A 3-D taxonomy has previously been proposed to define different distraction mitigation strategies that focus on enhancing immediate driving performance. These dimensions include the degree of automation of the mitigation strategy, the type of initiation, and the type of task being modulated by the strategy. The degree of automation can range from a simple driver alert signal to complete system control, with the automation levels being initiated either by the driver or the automation and can modulate either the driving task or the in-vehicle task. This chapter describes characteristicsof different feedback types and the benefits they can provide for enhancing performance and modifying driver behavior. The chapter proposes an additional dimension in designing distraction mitigation strategies--the temporal dimension--which considers the immediate effect of the system on driving performance as well as the long-term effect on drivers' willingness to engage in a distracting activity.
