||The bullnose above
has steel I-beams and will not cushion the crash. A crash on
this bullnose could create more than 20 G's of force on the
occupants of a vehicle.
||This is a close up
photo of the bullnose pictured above.
This terminal is an attenuating terminal and is very effective.
There are some different modifications. When hit, this terminal
flattens the W-beam rail and shoots it away from the car and
driver. Kill and incapacitating rate close to 0%. We have heard
of accidents at 75mph and the driver has walked away.
W-Beam guardrail is the most widely accepted, cost-effective
highway safety barrier in the world.
||The melt is a glorified
BCT and has been redesigned and tested several times.
is used extensively to protect the wood posts and blocks in
our highway guardrail systems. Numerous crash tests have shown
the properties of wood to be a safe and excellent support for
the guardrail systems.
Triple corrugated guardrail is used in Bridge protection and
where increased impact strength is required.
||This terminal was turned
down into the ground to prevent spearing but causes many smaller
cars to roll over. Rollovers are the most severe type of roadside
crashes. Although rollovers occur in only 15% of roadside crashes,
they are responsible for more than 25 percent of all roadside
fatalities. Nearly 75% of all rollovers occur on rural two-lane
roads that have limited right-of-way and were designed to meet
older, less demanding standards. Kill and Incapacitating rate
of turndown is 15-20%
