Dear
Susan,
Do
speed cameras save lives?
It
was a pleasure talking with you yesterday on the telephone.
I have
previously sent a letter, similar to this one, to Mr Richard Brunstrom
in his capacity as head of the ACPO road safety committee. I have not received
an adequate reply from Mr Brunstrom (click here),
and I hope you will be able to better answer the main question.
There
are speed cameras being rolled out everywhere we look, but I can find no
evidence whatsoever that the speed cameras have saved lives, will save
lives, or even might save lives. In fact I find quite the opposite. Our
fatal accident rate is showing a very worrying trend indeed.
I've
examined TRL report number 323, which has "excessive speed" as a definite
contributory factor as 6.0% of the population of contributory factors.
I've
looked for other sources of accident causation data in the UK and found
the West Midlands Accident Review, which makes “excessive speed” a very
minor factor indeed in accident causation.
Where
speed is a contributory factor it is often combined with another factor
which makes speed enforcement irrelevant, including for example, reckless
driving, unregistered or stolen vehicle, drunk driving, Police driver on
call, and especially inappropriate speed within the speed limit. One wonders
if there are any excess speed accidents left that could be
assigned to normal motorists exceeding a posted speed limit.
I've
examined TRL 421 and TRL 511, which are not worth the paper they are written
on. In fact they are blatant, non-scientific propaganda, and I am extremely
ashamed of the TRL. I have written to them pointing out some of the serious
shortcomings in the reports and their replies so far have been inadequate.
You can view this correspondence at: http://www.safespeed.org.uk/trl.html.
I've
examined the web sites of the safety camera partnerships and I find hopelessly
inadequate statistics, which never allow for the "regression to the mean"
errors or national trends. When these errors are corrected the claimed
"benefits" simply vanish.
I've
spoken to Police accident investigators who tell me that driver errors
other than exceeding the speed limit are responsible for the vast majority
of road accidents.
As
you know, I have written to Professor Heydeckler asking for some clarifications
concerning the report of the two-year pilot. (click
here)
I heard
you on BBC Radio Wales this morning saying: “We only want to save lives.”
So
my question for you is:
What
evidence do you have that these speed cameras (and the policies which support
them) even might save lives? Any real evidence at all would be welcome.
As you
know I maintain the Safe Speed web site, and I intend to publish your reply
there.
I look
forward to hearing from you in due course.
Yours
sincerely
Paul
