According to an article in the local paper, the government is providing funding for a cable barrier to be placed in the median of 99 from 80th St. in Ladner to 24th avenue in S. Surrey.
This was apparently after a bad accident last summer where a driver crossed the median and entered opposing traffic after trying to avoid a ghost driver (a driver who was travelling the wrong way on Hwy. 99). The driver taking the avoiding action ended up in a collision on the other side of the highway which paralyzed him.
The person travelling the wrong way was shortly thereafter involved in a head on collision that killed him/her and injured another driver they hit.
I think the cable barrier would be good to prevent cars or trucks crossing the median and ending up on the opposing side, but I also think the cables would be potential added risks for motorcyclists. A cable could potentially sever limbs or cut a body in half.
I found an interesting sudy of motorcycle accidents done in Germany and Australia. It does mention that these types of barriers tend to snag limbs, thus guiding the body into posts and subjecting it to large decelerative forces.
I have also read reports of riders losing various body parts during impacts with such barriers.
Apparently they have been banned in some countrlies.
Thus what may increase the safety of cars travelling down that highway may adversely affect the safety of riders.
Has anyone had any experiences with these matters?
