Consultancy: public transport information, fast and errorless
| Benefits | Only when shoes have a perfect fit, top performance is possible. Only when the interface fits human movement, perception, language, learning and thinking top performance is possible. For some this is an unusual approach. So are the results. Some examples. |
More complex transport systems can be accepted because passengers understand the system. |

Benefits: train ticket vending machine |
It's called a top performance when almost every Dutchman is able (without help, wizards, soft or living assistants, etc.) within 20 seconds to get a train ticket from a touch screen train ticket vending machine. This includes octogerians and older.
The interface is not based on KISS (Keep It Simple Stupid; one button for 'on' and one button for 'off'). Today the machine sells tickets for adults, children, dogs and bicycles. Of course, there are single, round trip, weekend trip and 'no date' tickets. But there are whole day tickets, tickets for a detour, departure from another station and a trip to several stations as well. Destinations can be: all stations in the Netherlands, some abroad, and even a concert. In one purchase the passenger can obtain several tickets of the same kind or a combination of any kind of tickets. Each day more than 120 000 are sold.
Human Efficiency specified the interface for this vending machine. Now electronic ticketing is elaborated; no vending machines, no ticket windows; enter somewhere in the Netherlands public transport and simply leave it somewhere. No interfaces, some think. Indeed, no interfaces for pressing buttons and inserting cards. Explaining the passenger what the computers watching his trips are thinking is a real challenge for cognitive psychologists.

Benefits: tructuring departures on dynamic displays |
Usually departures are arranged using trips of planes, trains or busses. |
Arrangement using destinations in not common.

A much more marked difference appeared in the selection of suboptimal trains: 3% for the alphabetical but 14% for the chronological indicator. The mean search time for the chronological indicator took 7 seconds and the alphabetical indicator 4 seconds, per train found (Anova f=15.2, p<.001). This is nearly twice as long for the chronological indicator. The mean delay that the passengers would have experienced if they had really taken the train they selected was, when using the chronological trains indicator, four times greater than when using the alphabetical destinations indicator: 3.6 minutes to 0.9 minutes. This shows an even greater difference between the different types of presentation.

'Junction' stations give more problems than do other stations and, with these, the chronological trains indicator performs much more poorly than does the alphabetic alphabetical destinations indicator. The cause of these problems is that the train schedules of junction stations are complicated. These kinds of station can often be reached by both ‘all stations trains' and 'express trains'; they can be reached directly or by a detour; and several trains for this kind of station maybe leaving at almost the same time.
After having searched for five departure times on a chronological trains indicator and five on an alphabetical destinations indicator, the passengers compared indicators (see table VII). These subjective scores were 6.1 for the chronological trains indicator and 8.2 for the alphabetical destinations indicator (score 1 was poorest, score 10 was best). It can be concluded that passengers perform better on all categories measured with an alphabetic list of destinations (an ordinal list) that with a chronological list of trains (random list). |
