A paper titled “Detection of dangerous driving behaviour with wide-scale data from smart systems and machine learning techniques” authored by Hector Kamvoussioras, Thodoris Garefalakis, Eva Michelaraki, Christos Katrakazas and George Yannis has been published in Advances in Transportation Studies. Specifically, four classification models: Ridge Classifier (RC), Support Vector Machines (SVM), Random Forests (RF), and eXtreme Gradient Boosting (XGBoost) – were developed. These models were utilized to categorize driving behaviour into three defined levels of “Safety Tolerance Zone (STZ)”. The results revealed that the RF and XGBoost models achieved high accuracy, reaching 95% in prediction accuracy. By identifying the factors that influence risky driving behaviour, this framework offers valuable insights for guiding safety interventions , ultimately contributing to enhanced road safety.

This study addresses the complex task of predicting dangerous driving behaviors through a comprehensive analysis of over 356,000 trips, enhancing existing knowledge in the field and promoting sustainability and road safety. Findings indicate that Gradient Boosting and Multilayer Perceptron excel, achieving recall rates of approximately 67% to 68% for both harsh acceleration and braking events. The application of machine learning algorithms, feature selection, and k-means clustering offers a promising approach for improving road safety and reducing socio-economic costs through sustainable practices.
