Traffic Barrier and its uses | Biri Trading UK

Traffic barrier (also called safety barriers or safety barriers in North America, also called safety barriers in the UK. It keeps vehicles on course and prevent them from hitting dangerous obstacles such as rocks, signals, trees, bridges and trusses.

Sometimes called Armco barriers, from walls, large railings or steep (irreparable) ramps and deep-water intrusions. They are also installed inside split highways and stray vehicles. They prevent entry into the other lane and help reduce direct collisions. Some of these barriers designed to be attached from both sides are called intermediate barriers. Road barriers can also be used to protect sensitive areas such as schoolyards, pedestrian areas and fuel tanks from stray vehicles.

Barriers are generally designed to minimize injury to vehicle occupants, but injuries occur in the event of a collision with traffic barriers. They should only be installed if the impact on the barrier is less severe than the hazard behind it. Whenever possible, we recommend removing, relocating or modifying hazards rather than protecting them with barriers.

To ensure they are safe and effective, road barriers undergo full scale mock testing before being approved for public use. Crash tests cannot reproduce all possible crash methods, but test programs are intended to determine the performance limits of road barriers and provide road users with the appropriate level of protection.

General site for the installation of traffic barrier:
*At the end of the bridge
*Close to the steep slopes of the road boundary
*In drains or water courses with sudden or vertical differences in height
*Near large street signs/lamps or other objects along the road that could pose a hazard.

If you need a barrier, calculate it carefully to determine the length you need. The calculation takes into account the speed and amount of traffic using the road. The distance from the edge of the road to the hazard, and the distance or offset from the edge of the road to the barrier.

Need and placement

The hazards along the road must be assessed according to the hazards they pose to the driver while driving, based on size, shape, stiffness and distance from the edge of the road. For example, small traffic signs and some large signs (ground separation poles) can pose a greater threat to public health and well-being than the obstacles the barrier itself is trying to protect. penalty.  To provide adequate road safety, identify hazardous elements such as fixed obstacles and steep slopes outside the clearing area to reduce or eliminate the need for roadside protection.
