Trends and Determinants of Road Accident Outcomes in Bangladesh: A Statistical Analysis of Deaths, Injuries, and Accidents

Road accidents are a significant public health issue in Bangladesh, leading to substantial fatalities and injuries annually. This study examines trends in road accidents, deaths, and injuries in Bangladesh from 2015 to 2023, identifying key concerns and providing evidence-based recommendations to enhance road safety.To assess the annual trends in road accidents, fatalities, and injuries from 2015 to 2023, identify correlations, and explore underlying causes to inform policymakers on effective interventions.A retrospective analysis of road accident data from 2015 to 2023 was conducted using descriptive and inferential statistical methods. The dataset includes annual records of accidents, deaths, and injuries. Data visualization techniques, such as line graphs were employed to enhance interpretability.The analysis revealed a significant increase in the number of accidents, deaths, and injuries during the period 2015–2021, peaking in 2020–2021, followed by a slight decline in subsequent years. While the number of accidents increased by over 70% from 2015 to 2021, injuries and deaths followed a similar trajectory. The decline observed in 2022–2023 may be attributed to improvements in road safety measures or changes in traffic patterns. The findings highlight the need for stricter traffic regulations, public awareness campaigns, and improved emergency response systems to reduce road accidents and associated casualties. Further research is recommended to explore contributing factors and evaluate policy interventions.Road accidents are a significant public health issue in Bangladesh, leading to substantial fatalities and injuries annually.
