Crash Barriers also widely known as Armco barriers or traffic barriers are designed to safeguard the vehicles from colliding with hazardous barriers like buildings, boulders, large storm drains or walls. Additionally, these crash barriers can even be placed at the road side in order to avoid errant vehicles from entering deep waters or going through steep slopes. The reason behind the existence of these barriers is basically to reduce the collisions. Hence, they are installed within medians of divided highways so that they are able to prevent such unorganized and wayward vehicles from entering the opposing carriageway of traffic. It is always advisable to use these crash barriers to shield vulnerable areas like pedestrian zones, school yards or fuel tanks.

Roadside accidents that are met due to ignorance or casual approach towards driving can lead to many life threatening events. Similarly, one should even be careful about the factors that can pose a danger to traveling motorists and should come out with preventive measures like small roadside signs. With a crash barrier need, another need that comes along is proper calculations determining length of the need, speed and traffic volume. Crash barriers can be placed at bridge ends, drainage crossings, near steep slopes, near large signs or illumination poles that may pose danger.

• Roadside barriers
• Median barriers
• Bridge barriers
• Work zone barriers

These barriers can either be flexible, semi-rigid or rigid. Hence, depending on the requirement and where it needs to be installed, one should decide the type of crash barrier to be used so that it works as the best safeguarding factor for the travelling motorists.
