It is well known that a roundabout is an efficient and safe intersection.
However, the safety is generally influenced by the given various conditions.
This study analyzed the effects of the geometric and traffic flow conditions on traffic accident frequency at roundabouts, constructed in Korea since 2010.
Many previous studies have investigated the efficiency and safety effects of roundabout installation.
However, not many studies have analyzed the specific influences of individual geometric elements and traffic flow conditions of roundabouts.
Accordingly, this study analyzed the effects of various influencing variables on traffic accident frequency based on a random parameter count model using traffic accident data in 199 roundabouts.
Using random parameters that can take into account unobserved heterogeneity, this study tried to make up for the weakness of the fixed parameters model, which constrains estimated parameters to be fixed across all observations.
A total of eight variables were determined to be the main influencing factors on traffic accident frequency including the number and width of entry lanes, the presence of pedestrian crossings, the width of the circulatory lanes, the presence of central islands, the radius and number of entry lanes, and traffic volume influence accident frequency.
Based on the study results, safer roundabout design and more efficient roundabout operation are expected.
