By means of the codes, passengers have easier access to websites with valid timetables for the relevant stop. Instead of entering www.mobi.wroclaw.pl/przystanek_xxxxx.html, where xxxxx is the number of the stop, it is sufficient to use a special application on your mobile phone. In newer phones, this is pre-installed. Owners of slightly older mobiles may download the application from the Internet and install it similarly to ringtones.
You may download a free application called FOTOKODY by sending a text message with the word "fotokody" to the following free-of-charge number: 8085.
What is a 2D code?
The 2D code is a successor to the bar code. With two dimensions, it is possible to store much more information. The special format of the code makes it possible to store regular texts as well as commands for your mobile phone to visit a website, send a text message or enter data into the address book. Obviously, it is the user who makes the final decision for this action to take place. Instead of writing tediously long texts or complex Internet addresses by means of the phone's keypad, the mobile's owner may simply scan the code.
There are several standards for encoding information in the form of pictures in the world. Two of these appear at the stops:
- the QR code - code compatible with most pre-installed applications in mobile phones
- the photocode - code promoted by mobile operators
What 2D photocodes at stops offer
So far, timetables have required Internet users to select
- type of vehicle (tram/bus)
- type of line (regular/peak-hours/express/fast/suburban/substitute/night)
- line number (over 70)
- route (direction)
- type of day (weekday/Saturday/Sunday, etc.)
- current time
and only then could they obtain information on the time of the next departure.
This is very cumbersome.
It is not much easier to read the timetables at the stop, although we do not need to select the vehicle and itinerary. You still need to know what time it is and if it is possible to travel on several lines in the given direction; you need to look up every timetable on its own.
The 2D code takes you to the website with information on subsequent departures from the relevant stop for vehicles of each relevant line. The departures are listed from the earliest (from the moment when the website is displayed) to the last.
The website contains links to full (regular) timetables.
The most important aspect of this timetable is that it is up to date. Every time you visit the website on your computer or mobile phone, you may check how much time you have to reach the stop.
You need to remember, though, that these are scheduled departures. In the future, the website will contain real times based on data sent from municipal-transport vehicles concerning their location and speed.
