Drivers are affected by traffic stress events during driving, in order to explore whether driver characteristics affect driver’s stress response. 21 subjects from high driving characteristics group (Group H) and low driving characteristics group (Group L) were selected by the Wiener Traffic Psychometric test system (VTS) to analyze the stress response characteristics of different driving groups through statistical methods, and the set pair analysis model was used to evaluate the stress response of the subjects. The specific performance is as follows: it is feasible to distinguish driver’s stress response ability by detecting driver characteristics. Improving driving characteristics can help drivers enhance their stress ability. The more critical the situation is, the greater the improvement is. In all stress distance experimets, stress response of Group H is better than that of Group L and the reduction of stress distance had a greater impact on Group L than on Group H. The results prove that it is necessary to provide drivers with more than 1s TTC (time to collision) in traffic stress events.
