How Risk Perception Affect Driving Behaviors in Disasters

The disaster environment may has impact on driving behavior, but there are few studies focus on it. In this paper, the sudden earthquake disaster is selected as the research background, and a questionnaire survey combined with experimental research method is used to investigate the impact of driver's risk perception on driving behaviour when performing altruistic task in disasters. An empirical analysis shows that, 1) Driver's risk perception is significantly and positively correlated with average acceleration, while driver's risk perception is weakly and negatively correlated with maximum deceleration. 2) Driver's risk perception has a significant impact on average acceleration, while driver's risk perception has a marginally significant on maximum deceleration. The results show that stronger ability of risk perception may lead to increasing safety level of driving behaviour in disasters and may help with driving performance. The results of this paper may provide scientific support to emergency management in disasters.
