Abstract:

In order to in-depth understand driver’s behavior, a quantitative exploration on the subjective risk perception of driver in curve driving condition is conducted in this paper. Firstly, a method to quantify drivers’ subjective risk perception in curve driving is proposed based on 1/CTLC, 1/STLC, and 1/TAD indicators. Then, the subjective evaluation experiments are devised for latent and overt risk perception characteristics respectively, the driver’s risk estimate is obtained by using the magnitude estimation method, and the results are fitted according to Stevens’ power law to construct a driver’s subjective risk perception model in curve driving. Finally, the driver’s natural driving data are analyzed based on the model. The results show that the risk perception model constructed can reflect the risk perception characteristics of drivers in curve driving condition.
