I'm amused my exaggerated remark should be taken literally because it's actually the very opposite of the proactive response I call for.Graham wrote: ↑Sat Nov 03, 2018 18:19 The point is that there are many possible ways of improving this junction. With the greatest respect, your assumption that I had to be thinking of additional no-entry signs is an example of the blinkered thinking that is, sadly, all too prevalent in road safety circles these days.
There are two very different issues which should not be confused:
A. Failing to stop when met with hundreds of oncoming vehicles is a serious error of judgement. Whatever the excuse, if you are capable of reading a situation that badly then you must not be allowed to drive.
B. Our roads should be designed in such a way that it's impossible to accidentally get yourself into that situation anyway.
The second point is a pipe dream because human beings will always be capable of making a mistake you hadn't anticipated, but it shouldn't stop us from striving to make our roads as safe as possible, especially when the stakes are so high.
To turn to your remark about SABRE, I look at the active threads and I see:
M32 bus gate is being ignored; people suggest the signage be changed
Anecdotes about wrong-way incidents on the M40, A3 and A335; people suggest improvements to all three
New road studs are causing people to miss red lights; people suggest they are changed
Constant complaints about speed limits being ignored; people suggest re-engineering or reviewing the road
Various complaints about signage; people suggest the signage is made clearer
People are proposing changing the entire country's road numbering system because they find having an M1 and an A1(M) confusing!
....so I'm not sure where you get this 'closed minds' idea from, other than a few occasions where the inconvenience caused is so low that the cotton wool approach wouldn't be worth the cost, which is a factor that would have to be considered in the real world. Granted the roads would be a lot safer if every driver who frequently does not pay attention could be incinerated (nb this is not the same as decent drivers who make occasional mistakes), but I'm not sure many highway engineers would consider that anything more than a fantasy.
None of this changes the fact that you won't be able to prevent every mistake possible. You might like to aim for it, you might like to throw millions of resources at it, but it is foolish to think you'll ever achieve it for as long as humans are capable of reading situations wrongly.
