Summary

This doctoral research investigates the relationship between driver behavior, distraction, and traffic accident generation, specifically focusing on the impact of sending WhatsApp messages while driving. Motivated by high rates of traffic fatalities in Colombia, where human error accounts for approximately 89% of accidents, the study aims to quantify how distraction affects concentration and driving performance across different demographic groups. The research seeks to develop a behavioral model that identifies risk factors and errors associated with distracted driving. The methodology employed a controlled experimental design using a driving simulator capable of replicating various urban and rural scenarios. The study population consisted of men and women aged 16 to 90, selected from a universe derived from seven years of fatality data. Participants were subjected to a distraction task involving the sending of WhatsApp messages while driving. To measure cognitive engagement, the researchers utilized a NeuroSky EEG sensor to capture brain waves and determine the degree of concentration in real-time. Data collected included driving errors, concentration levels, and demographic variables such as age, gender, socioeconomic stratum, and education level. The analysis of the experimental data utilized Machine Learning techniques, including logistic regression, decision trees, and artificial neural networks, to construct predictive models of driver behavior. The results indicated that drivers over the age of 50 exhibited more cautious behavior and were less susceptible to the negative effects of distraction compared to younger participants. The neural network models successfully identified the most common driving errors and classified risky behaviors based on the degree of concentration. The study also developed a mathematical model that correlates user concentration levels with specific driving scenarios, demonstrating that concentration significantly influences the likelihood of errors and accidents. The significance of this research lies in its integration of neurophysiological data with machine learning to create a comprehensive model of driver behavior under distraction. By identifying that older drivers maintain higher caution levels despite distractions, the findings provide nuanced insights into demographic vulnerabilities. The proposed mathematical model offers a tool for analyzing how concentration varies by scenario, which can inform the development of safer vehicle interfaces and traffic safety policies. This approach moves beyond traditional accident analysis by linking real-time cognitive states to behavioral outcomes, offering a scientific basis for mitigating human-factor risks in road safety.
