State of the art

TV screens with further travel information.

On the station there are two types of signs that display time tables and information about delays. The display over the tracks shows a very small amount of information about the next incoming train and a couple of trains after that. To get more detailed information you will have to walk to the bigger TV screens. There are only around three to five of these per station.

According to the article “När kommer bussen? Städje granskar SL:s teknik”, written by Jörgen Städje, (can be found on this link: http://techworld.idg.se/2.2524/1.528860/nar-kommer-bussen--stadje-granskar-sl-s-teknik/sida/2/ledningen-ser-allt) SL has the technology to track busses and trains, and also the ability to predict when a commute vehicle is going to arrive to the station based on reel time data. All the digital signs is connected to SLs main server and has access to real-time timetables and messages about disturbances in the traffic. Every piece of information displayed on the signs on all of SLs stations is collected from this main server.

Who uses the service?

The more detailed TV screens is the first thing travelers lay their eyes on when entering the station because the screens are usually placed at the entrances. So pretty much every one has access to the information as long as they are standing on the station.

Who do they aim to target?

The target user group for the TV screens are travelers standing on the station in front of the screen. The service is very hard geographically bound to the station. You cannot get the information from the web or in an app before you arrive at the station.
