's been adopted universally for its data capacity and error correction.
Safety doors are basic level standard in South Korea and China. In Japan a lot of stops don't have safety doors, I was surprised they are quite far behind in these safety investments.
I don't know how the technology works, but here in Hong Kong there is a seperate organisation (MTR) that arranges and controls most things for the train system. They have full floor to ceiling doors that automatically open and close, and I never really knew about the concept of not having any type of gate between the tracks and the platform until I visited New York!
Not really, she's not *exactly* right in how she's saying it. The expensive machine in this case she's talking about is basically train automation. In most of the world, in order to have platform screen doors, the trains need to be automated so they stop consistently in the same place every time and line up with the doors. The automation is expensive, but it also allows you to run trains closer together and thus move WAY more people per hour. Japan kind of cobbled together a unique solution, but are reaching the point of capacity where they *have* to automate the trains in order to continue to scale the system. So like, it was a really clever solution but will likely be replaced now that Japan has started to test train automation as of like 2 years ago.
It's less of a Single machine and actually a very complicated system of Signaling and interlocking devices called ATC (Automatic Train Control) which essentially means that Train being run Automatically, it's a technology that is sometimes installed on its own, for Example the PATCO speedline in Philadelphia was the first to use it, with BART, WMATA and the Vancouver Skytrain all being Early Adopters
Idk why countries dont do like qatar, here in metro stations they are fully closed like not halfway like in the video, no FULLY closed like a normal big wall with doors and it opens somehow, i think when the train makes a special noise the doors opens. You can search them up to understand
solution: cameras and have them scan a personal id code to even get inside, then fine them the total cost of running the entire subwaysystem for 24 hours, give them 48 hours to pay off the fine in ite entierity or face jailtime equal to 1 year for every 1000 dollars not paid.
@@theldraspneumonoultramicro405 You dont have to get in the train to spray over or scratch off the QR code. The sprayer sneak into the depot were the trains are parked to vandalize them, not in the trainstation.
I think the expensive machine is the safety door, no? I mean there are tons of ways to make sure that the doors are aligned like infrared, lasers, sensors etc. and I doubt that their cost hardly matters compared to installing a bunch of mechanical doors at a station
No actually their original plan was to install a system/machine on each train car that can be synced with these doors at the station, which would've cost at least $15,000 PER TRAIN. So the guy who came up with this idea of using QR code is said to have saved 10 million USD. His name is Seiji Okamoto.
this is interesting. in my city (st. petersburg, russia) closed type stations have been in use since the 60s. it's a station where the tunnel is walled off and the station has its own set of doors which have to sync up with the trains. what they used was just a simple small lamp on the side of the train, which lights up when the train is not in motion and activates a light indicator on the inside of the station wall. simple and effective, no modern technology needed. but yeah, installing lamps onto every train would be more costly than just slapping on a sticker, i guess
@tpjmjmtwdamx2 that just sounds like a scam. Any engineer will tell you you don't need am adjustment that extensive. Easiest way I can think off is a simple distance detecor that look for something closer than the wall and further away than the train doors. Use 2 or 3 as a safety measure
Maybe they meant the system, which allows train to stop at the spot where train doors will be alligned to the gates? But the video truly lacks some further explanation
Good improvement. Personally, every time I get on the Vancouver Skytrain, I'm flabbergasted that there are doors on the train and not on the platform. Imagine a high rise building with doors on the elevator car but no doors on each floor. That's basically how our trains are set up. It's madness.
"Japan has a lot of accidents relating to people falling into the train tracks regardless of if it's intentionally or not ...". Accidents do happen, especially during rushing hours when multiple people are pushing against one another.
Maybe whatever centralised automatic door safety system linked to detecting the train arriving has some expensive physical component or licensing and maintenance fee, and just sticking QR codes on doors for cameras is a much cheaper implementation.
The issue was that many stations, even the same platform of one station, are quite often operated by different operators (through service of regional commuters into and through the Tokyo Metro system, for example). The different operators had different rolling stock with varying door counts, and the expense of building a proprietary system to signal what train was coming and which doors to open was too much to be viable. QR codes made this process wayyyy cheaper by not requiring a proprietary system to be invented. Now cameras can scan as the train comes in and send a signal instructing which doors to open.
