Correlation analysis between risky driving behaviors and characteristics of commercial vehicle drivers

Abstract

In order to define the factors of commercial vehicles risky driving behaviors and develop driver assistant system about commercial vehicles, this article began to screen risky driving behaviors and its factors for the questionnaire in terms of actual accident cases. We determine the sample size by statistical methods, and then we carry on the actual investigation. Based on the survey data, from perspectives of frequency and cause of accident probability, we researched the correlation between risky driving behaviors and their factors by ordinal polytomous logistic regression model. Researches show that driver characteristics have a significant impact to the judgment on the frequency and cause of accident probability of risky driving behaviors. This article stated the importance of risky driving behavior research in commercial vehicles operation from the perspective of human biology.
