The data of mountain rural roads, including traffic compositions, operational speeds, number of crashes, and road horizontal alignments, were collected and the impact test conditions of safety barriers were determined. The vehicle type which requires special protection and its actual mass status were considered in the selection of the test vehicle type. Using the method of statistical analysis, the operational speed of the corresponding vehicle type was selected as the impact speed. Based on the analysis of crash cases and road horizontal alignment, the impact angle was confirmed. With a comprehensive consideration of China's current economic conditions, the goal of crash prevention, and the system construction of the performance classes, it was determined that the safety barrier's containment energy is 70KJ and the performance class is B on the mountain rural road. The corresponding impact test conditions are 19-seat minibuses weighing 6t with an operational speed of 42km/h and an impact angle of 25 degrees.
