Abstract [en]

The number of freeway accidents and injuries in South Korea are in the state standstill since late 2000s. For the prevention of freeway accident, it is necessary to identify risk factors. The purpose of this study is to model freeway accidents effectively by identifying factors which affect freeway accident occurrence. Using regression models such as Poisson regression model and negative binomial regression model, this study examines the safety effects of weather conditions, dangerous driving behaviors, and geometric structures on crash occurrence along a freeway section. This study compares models and scenarios to find out which case efficiently models the crash frequencies. It provides overall understanding of effects of the risk factors on freeway accident occurrence.

This study analyzed the relationship between accident frequencies and weather conditions, dangerous driving behaviors, and geometric structures using regression models. Spatial scope of the study is a 57.6km freeway section of Gyeongbu expressway from West Ulsan IC to Yeongcheon IC. This section includes top 4 frequent accident conzones, thus safety improvement program is applicable after thorough analysis on the causes of freeway accidents. Time scope is from 2007 to 2011.
