The purpose of this study was to investigate the feasibility and future promise of decision support systems (DSS A driving simulator study compared three DSSs: a dynamic road sign, displays on the side mirrors, and a vibrating seat (haptic).) inside the vehicle relative to a particular, well‐tested dynamic road sign external to the vehicle. Independent variables included display placement and modality (visual vs. haptic). Dependent variables included measurements of safe driving behavior and usability. A follow‐on focus group study was conducted to gain further insights into the results and improvement ideas. The vibrating seat yielded significantly better safety margins than the dynamic road sign. Haptic DSSs inside the vehicle may have more safety benefits than visual DSSs inside or outside the vehicle. Further investigation is needed to determine what properties of the haptic interface – reduced interference with visual driving tasks, message salience, simplicity, or some combination – are responsible for the advantage. © 2012 Wiley Periodicals, Inc.
