Greening the edge of the toll road by planting grass plays an important role in maintaining soil stability and preventing erosion, especially on sloping land. Toll roads, as vital transportation infrastructure, are often built across various types of land contours, including hilly areas and slopes that are prone to landslides. In this condition, land that is not covered by vegetation is at risk of erosion due to heavy rainwater flow.
