In order to ensure smooth traffic at night and traffic safety, reflective signs and reflective safety facilities should be set up gradually along the line. Lighting can be provided at busy and important sections of the road, and local lighting can be used at conditional intersections, crosswalks, etc.

 

Road guardrails shall be set at dangerous sections with construction, falling rocks, landslides, etc; Set up tapered traffic signs on the road sections with obstacles; Guide signs shall be set at the place where the direction of a road section changes. The guidance mark points guide the indicative guidance.

 

The purpose of setting up traffic barrier safety facilities is to ensure the safety of driving and pedestrians and give full play to the role of the highway. However, traffic barriers are not omnipotent, and people still need to consciously abide by road safety regulations.
