The technical grade of mountainous rural highway is usually low and there are a lot of roadside safety problems such as too many dangerous road sections and lacking of security facilities. So, the safety of roadsides is to be improved urgently. In terms of traffic engineering facilities, this paper put forward an index system for roadside safety assessment. The index system includes road alignment, subgrade and pavement, side slope, roadside danger, state of the slope toe, and road safety facilities. Meanwhile, a safety assessment model was established by applying a weighted analysis. The model can be used to estimate the safety state of roadsides in mountainous rural areas. According to the results of estimation, the rank of roadside safety level was obtained, and this provided the foundation for determining ways to improve the roadside.
