Following a successful pilot programme for the rolling barriers safety system at the underpass from the Subang Airport Road heading into the Federal Highway, the Works Ministry is looking to place more of the rollers on other highways, The Malay Mail reports.
According to its minister, Datuk Seri Fadillah Yusof, no accidents have been reported at the stretch since the first-in-Malaysia guardrail was installed. “The bright yellow colour rollers deter people from speeding and even if there were an accident, the rollers absorb the impact,” he said.
The project was first proposed by the Works Ministry back in October 2016, with the barriers being supplied by South Korean firm ETI. The barriers consists of a steel tube, between which plastic cylinders are fitted. These act as shock absorbers that spin around its axis, reducing the impact of a collision and ensuring the vehicle remains on the road instead of swerving off it.
The underpass was known to have recorded a high number of accidents, and thus, was selected to be a suitable site for the pilot programme. Fadillah has told the Malaysian Highway Authority to discuss with highway operators to identify other suitable locations where the rolling barriers could be installed. “Once a list is prepared, we will start installing the guardrails in stages,” he said.

Look like the rolling barriers will increase the speed of the crashing vehicles compare to normal barriers.
The main purpose of these “Rolling Barriers” is to prevent vehicles who loses control to change its direction according to the road turning instead of banging THROUGH the normal barriers to the opposite side of the road or down the hill to ensure minimum casualties.
Care to explain how rolling barrier increase speed of crashing vehicles?
Something good Gomen has given. What worries me is who will get the contract to install the rolling barriers.
Biasalah, each rolling barrier cost say RM100,000 but crony contract company charge RM1 million.
Just like AES, each camera cost RM1 million wor!
As long as it brings money, so tak kesah
Can it roll?
Your physics fail?
What is the name of the dude ordering these rollers?
Remember Sabah water scandal?
Tons of cash…..we dont want a repeat.
Make sure the people signing the purchase orders r vetted ,have all their bank accounts on surveillance.
Sometimes the rakyat gets syiok at new innovations,but secretly corruption is surfacing unnoticed.Dont be carried away ,yet…all taxpayers.Assuming thousands r to be ordered in future,this a potential goldmine.
As long as it saves lives, so tak kesah
Please install at all major highways for optimal impact. Thank you.
Install at Genting/Cameron next!
should be handy when i lose control of my 4G93T-powered ’96 Proton Wira later….
Good decision to improve road safety. And since Toll Concessionaire makes RM Millions of profit yearly, they should be paying for it without any increase of toll charges. If they put this under capex, may even be tax deductables.
how is this rolling barrier more effective than used tyres in term of impact absorption:?
First of all rolling barriers DIVERT impact more than absorbing impact. To elongate the time of impact to reduce inertia.
Used tyres can’t divert but absorb. One row tyre wouldn’t be as effective. That’s why normally you will see 3-6 rows of tyres at the sharp turning in F1 track. Putting 3-6 rows of tyres on normal roads would require a hefty amount of space.
IN order to make the used tyres ROLL like the rolling barrier you need RIMS (car rims would be to expensive to implement). And if we install car rims to support the tyre, the shock absorbing efficiency would greatly reduced, and it will be heavy. Hence special rims need to be manufactured, strong enough to support a heavy tyre,at the same time it needs light enough to minimise rolling resistance. Which sounds pretty costly to me.
That’s why plastic rolling barriers is the way to go :)
Yeah totally agree that the bright yellow barriers really makes more drivers aware and drive carefully. I always pass by this road. A successful project.
Of course, this got Pros and Cons to implement on road.
For pros, reducing the impact of a collision and ensuring the vehicle remains on the road instead of swerving off it.
How about Cons ?
Will crash to another lane cars & lost control after hit rolling barriers ? more victims in this accident ?
Have to implement more then we will know it is safe or not.
Mr minister, nobody is speeding there because:
1) the road condition is appaling. Potholes right at the corner which can crack your spine, washed away dirt from never ending constructions give motorcyclist free ice skating lesson and poor/absence road line marking which cause those unattentive drivers to stick to their “racing line”.
2) it is bloody congested
I’m not against the rolling barrier implementation. But maybe you need to re-assess the trial programme.
The video showed the rolling barriers was able to absorb & divert the vehicles from direct impact hence causing less harm & injuries to the vehicles & drivers/passengers. Looks like its working. Please go ahead & install on all designated accidents prone roads ASAP. TQVM.
Saw a burnt gen2 just 15m before the rolling barriers about 3 months ago that caused a crawl.
“No accident have been reported”.
Also, 2 lane now become 1.8 lane due to drivers creeping dangerously close to right lane at that stretch. “No accidents” to the barrier but accidents to side mirror?
Also that stupid pothole on the right lane while turning, forcing drivers to creep leftwards, so bloody long also haven’t fix.
Good move govt…safety first
MEX exit to dengkil coming from bukit jalil heading to KLIA. The barrier are wrecked
since already installed a pilot test. why dont tested with real vehicle o hit the barrier for testing? of course use testing car….
As Long as rightly priced cost on our tax money, put it on all the roads pls. Hopefully not hundreds of billions of dollar, a few billions maybe ended up in someone pocket, project stalled, etc
Have they forgot something called ELECTRONIC STABILITY CONTROL (ESC)?
Autonomous braking system must be compulsory in all cars without price increase.
Why waste money on this ? It is the attitude of the monkeys on the road that causes accidents …
