Strange for a densely populated country like the NL. However this place was open ocean 100 years ago.

[QUOTE=italystf;115214906]Motorways in mountanious areas are safer from this point of view because parallel tunnels and viaducts (of opposite directions) are usually detached each other and it's impossible to run into the opposite carriaggeway.

It's true, but I meant out of tunnels and bridges... It's ok however

Wire rope barriers are the norm in Australia (at least in New South Wales) for new and upgraded roads where there is space (even roads with hugely wide medians get the treatment). Guard rails remain for older roads and roads where space is slightly constrained. Jersey barriers tend to only be used where space is extremely limited, such as the vast underground road network in Sydney.

After watching this video, I'm amazed that the Modified Thrie Beam system isn't a great deal more common than it is.

California tends to use a mix of concrete center barriers, metal beam guardrails and "nothing" on it's freeways. In urban areas, concrete barriers are the most common while metal beam guardrails can be found on some older stretches of freeway or freeways with a rather wide median. In rural areas, the metal beam guardrail is the most common while on freeways with a wide median won't have a barrier at all (which is what I meant by "nothing").

Prior to 1997, a center median barrier was not required if the freeway had a median that was at least 45 feet wide (that's approx 14m for you metric folks) *unless* the road had a history of head-on collisions.

The standard was changed in 1997 when, in a one year period, 6 people were killed on Highway 85. The 6-lane freeway opened in 1994 but no median barrier was installed because it had a 46-50 foot median. The end results was the standard was changed so a median barrier is required on all high-volume roads with medians less than 75 feet.

There's a chance the standard might be changed again after a horrific accident earlier this year when a FedEx semi lost control, went through the center median (I don't think there was a barrier) and crashed head-on into a bus carrying high school seniors from Los Angeles on I-5 north of Sacramento. The fiery crash killed 10 people. Because that stretch of I-5 is in a rural area, the 1997 standards did not apply.

In Mexico, we have several type of barriers, depending on the geography, volume of traffic and rural vs suburban vs urban... Here some examples of mexican highways:

hard barrier in mountains:









soft barrier:




median in rural areas...this one I think is risky:





mixed barriers: soft and hard:




urban freeways:
Mexico city





NATURAL barriers:

"very soft barrier"





tree barrier! I think these are risky for drivers:







I hope this post was interesting for you guys

Why not some forest between the driveways? Like here on E4 south of Gävle, Sweden

Many metal barriers are being replaced on the UK's motorway network with concrete barriers but I cannot understand why it has to take so long to complete certain sections.

On the M1 between Junctions 16 and 18 the road has been down to 3 narrow lanes to do this change since last year and they are still working on it!!!

When that is done, new works will start to convert it into the oxymoron that is a Smart Motorway. It's a posh way of saying widening on the cheap. Essentially it is a scheme to allow hard shoulder running with varaible speed limits. Years ago the proposal was for full blown widening but this was cancelled in favour of Smart Motorways. The probelm is it's not that cheaper and seems to take just as long to complete which is mental!

They started installing the steel cable dividers in the US on most interstates about a decade ago. The concrete wall dividers are usually only seen in urban areas.

typical interstate/freeway in a low density area
