A pre-screening procedure with a number of candidate Human-Machine-Interaction solutions (visual, auditory and haptic) for the concept of Safe Speed and Safe Distance was carried out. Two groups of 30 test persons participated in the two-phase test procedure. Eleven candidate visual displays for speed information ten alternatives for distance warning and twelve auditory warning sounds were screened by a standard procedure. Two alternatives of haptic feed-back via the accelerator pedal were tested in a mock-up driving seat. As a final task, the participants were asked to build their own “warning package” using alternatives of the different warning modes (visual/auditory/haptic). The activity resulted in three “warning packages” consisting of the combination of these various modes.
