Abstract:

This study introduces a method for calculating the height of antiglare panels for concave vertical curves. The concave vertical curve is divided into a straight-slope section, transition section, and middle section. The height of the antiglare panels in the middle section is designed based on the glare distance. The height in the straight-slope section is designed based on the height calculation formula given by the Chinese standard. The height of the antiglare panels in the middle section is greater than that in the straight-slope section. There should be a gradual transition in the height difference of the antiglare panels in the transition section. The height gradient of the antiglare panels in the transition section must be designed to ensure visual continuity and comfort for drivers. In the transition section, the transition design is carried out on the height difference of the antiglare panels using the UC-Win/Road simulation software to determine the acceptable height difference for drivers. When the radius of the concave vertical curve does not exceed 30,000 m, the height of the antiglare panel is required to be designed, and the height difference should not exceed 6 cm.
