NJ Barrier

Why is Jersey Barrier frequently utilized in place of guardrails in the middle of the road?

The benefit of the RCC New Jersey Barrier is based on the design of its double slope, which helps deflect the car back into the road rather than just crashing into the barrier or crossing over to the oncoming traffic on the opposite side of the road:

Given that it is comprised of reinforced concrete, the RCC NJ barrier is a durable barrier. Additionally, it has good geometric qualities to re-direct traffic onto its lane.

The tire of a car that strikes a barrier at an extreme angle rides up the barrier's bottom slope and is forced back onto the road. When a car approaches a barrier at a sharp angle, the bumper meets the upper slope of the barrier, which lifts the car up until the tire makes contact with the barrier and directs the car back onto the road. As a result, the NJ barrier's two fold slope works effectively for both acute and sharp angles of approach. Even if the NJ barrier does not work as planned, it is strong enough to prevent the car from veering over the road and into oncoming traffic.

Guardrail

If a steel guard rail is there, it will merely serve as a barrier and won't be able to prevent errant cars from returning to the road.

As a result, RCC NJ barriers are typically placed in the middle of the road so that high-speed vehicles that collide with them have a better chance of being diverted back onto the road they were originally traveling on rather than crashing into the guard rail and causing a major accident. Guard rail is available as a barrier on the outer edge of the road where traffic is often slow moving and there is no risk of crossing into oncoming traffic.
