| 抄録(英) | In this study, an accident risk evaluation method for curves with a curvature radius of 50 m or more was developed using Digital Road Map, which provide information on the road alignment except for cross-fall of road. The analysis was conducted on national and prefectural roads around Suwa City and Chino City in Nagano Prefecture, and its validity was verified. The results showed that the accident risk index by this accident risk assessment method and the accident rate, which is the number of accidents divided by the number of curves, are positively correlated. This indicates that the accident risk index for curves can evaluate the accident rate for curves with a radius of curvature of 50 m or more. However, for sharp curves with a radius of curvature of less than 50 m, no correlation was observed. There is room for further study for sharp curve, such as consideration of real-vehicle speed. 翻訳 |
