After working hard to get this exclusively in today's Express, Safe Speed issued the following PR at 23:46 yesterday evening:
PR327: BMJ paper reveals that DfT is not fit for purpose
news: for immediate release
In the current issue of the British Medical Journal (BMJ) is an article
comparing Department for Transport (DfT) statistics for serious road injuries
with hospital statistics for serious road injuries. The DfT statistics show a
substantial year on year improvement but the hospital figures show no
improvement whatsoever for a decade.
This means that DfT has a very big problem. After ten years of increasingly
draconian policy the roads have not got safer.
Research from Oxford University, published in the British Medical Journal [1],
has found that Hospital admission statistics for road crash victims have
remained at the same level since 1996. SAFE SPEED PREDICTED THIS FINDING by
analysing road crash statistics and published in early 2004. [2]
In complete contrast, DfT statistics have been claiming a year on year
reduction in Killed and Seriously Injured (KSI) road casualties. KSI is
dominated by the serious injury statistics because the number of serious is
around ten times greater than the numbers killed. DfT policies and DfT targets
are set and measured in KSI, but the new research is very strong evidence that
KSI is not a reliable series.
This means that DfT targets and policies are founded on figures that are wholly
unreliable - and even worse - independent figures show no improvement
whatsoever resulting from DfT policy.
But that's not the end of the story. It still gets worse because we know that
major road safety drivers are continuing to deliver improved safety. These
include:
* Ongoing improvements in vehicle safety, with over 2 million safer vehicles
replacing old ones in the national fleet every year.
* Ongoing improvements in road engineering safety, including new bypasses,
black spot treatments and the transfer of vehicles to safer roads such as
motorways.
* Ongoing improvements in post crash emergency care.
These three drivers alone are sufficiently large and important to result in
reductions in deaths and serious injuries of around 5% per annum even after
taking full account of the growth in traffic.
But now we know that we have seen no reduction in hospital admissions and only
very slight falls in road deaths since 1996. Far from making the roads safer,
DfT policies have misunderstood the nature of road safety and have made the
situation considerably worse.
DfT have used their Killed and Seriously Injured figures for all of the
following:
- To set road safety targets
- To measure achievements against targets
- To evaluate interventions including speed cameras
The new research indicates that THE ENTIRE BASIS for DfT policy and target
evaluation is flawed and meaningless. The DfT's figures are going down, but
they DO NOT represent a genuine improvement in road safety. Instead the changes
in the figures are caused by variations in the degree of underreporting.
The Hospital figures are far more robust with each entry the result of a
medical decision about patient treatment.
Paul Smith, founder of the Safe Speed road safety campaign
(
www.safespeed.org.uk) said: "Department for Transport (DfT) has a dangerously
oversimplified view of road safety. Despite over a decade of ever-increasing
speed controls the roads have not got safer. My extensive research reveals that
DfT policy is making drivers worse. We're spending far too much time
concentrating on the wrong safety factors - and DfT is responsible."
"I've know for three years that the serious injury statistics were behaving
very strangely in relation to other road safety indicators. The only possible
conclusion was that changes in the figures were an artefact of the reporting
process. The new BMJ paper provides very strong additional evidence."
"If road safety had continued to improve at the previous rate (before 'speed
kills' road safety policy, national road deaths would be down to about 2,000
per annum by now. We're 1,200 live a year behind target and I an certain that
bad policy is responsible."
"Department for Transport road safety is not fit for purpose."

DfT are aware that their figures may be 'dodgy' see:

contains (page 3):
"Research conducted in the 1990s has shown that many non-fatal injury accidents
are not reported to the police. In addition some casualties reported to the
police are not recorded and the severity of injury tends to be underestimated.
The combined effect of under-reporting, under-recording and misclassification
suggests that there may be 2.76 times as many seriously injured casualties than
are recorded in the national casualty figures and 1.70 slight casualties,
according to TRL Report 173 Comparison of hospital and police casualty data: a
national study by H F Simpson. The Department is undertaking further research
to investigate whether the level of under-reporting has changed."