Japan is a rich country, and many Japanese people are very respectful. They always follow the rules. Starting at the age of two, children in school don't focus solely on academics; instead, they are taught to be polite, respect their families, and follow the law. By the time they turn three years old, they already understand the basic rules of life. Wow!
yep and theyve been utterly compromised since day 1. every single time ive used a QR its been followed up with email spam telling me crap like i have a parcel waiting.
I am from India amd I would like to thank The Japanese for creating this wonderful invention the QR code. Here in India our metro rail system too have a security door attached to lots of metro stations. When a metro rail arrives, it opens automatically. We have lots of financial transaction system called UPI possible because of QR codes.
Is it not normal to say it like that? its quite normal where i'm from to refer to groups like that especially in history class. I rarely hear Europeon people, always "The Europeans" did this and that etc,
I was wondering why some many stations have recently installed those safety doors. In the past, I never saw them in Japan. I think I first saw them in Singapore.
They're decently tall, enough to reach heart or clavicle height for most people. The added physical effort to climb and the knowledge you'll have to make a bigger commotion can very well serve as deterrents and also give others waiting on the platform more chance to react and pull you back
I hope we implement this system in Vancouver eventually. Quite a few sad stories of people vaulting themselves into the tracks. Not many people die from this due to the breaking system of the train. I still would like more of a barrier to prevent accidents.
In Toulouse, South of France, there's this kind of machinery since the construction of the underground. But it doesn't use any kind of qr code. And it's completely closed so it's impossible to even fall over the barrier
Elizabeth line has the safest doors from Paddington and further, the jubilee line also has it.The doors cover the whole platform from top to bottom so it's more safer
In France there are these subway trains that run on their own(driverless) and there's only a sensor based system in which if the train is in the correct position in front => both doors open simultaneously. In Germany, they created like a tunnel system so that there is no gap between the train and the platform.
The wide platform doors with QR codes were made like that because the line that runs through those platforms have trains with different door layouts, which is what the QR code - most railway lines which use platform doors only run types of trains with the same layout of doors (e.g. the Elizabeth Line in London) so don't have this issue Many stations on legacy infrastructure rail lines also can't have platform doors installed because the platforms are curved, there are some cases where curved platforms have doors (e.g. Tottenham Court Road on the elizabeth line) but the curve has to be very shallow for it to work
How to know someones a boomer, without them telling you: Comments like this. A QR Code i literally just a 2 dimensional Barcode. So it can store a lot more information than a normal Barcode. Thats it.
Because every R-type subway car is different in some way, R46’s and R68/A’s are longer than R160’s. R62/A’s have different door placement than the R142/A’s so trying to put gates is really hard and can only be done on the Flushing, Canarsie, And Queens Boulevard lines right now since each line only uses 1 car type.
What you failed to mention is that this only exists on the Toei Asakusa Line system (including Keikyu and Keisei) due to numerous train types running through service with each other. Keikyu also has a 2-door train (2100 series) that would run into the subway as well (specifically Sengakuji on regular service) and it does not open the middle door per car that other trains have. The other system also has the QR code for doors is a station on the Odakyu line which is only a prototype
Me neither. It makes no sense at all compared to a single sensor. However, it is useful if the trains aren't all the same length, which I think is a better explanation.
In the case of this line, because the number of cars and the position of the doors differ depending on each train, it used to be necessary to install a special device on the train to send a special signal to the platform door, but now a camera and QR code can replace this device, eliminating the need for work on the train and making it possible to install platform doors quickly and cheap.
@mdgw7 i know the the chip which sent the signal is very small and cheap. The signal is very simple to transmit information about train information. Those chips are small and are much cheaper than installing many cameras overheads as in the video.
These days , QR code is used really widespreadly extensively. But i didnt know it was invented by japanese ! Really well done..

Side Note: Often they fail at implementing it correctly. 1 example is just in time delivery, during the pandemic delivery problems happened and companies ran out of parts needed for their production processes, because they didn't have an inventory. Toyota did, because Toyota actually said: keep as much inventory as you need, no more and no less. Lots of companies though: we can keep even less, it saves money.... no, you have to have as much as you need.
This is just a form of racism.
toyotas USED to be an amazing example. now theyre plastic shit.
Just a quick geek moment. QR stands for "quick response". And it was meant to replace the one dimensional bar code with a two dimensional system. It also worked with Japan's Kanji alphabet.
It's been adopted universally for its data capacity and error correction.
the school days visual novel taught me from a young age to beware of trains
We also have those automated at many metro stations in India. So, a big thanks to the Japanese from India. 🇮🇳❤️🇯🇵
Me losing my mind, thinking all it takes to automate that is a raspberry pie.
