    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

      ​@@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

      @carrela1000 Місяць тому

      ​@@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.

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.

    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

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.

But as for the QR codes on the sides of those pods read at the stations, that is usually completely fine.

      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.

      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.

      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

      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.

    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
