Metal Barriers: Road Safety System
You must have noticed metal barriers running alongside the road along high-speed highways, but do you know why this guardrail system is so important to our modern highways?
What is Road Safety System (RRS)?
Road Safety Systems (RRS) are an indispensable element of modern road infrastructure and are seen as one of the most important life-saving devices.
Road Protection Systems can also provide a protection benefit for road workers where there is frequent maintenance intervention that would require the installation of physical barriers as opposed to temporary working methods.
Road Safety System Requirement
RRSs are costly installations and also need regular maintenance every time a vehicle hits it and is moderately or significantly dislodged. That's why it's so important to understand when you really need a road safety system. For low speed urban streets where vehicle movements are controlled by Traffic Signal Operation, the proximity of important embankments and sensitive pole from roadside etc. RRS is not recommended in most cases, with exceptions such as The requirement for a road safety system comes from a comprehensive RRS assessment process. In simple terms, you must first define the problem. Once you know the problem, assess the risk associated with it. Once you know the risk associated with this issue, find the solution to reduce or eliminate the risk. If the reduction or elimination process proposes to provide an RRS system, you can contact us to design and install the Road Protection System.
How to decide what type of RRS is required?
When the evaluation process recommends providing RRS along the project path, it is time to decide what type of RRS system to deploy. The choice of RRS depends on the following basic parameters:
Enclosure Level – For high speed road with limited working width it is recommended to provide a high containment level. It helps absorb impact with minimal deviation from its original position.
Available Working Width - Working width is the maximum deviation of the RRS from its original position when the vehicle hits the RRS.
Setback Distances – Setback distance is the face distance of the RRS from the side of the main road.
Length of Requirement – When multiple hazards are located along vehicle roads, it is necessary to place a continuous RRS and terminals at both ends. The minimum length of the required RRS is known as the Requirement Length.
Why Do You Need a Terminal at the Start or End Point of a Metal Barrier?
Terminals are provided to absorb the direct impact on the vehicle in the event a vehicle exits without collision with the front face of the barrier. Terminals play a crucial role in adequately ensuring the performance of an RRS system.
Why is Metal Barrier Recommended?
Metal Barriers are provided along the central median and come with a number of advantages and are therefore widely used around the world.
- Almost maintenance free for a long time
- Remains functional even after heavy collisions
- Very high level of limitation
- Requires zero working width
Placing the metal barrier along the median creates a visual barrier on curvatures. In this case, it is recommended to expand from the mid-center. All of the above and many more important analyzes and evaluations are performed before Road Protection Systems are deployed along the carriageway with sufficient retraction distance.
