The functions of the machine-non-motorized vehicle guardrail primarily encompass separation, obstruction, warning, aesthetics, enhancement of road capacity, and reduction of traffic accident risks. The machine-non-motorized vehicle guardrail serves as a crucial traffic safety facility, and its roles are manifested in the following aspects:

Separation Function: It segregates motorized vehicles, non-motorized vehicles, and pedestrians, dividing the road vertically to ensure separate lanes for each, thereby enhancing road traffic safety and improving traffic order.

Obstruction Function: The traffic guardrail obstructs undesirable traffic behaviors, such as preventing pedestrians, bicycles, or motor vehicles from attempting to cross the road illegally. It requires a certain height, density, and strength to ensure traffic safety.

Warning Function: By installing the guardrail, its concise and clear contours serve as a warning to drivers, reminding them of its presence and to be cautious of pedestrians and non-motorized vehicles, thereby preventing traffic accidents.

Aesthetic Function: The machine-non-motorized vehicle guardrail, through various materials, forms, designs, and colors, harmonizes and coordinates with the road environment, enhancing the aesthetic appeal of the urban landscape.

Enhancement of Road Capacity: Through physical barriers, it prevents traffic congestion and the mixing of motorized and non-motorized vehicles, ensuring smooth traffic flow on the road.

Reduction of Traffic Accident Risks: It forms a solid barrier on both sides of the road, preventing injuries and losses caused by sudden vehicle deviations, safeguarding equipment and personnel, and enhancing production safety.

The design and materials of the machine-non-motorized vehicle guardrail are diverse, including metals, concrete, or plastics, which possess excellent impact resistance and strength. They can effectively absorb and disperse impact forces during vehicle collisions, mitigating damage and injuries caused by accidents. Proper installation and maintenance are crucial to ensuring the effectiveness and sturdiness of the guardrail, preventing issues arising from improper installation or inadequate maintenance.
