Analyzing the Impact of Alcohol on Driving Performance and Road Traffic Accidents: Evidence from Simulations and Limited-Time Data from Bangladesh

Abstract This study evaluated the effects of alcohol consumption on driving performance and its contribution to road traffic accidents using simulated experiments and real-world data from 2016 to 2018. The simulated experiments involved 25 drivers, revealing significant impairments in reaction time, vigilance, perception, and control at varying blood alcohol concentration (BAC) levels. Higher BAC levels were associated with increased accident rates, with statistical analysis demonstrating a linear trend between BAC and performance metrics such as average speed (p < 0.05), speed variability (p < 0.01), and lane position deviation (p < 0.01). Real-world data indicated a total of 6,114 accidents in 2016, 5,345 in 2017, and 5,367 in 2018, with a notable decline in serious and fatal accidents by 2018 (fatal accidents decreased from 2,197 in 2016 to 219 in 2018). However, slight accidents rose sharply from 2,662 in 2017 to 4,673 in 2018. Alcohol-related cases peaked at 163 in 2017 before dropping to 125 in 2018. Chi-square analysis found no statistically significant relationship between fatalities and exceeding the legal BAC limit (p = 0.1013 for 2016, p = 0.0981 for 2017, p = 0.1923 for 2018). The study emphasizes the persistent role of alcohol in increasing road safety risks, particularly in accident severity. These findings highlight the importance of stricter enforcement of BAC regulations, public awareness campaigns, and targeted interventions to mitigate high-risk behaviors, such as speeding and poor vehicle control, to enhance road safety outcomes.
