The purpose of this study is to analyze the factors affecting the roundabout accidents near schools. This study gives particular attentions discussing characteristics by pedestrian accident severity using the ordered logit models. In pursuing the above, 63 roundabouts installed before 2014 are surveyed for modeling. the traffic accident data from 2014 to 2016 are collected from TAAS data set of Road Traffic Authority. Such 35variables explaining the accidents as environment, human, geometries, school and roundabout factor are selected from literature reviews. The main results are as follows. First, the ordered logit models (p² of 0.272, _X2 of 24.723) which is statistically significant have been developed. Second, environment factor variable is analyzed to be day or night (X₁), human factor variables are evaluated to be driver gender(X₄), older driver(X_o), pedestrian gender(X₇) and children pedestrian(X₈). Third, geometries factor variable are analyzed to be speed limit sign(X10) and median barrier(X₂₁), school factor variables are evaluated to be hump-type crosswalk(X₂₀), CCTV(X₂₀) and school zone sign(X₂₇), roundabout factor are analyzed to be roundabout sign(X₃₀) and number of circulatory roadway lane(X₃₂). Finally, this study could give some implications to decreasing the accidents severity at roundabout near schools.
