The engineering process for a traffic light assistant system on a smartphone for use while driving as an In-Vehicle Information System (IVIS) was accompanied by assessment of subjective usability ratings using questionnaires, such as the System Usability Scale (SUS), AttrakDiff2 and NASA-TLX. The results during the development process are presented and discussed. The SUS was an easy to apply and fast instrument for the project. Nevertheless, caution should be taken when a high percentage of users are repeatedly involved in examining the same system, as this will likely increase the SUS score. © 2013 Springer-Verlag.
