Highway Guardrail Safety Roller Barrier with Double Roller
Highway Guardrail Safety Roller Barrier With Cheap Price
Application
1. Small radius curve section
Small radius curves may affect the stopping sight distance in the center divider, requiring increased driver attention to reduce reaction time, and small radius curves require higher line of sight guidance to remind drivers to maneuver better. The use of rotating crash barriers on small radius curves and the color of the rotating barrels will have a visual impact on the driver, creating an enhanced line of sight guidance.
2. Tunnel entrance transition
The different widths of roadbed (bridge) and tunnel cross-sections are important reasons for the high number of accidents at tunnel entrances, which require the transition of guardrails to complete the cross-section change. The rolling barrier is used in the tunnel entrance, which can provide a strong enough guidance function to assist the driver to complete the road environment change under the premise of ensuring the collision prevention demand.
3. Interchange exit triangle end
The interchange exit is sensitive to the direction of travel, requiring the driver to choose the correct route based on the judgment of the guiding information, and the poor combination of interchange exit lines will easily cause the driver to hesitate in making decisions before the exit triangle end, which is an unfavorable factor affecting operational safety. Statistics show that interchange exit sections are often accident-prone, so it is advisable to use rotating movable guardrails to strengthen the guidance and protection of the exit area.
4. Night vision blindness and no street light road
At night when the road lighting is not enough and road border accidents occur, the need to play a warning role through the bright color of the guardrail to the driver, and the driving environment changes also need to be timely reminders to the driver, in order to prompt the driver to complete the vehicle control process conversion. Rotating collision guardrail for the night road environment, can guarantee the collision demand premise, provide strong enough to induce function, assist the driver to complete the road environment changes.
