[Objective] To explore whether driving characteristics affect the driver's stress response and behavior in the face of traffic stress events.
[Methods] In this study, the Vienna Test System (VTS) was used to test the participants of the driving simulation experiment. In the experiment, the participants was required to drive at the speed of 60km / h. The distance between the stress source and the tested vehicle corresponded to three kinds of traffic conflict time (TTC): 19.2m (TTC = 1s), 27.5m (TTC = 1.5s) and 35.8m (TTC = 2S). The set pair analysis model was used to evaluate the stress response of subjects. The value range of index evaluation grade was determined by K-means clustering, and the weight of index was determined by entropy weight method.
[Results] The results show that it is effective to judge the driver's stress response ability by driving characteristics, which is manifested in two points: first, under all stress distances, the stress response of participants with high driving characteristics is better than that of subjects with low driving characteristics. Second, when the stress distance is 19.2m (TTC = 1s), the evaluation of participant with high driving characteristics is two levels higher than that of participant with low driving characteristics, but only one level higher under other stress distances. Participants with low driving characteristics are more sensitive to the reduction of stress response distance than those with high driving characteristics.
[Limitations] The sample involved in the experiment is the limitation of lack of various driver’s characteristics
[Conclusions] The results of this study prove the rationality of providing more than 1s traffic conflict time for drivers in traffic stress events, and can provide reference for the design of accident early warning and anti-collision system. At the same time, the mathematical method of grade evaluation proposed in this study is effective. By detecting the driving characteristic ability of drivers, we can distinguish their stress response ability on the road. This study provides a set of feasible rating ideas for the research of road traffic safety.
