The analysis of drivers’ hazard detecting ability using Empathizing–Systemizing model

Since there are drivers who repeatedly have accidents, this research postulated that the lack of hazard perception which is a primary cause of accidents might be determined by individual differences in cognitive traits. The Empathizing–Systemizing (E–S) model was used for the cognitive traits, with Empathizing expected to correspond to ability at hazard perception and fewer accidents and/or incidents (near-accidents). On the other hand, Systemizing was not expected to contribute to them. A web questionnaire was conducted to collect data of accidents and incidents experienced during ordinary driving, and this was analyzed. The results showed that drivers with higher Empathy Quotient (EQ) experienced fewer accidents and incidents. The Systemizing Quotient (SQ) had no significant effect on these experiences. However, the experience of incidents by drivers with high Systemizing Quotient increased when their Empathy Quotient was low. Based on these results, it was suggested that drivers who have a stronger Empathizing function may have a stronger ability at hazard perception. On the other hand, the Systemizing function may weaken hazard perception ability when Empathizing is weak, although it does not have an independent effect.