*Pi.
You don't eat it! 😂
@@Ron-Ayres my bad 😂
Meanwhile universal studios uses microchips on every paper cup so you can’t refill it 💀💀💀💀💀
Safety doors are basic level standard in South Korea and China. In Japan a lot of stops don't have safety doors, I was surprised they are quite far behind in these safety investments.
I don't know how the technology works, but here in Hong Kong there is a seperate organisation (MTR) that arranges and controls most things for the train system. They have full floor to ceiling doors that automatically open and close, and I never really knew about the concept of not having any type of gate between the tracks and the platform until I visited New York!
Whoever was selling the expensive machines is kicking himself. Imagine, your whole livelihood being replaced by a sticker.
Not really, she's not *exactly* right in how she's saying it. The expensive machine in this case she's talking about is basically train automation. In most of the world, in order to have platform screen doors, the trains need to be automated so they stop consistently in the same place every time and line up with the doors.
The automation is expensive, but it also allows you to run trains closer together and thus move WAY more people per hour. Japan kind of cobbled together a unique solution, but are reaching the point of capacity where they *have* to automate the trains in order to continue to scale the system.
So like, it was a really clever solution but will likely be replaced now that Japan has started to test train automation as of like 2 years ago.
It's less of a Single machine and actually a very complicated system of Signaling and interlocking devices called ATC (Automatic Train Control) which essentially means that Train being run Automatically, it's a technology that is sometimes installed on its own, for Example the PATCO speedline in Philadelphia was the first to use it, with BART, WMATA and the Vancouver Skytrain all being Early Adopters
Idk why countries dont do like qatar, here in metro stations they are fully closed like not halfway like in the video, no FULLY closed like a normal big wall with doors and it opens somehow, i think when the train makes a special noise the doors opens.
You can search them up to understand
This will probably work only in Japan where the people will not scratch the QR code off the glass😅
solution: cameras and have them scan a personal id code to even get inside, then fine them the total cost of running the entire subwaysystem for 24 hours, give them 48 hours to pay off the fine in ite entierity or face jailtime equal to 1 year for every 1000 dollars not paid.
@@theldraspneumonoultramicro405 You dont have to get in the train to spray over or scratch off the QR code.
The sprayer sneak into the depot were the trains are parked to vandalize them, not in the trainstation.
ねー、これは節約に大成功した良い例だよね
In Singapore, all stations have safety doors.
I think the expensive machine is the safety door, no? I mean there are tons of ways to make sure that the doors are aligned like infrared, lasers, sensors etc. and I doubt that their cost hardly matters compared to installing a bunch of mechanical doors at a station
No actually their original plan was to install a system/machine on each train car that can be synced with these doors at the station, which would've cost at least $15,000 PER TRAIN. So the guy who came up with this idea of using QR code is said to have saved 10 million USD.
His name is Seiji Okamoto.
this is interesting. in my city (st. petersburg, russia) closed type stations have been in use since the 60s. it's a station where the tunnel is walled off and the station has its own set of doors which have to sync up with the trains. what they used was just a simple small lamp on the side of the train, which lights up when the train is not in motion and activates a light indicator on the inside of the station wall. simple and effective, no modern technology needed. but yeah, installing lamps onto every train would be more costly than just slapping on a sticker, i guess
@tpjmjmtwdamx2 that just sounds like a scam. Any engineer will tell you you don't need am adjustment that extensive.
Easiest way I can think off is a simple distance detecor that look for something closer than the wall and further away than the train doors.
Use 2 or 3 as a safety measure
Maybe they meant the system, which allows train to stop at the spot where train doors will be alligned to the gates? But the video truly lacks some further explanation
Honestly such a cool thing to find out. Thanks for sharing this~! ❤
So... theoretically... you could.. idk.. use a printer. And do something you're not supposed to.
Theoretically yes, but one train has multiple sets of those QR codes, so one guy can't just make that door malfunction.
@@NorthWoodPen4and track circuits exist
Good improvement. Personally, every time I get on the Vancouver Skytrain, I'm flabbergasted that there are doors on the train and not on the platform. Imagine a high rise building with doors on the elevator car but no doors on each floor. That's basically how our trains are set up. It's madness.
