Scan: Why your passengers don't understand your travel information

What is evaluated The system to be scanned can be the current version or a system yet to be implemented. Elements evaluated can be:

To top.
     dynamic indicators, line naming system, maps, pictograms, route strips, schedules, sign posts, ticket vending machines, time table posters and books, time presentation (time now, time to, time of, digital, analogue) you are here (on maps, route strips, stations and in vehicles), websites, and underlying conceptual structures.



What is the touchstone?

The touchstone is cognitive psychology: is the system compatible with psychological activities the passengers perform for their trip.

  • Perception: use of fonts, icons, luminance, colour, blinking, arrangement of information, position of information, crowdedness.

  • Language: terminology used, multilanguage aspects.

  • Memory: short term memory load, stress, novice versus expert users (e.g. tourists versus commuters).

  • Cognition: can the passengers understand complex system elements (rear and front of train, subdivision of platform, direction of a line, the fare system).


  • To top.
          This touchstone allows an objective scan. The summary includes a quantitative profile presenting the compatibility of the system with the way humans perceive, use language, learn and recall, and with the way they solve travel problems.

    What is not evaluated
  • Opinions of passengers. Existing passenger opinions can be discussed in the cognitive psychological evaluation.

  • Technical state of the system (maintenance). How modern technology is used can be a part of the scan.


  • To top.
         
  • Passenger safety matters.

  • Aesthetics of the system (graphical design), as far as it does not interfere with the comprehensibility of the system.
  •     
  • No comparison is made with other systems. Other systems might be mentioned for explanatory purposes.

  • Passenger friendliness of staff.

    Wayfinding


    architecture signposting naming targets

    Architects’s vision is central in
    signposting
    For architects expressions such as exit
    and side are very important e.g. “
    This sign should be mounted in the hall
    at the exit centrum side (Dutch:
    ”Uitgang Centrumzijde”).
    For the user only the objective
    is of importance:
    “Centre”. That is 66% less text.

    architecture signposting naming targets station cologne
    User’s vision central in signposting
    “Centrum” is all users need.
    All users expect that there is a side and
    an exit at the direction indicated.

    naming public transport international trains

    International train name
    The name of the international train
    on this information board is more important
    than the destination of the passenger.
    It has morevisual power:
    - the information is presented at
      the start of the reading route,
    - the text is in large characters,
    - the colour is different: red.
    Source: Netherlands Railways,
    approx. 1995.

    Elements having two functions,
    one function might be missed.

    the direction indicating function
    of the nose might be missed.


    naming restaurant using a clock
    The name of the restaurant is
    “tijd” (Dutch for time).
    The characters “i”
    and “j̶ form the hands
    of a clock. A creative design.
    Users might not notice the clock,
    nor the name of the restaurant.
