Two studies were completed to determine in which way information could be presented to drivers on how to merge smoothly and safely into motorway traffic. First a selection of matrix sign information carriers, further referred to as signs, were developed. A selection was evaluated by a focus group on content, information density, lay-out, understandability and usefulness. On the basis of these results eight signs were selected for further analyses. These eight signs were presented on a laptop on which a driving simulator ride was played. Participants evaluated the signs on legibility, understandability, and usefulness. Both a group of older people and a younger control group participated. Results of the older group were the main focus of the study.
As criterion for real world implementation suitability, or at least for further evaluation, a new composite measure was developed in which understandability ratings were counted twice as opposed to legibility and usefulness ratings that were counted once. The 85 percentile score was used to ensure that the majority of users actually assessed the signs positively. Out of the eight selected signs one was rated as very good, and one as very bad.
