The sharp horizontal curves of the rural roads in mountainous areas has a significant influence on the stability and safety of the vehicle. The simulation method can be used to evaluate the running state of vehicles, and safety improvement measures can be taken accordingly. Based on Trucksim and Carsim, the paper establishes a vehicle dynamics simulation model represented by Jiefang truck and Wuling automobile, and a closed-loop simulation model of the driver with low speed and low traffic volume. A total of 43 simulation experiments are carried out in 4 categories based on different design parameters, and the identification criteria for sharp horizontal curves and continuous sharp horizontal curves of rural roads are determined. Finally, taking the Languan Ancient Path as an example, the treatment methods of sharp horizontal curves are proposed. This paper has practical value for the identification and treatment of sharp horizontal curves on rural roads.
