1.2.1

Personalisation or "advanced" options should be visually part of the journey planner. This means graphical consistency and including them before the "Find Journeys" button so that users will not miss them.

1.2.2

A minimal range of options should be presented. Rather than providing all options that it is possible to provide, only a selection of most effective options should be given.

1.2.3

It must be obvious what the effect of selectiong options will be on the journey search. Any ambiguity in the description of an option will effectively render it unusable.

1.2.4

It should be clear that using advanced options is optional. Although personalisation must be viusually part of the journey planner, it should be obvious that they can be left.
