Predictors of aberrant driving behaviors of Pakistani drivers by using proportional odds (PO) model

The aim of this study is threefold. First, it explains aberrant driving behaviors by Pakistani drivers. Second, it focuses on the predictors of these behaviors. Third, it compares the aberrant driving behaviors of Pakistani drivers with those of Chinese drivers. Three hundred and ninety-six respondents from Pakistan completed the Internet-based questionnaire survey. Principal component analysis with varimax rotation revealed that drivers in Pakistan are prone to three categories of aberrant driving behaviors: self-willed violations/errors, distracted violations, and risky violations/errors. Three proportional odds (PO) models were used to explore the predictors of such behaviors. Results showed that driver training, possession of a driving license, and driving experience are significant predictors of self-willed violations/errors. In contrast, gender, age, and education level are significantly associated with distracted violations. Moreover, drivers on higher incomes commit fewer risky violations/errors. The results also demonstrate that Pakistani drivers are less disciplined than Chinese drivers.
