This study focused on fixed object crashes、 the accident type that has the highest percentage of fatal accidents、 on national roads in Hokkaido. Fixed objects were installed in accordance with the Road Structure Ordinance and other installation criteria; however、 appropriate measures may further contribute to a reduction of accidents. In this study、 it was examined how to select locations that should be prioritized for countermeasures against fixed object crashes and how to plan the implementation of countermeasures at the selected locations. From the accident analysis、 it was found that characteristics of fixed object crashes likely to result in death were "steep vertical slope、" "small curve radius、" "narrow roadway width、" "high ratio of daily traffic to daytime traffic、" "large traffic volume of large vehicles" and "high average traveling speed." Based on these characteristics、 13-level indicator for selecting locations of fixed object crash countermeasures was created.