“Accidentally falling into the train tracks…”🤥🤥🤥
"Japan has a lot of accidents relating to people falling into the train tracks regardless of if it's intentionally or not ...". Accidents do happen, especially during rushing hours when multiple people are pushing against one another.
In France, in some cities, the subway works the same way, with doors that prevent you from getting to the tracks and it's been there since the 80s.
I thought the only metro with psd in France was line 14 on the ratp. Which other ones have them?
In Toulouse you don't have access to the tracks in the subway. The doors go to the ceiling and it seemed to have been there for a while...
I don’t get how money is saved with that system.
Maybe whatever centralised automatic door safety system linked to detecting the train arriving has some expensive physical component or licensing and maintenance fee, and just sticking QR codes on doors for cameras is a much cheaper implementation.
@AVeryNormalGuy what you say comes out in this video. I dont know what that guy doesn't get
The issue was that many stations, even the same platform of one station, are quite often operated by different operators (through service of regional commuters into and through the Tokyo Metro system, for example). The different operators had different rolling stock with varying door counts, and the expense of building a proprietary system to signal what train was coming and which doors to open was too much to be viable. QR codes made this process wayyyy cheaper by not requiring a proprietary system to be invented. Now cameras can scan as the train comes in and send a signal instructing which doors to open.
@@백인줄어든다 Well @joshuafletcher991 gave a much better explanation. ;)
I spent half a year in Asia before going to Europe. It was so weird being on train platforms that don't have safety doors
So Japan is the reason why I now have to settle for QR menus instead of paper ones?!
how humble of you informing japanese people of their own rules that they were unaware of.
The streets the hotels and the subway are all full of random spaces and unlevel parts. You really gotta be mindful
And demure
Be very careful scanning QR codes in public areas tho, sometimes they're malicious lol
Japan is a rich country, and many Japanese people are very respectful. They always follow the rules. Starting at the age of two, children in school don't focus solely on academics; instead, they are taught to be polite, respect their families, and follow the law. By the time they turn three years old, they already understand the basic rules of life. Wow!
Japan is not rich, they've been economically declining for decades
yep and theyve been utterly compromised since day 1. every single time ive used a QR its been followed up with email spam telling me crap like i have a parcel waiting.
I am from India amd I would like to thank The Japanese for creating this wonderful invention the QR code. Here in India our metro rail system too have a security door attached to lots of metro stations. When a metro rail arrives, it opens automatically. We have lots of financial transaction system called UPI possible because of QR codes.
Fun fact, replacing the expensive machinery with these stickers saved about 97% of the cost compared to doing platform gates traditionally.
"The Japanese" invented QR codes. That's such a funny way to put it.
Is it not normal to say it like that? its quite normal where i'm from to refer to groups like that especially in history class. I rarely hear Europeon people, always "The Europeans" did this and that etc,
Foolish misattribution for the purpose of a faulty generalization, as bad as saying “the Germans” devised the Theory of Relativity
so, basically Computer Vision
Most peaple know that? I think not. Thanks Japan for the QR code
I was wondering why some many stations have recently installed those safety doors. In the past, I never saw them in Japan. I think I first saw them in Singapore.
"Damn, I wanted to throw myself there but there is a 3.5-foot door on my way! Darn you, government! My plans foiled again!"
They're decently tall, enough to reach heart or clavicle height for most people. The added physical effort to climb and the knowledge you'll have to make a bigger commotion can very well serve as deterrents and also give others waiting on the platform more chance to react and pull you back
Those safety doors can also be seen in South Korea, Singapore, and Thailand.
I was just in Osaka for a few days, yet the train line was disrupted because of a suicide.
I hope we implement this system in Vancouver eventually. Quite a few sad stories of people vaulting themselves into the tracks. Not many people die from this due to the breaking system of the train. I still would like more of a barrier to prevent accidents.
In Toulouse, South of France, there's this kind of machinery since the construction of the underground. But it doesn't use any kind of qr code. And it's completely closed so it's impossible to even fall over the barrier
Exactly, the choice of barriere is strange...
I love your videos, it’s very inspiring me❤❤❤
In Japan: TOP 10 REASONS WHY JAPAN IS LIVING IN THE FUTURE
In Singapore: Cool.
Elizabeth line has the safest doors from Paddington and further, the jubilee line also has it.The doors cover the whole platform from top to bottom so it's more safer
They seem a bit short. Sadly, the real problem still needs to be solved.
They've grown a lot compared to the early 20th century.
