How accurately do the drivers perceive the hazardous degrees of different mountainous highway traffic risk factors?

The objective of this study was to analyze how accurately do the drivers perceive hazardous degrees of the above four mountainous highway traffic risk factors by making a comparison between subjective risk and objective risk. The results of subjective/perceived risk were based on a self-completion questionnaire survey in a sample of the drivers. 12,866 cases of mountainous highway crashes in Yunnan from 2015 to 2017 were used to establish the “objective/statistical risk” for various risk factors. The results show that as far as differences in hazardous degrees between different mountainous highway traffic risk factors are concerned, the comparisons show high correlations between statistical risk and perceived risk. Both the relative values of statistical risk and perceived risk corresponding to “multi-tunnel sections” are the highest, and the two relative values corresponding to “continuous long downhills” are the lowest. The factors of age, gender, crash experience and the injuries in the crashes of the drivers are pro ved to have effects on the corresponding perceived risk according to the investigation results. The elderly over 65 years old have much less insufficient perception of the mountainous highway traffic risk factors compared with the objective risk they are facing. There are great differences in stati stical and perceived risk between female and male drivers who are between 18 and 24 years old, and the differences in other age groups are not as grea...
