Driver Distraction and Stress Detection Systems: A Review

Distracted driving can be defined as driving while being engaged in other activities that can reduce the driver's attention and focus on the road. Distraction has been always a major reason for car accidents. It can be identified by the driver's behaviour and the driving performance. Distraction factors can be classified as intended or unintended diversion of driver's concentration. Stress is a major factor of driving behaviour. It could be the consequence of personal life issues, excess of workload, or road conditions. The identification of distraction factors and stress level remains important and sometimes complicated. This paper presents a review of driver distraction and stress. It also identifies the most used distraction factors, and the latest detection methods and reduction techniques proposed and studied in different studies in the field. Moreover, a discussion about the strong relationship between driver distraction and stress is presented. Finally, a hybrid method is proposed.