Agreed
What is the real problem
@@Lure420 actually if they're not talking about height I have no idea what they're talking about
@@TH-lu9duI think they meant the big suicide rate in Japan
In France there are these subway trains that run on their own(driverless) and there's only a sensor based system in which if the train is in the correct position in front => both doors open simultaneously.
In Germany, they created like a tunnel system so that there is no gap between the train and the platform.
Agreed, the narration is indeed brushing that tragic/important/concerning issue aside.
QR codes are the most unsafe/unsecure form of sharing anything.
QR codes can be dangerous to scan in the U.S.
Why?
@ lots of scammers make their own QR codes that will take you to a malicious website and put them over the legit QR codes
you might get sent to Lemon party
@ ?
@@specialk9999 I’m jet lagged. You might get sent to some freaky diddy party type site.
That is honestly a brilliant solution!
If it's intentional then it's not an accident
The wide platform doors with QR codes were made like that because the line that runs through those platforms have trains with different door layouts, which is what the QR code - most railway lines which use platform doors only run types of trains with the same layout of doors (e.g. the Elizabeth Line in London) so don't have this issue
Many stations on legacy infrastructure rail lines also can't have platform doors installed because the platforms are curved, there are some cases where curved platforms have doors (e.g. Tottenham Court Road on the elizabeth line) but the curve has to be very shallow for it to work
just FYI, don’t scan any QR codes with your phone, there is a new scam where you scan it and the scammer gets control of your phone and finances
Sounds fake as fuck. Unless you tell us any reference to a specific case or exploit that we can look up, I don't believe it.
Sounds like something a boomer would tell you because they don't know how tech works
How to know someones a boomer, without them telling you: Comments like this. A QR Code i literally just a 2 dimensional Barcode. So it can store a lot more information than a normal Barcode. Thats it.
Only a problem if the phone asks you to install software and you say yes.
Not possible until you download a software or enter personal info
Meanwhile in NYC subway, they can’t even get their first platform gates installed even over 2 decades
Because every R-type subway car is different in some way, R46’s and R68/A’s are longer than R160’s. R62/A’s have different door placement than the R142/A’s so trying to put gates is really hard and can only be done on the Flushing, Canarsie, And Queens Boulevard lines right now since each line only uses 1 car type.
People just jump, not accidents. Sad society!
this safety doors are available on all train stations in Singapore too!
the ttc in toronto really needs smth like this
no i actually did not know qr codes were made in japan . Learning every day
Those safety gates are really needed here in the US to prevent deranged nuts from pushing people down the tracks. Too many incidents already.
*Shoujo Rei starts playing*
It's interesting how 99% of those are intentionally 🎉🎉🎉
What you failed to mention is that this only exists on the Toei Asakusa Line system (including Keikyu and Keisei) due to numerous train types running through service with each other. Keikyu also has a 2-door train (2100 series) that would run into the subway as well (specifically Sengakuji on regular service) and it does not open the middle door per car that other trains have. The other system also has the QR code for doors is a station on the Odakyu line which is only a prototype
"Man unaliving myself at train station is so hard these days, maybe i should just not unaliving myself"
Yeh even in Central London, they have those same things but bigger and very accurate and smart!
😊this my first time to know that QR code invented by Japanese 😊
I’m Japanese and I knew this. I think this idea is really clever!
Bruh, here in Singapore, I'm not even surprised. These things are literally everywhere in SG since 1987.
Living here for a year, haven’t seen a single station that doesn’t have the gates, so you must be right
That’s so cool.
Thank you. ♡
can you subvert the entire subway system by slapping a new sticker over the old sticker?
Still dont understand how opening or closing door with QR code make those barriers cheaper.
Me neither. It makes no sense at all compared to a single sensor.
However, it is useful if the trains aren't all the same length, which I think is a better explanation.
In the case of this line, because the number of cars and the position of the doors differ depending on each train, it used to be necessary to install a special device on the train to send a special signal to the platform door, but now a camera and QR code can replace this device, eliminating the need for work on the train and making it possible to install platform doors quickly and cheap.
@mdgw7 i know the the chip which sent the signal is very small and cheap. The signal is very simple to transmit information about train information. Those chips are small and are much cheaper than installing many cameras overheads as in the video.
In India people are living on Qr codes used in UPI truly an amazing thing thanks to Japan for this gift 🎉🎉
yeah most ppl around the world dont know the japanese made QR codes
