Abstract

Road traffic incidents are the 8th leading cause of mortality globally, with 90% of fatalities occurring in low- and middle-income countries. Moreover, these severe accidents are often attributed to the negligence or behavior of vulnerable road users. In Thailand, the mortality rate from road traffic accidents stand at 25 per 100,000 individuals, the highest among ASEAN nations. This study aims to investigate the various risk factors contributing to mortality from road traffic accidents, which have been collected since 2011 through the Highway Accident Information Management System (HAIMS), using statistical methodologies such as Cramer’s V, Information Values (IV), which are employed to identify the most significant causes of mortality. In addition, the mortality had been investigated by deep learning model based on convolution and neural networks algorithms before being explored the significant factors influencing fatality from resulting traffic accidents from deep learning model by numerical techniques for quantifier the likelihood of associated with each significant factor. Three primary factors have been identified by Cramer’s V, Information Value, and numerical analysis: using safety equipment of people, type of road user, and lighting conditions. These findings underscore the importance of targeted interventions, including stricter enforcement of safety equipment use, good road or infrastructure design for preventing accidents with different road users, and improving lighting infrastructure in some sections of a road, which could significantly reduce the road traffic mortality rate. While numerous factors contribute to road traffic fatalities in Thailand, these three factors demonstrate the strongest association with fatal outcomes.
