'Black box' cuts police crashes

Police car black boxes will record details of accidents


Data recording machines are being fitted to Northamptonshire police cars to help improve their safety record.

In the past 12 months, 356 police vehicles in the county have been involved in collisions on the county's roads, and 13 officers injured.

The "black boxes", which will record how the vehicle was driven at the time of any incident, are being fitted to 70 marked police vehicles.

Police hope the device will also cut the cost of police vehicle insurance.

A police spokesman said: "We are keen to reduce collisions and associated stress, injuries and costs."

If the one-year pilot scheme is successful, the black boxes will be fitted to the force's 393 marked and unmarked vehicles.


It will be interesting to see the results of this pilot, in particular how officers will feel about investigators being able to apportion blame more accurately. If the police decide they are happy to be monitored so closely then should it bother the rest of us, as I don't suppose it will be long before all new cars will be fitted with these devices? Perhaps this might improve the general standard of driving? Might it also give a truer measure of what causes accidents, and whether they are really caused by excess speed?

This monitoring malarkey is beginning to snowball now that scameras have brought us to the tipping point. An article on a similar theme is here:

http://www1.computing.co.uk/news/1141542

The actually article in the paper elaborates on the Lorry Road User Charge Scheme (LRUC). Basically, trucks will be fitted with trackers to monitor when, where (and how fast) a lorry travels, and charged accordingly.

As I have been predicting, Speed Cameras will soon be obsoleted by much more
effective technology. This doesn’t mean you will be able to break the limit, though - far from it. The new goods will guarantee that speeders can be detected each time they blip over the limit. In this case, policing policy will be scaled according to gravity of the event, because there will be too many otherwise to be politically acceptable. I reckon road charging is the way they will go, with a higher charges for blippers.

So in Northamptonshire 90.5% of their vehicles had an accident last year. Sorry but that is pretty scary. I thought these people had to drive to a higher standard than the rest of us. That makes police accidents worse than even us bikers :D

I think there is a danger of blurring three issues here.

The incident data recorder (IDR) being installed by the police is to aid in accident investigation and moderate driver behaviour i.e. a safety tool.

The system devised to vary road tax by distance travelled is to make 'the polluter pay' i.e. an environmental tax.

The system devised to warn / record motorists speeding is to make the offender pay i.e. a judicial fine.

The IDR has the distinction of being a genuine safety/research tool rather than a revenue stream determined by the political persuasions of the day.

Is that a climbdown or a contradiction?

You fully realise that if every speeding "offence" could be detected the whole nation of drivers would be banned in the first week.

So you now suggest that "policy will be scaled according to gravity". Well, we've already passed the point where policing isn't based on gravity. So, there seems to be something of a dichotomy.

The thing that scares the hell out of me is that you and similar "simple thinking" individuals will decide that "gravity" is equivalent to the numbers of miles per hour over the limit.

When will you realise that things are not so simple? Road accidents are a problem in psychology, not a problem in physics.

I found a story on Northants police driver retraining from yesterday that relates to IDR and maybe will allay some of your concerns Patch?

Police officers are currently sharpening up their driving skills in suitable locations across the county.

All drivers are being sent on refresher courses as Northamptonshire Police in readiness for the formation of the Force’s new incident resolution teams in the autumn.

Sergeant Daemon Johnson, of Northamptonshire Police’s Driver Training Unit, said the roll-out of refresher courses – taking in around 250 qualified officers - would take several months to complete.

But he said it was essential that all police drivers, both at standard and advanced levels, were fully across the safety criteria guidelines set out by the Association of Chief Police Officers (ACPO) earlier this year. These guidelines clearly put safety at the forefront of the mind of every officer.

He said: “The basic driving course is already underway and is demonstrating to officers how best to stop a vehicle safely and how best to protect the scene of an incident or collision.

“These course refreshers will usually be staged in easy-to-access housing estates such as the Hunsburys or Wootton Fields in Northampton.

“Residents in these areas will clearly spot officers out training in high-visibility jackets with cones in the road.

“We would urge members of the public who have any policing concerns to come out and have a chat with us, especially if they have any intelligence or other information which we can follow up.

“Training will also take place in areas which are considered the biggest crime, disorder or anti-social behaviour hotspots in any given area.”

Every police pursuit that now takes place on the county’s roads will have the emphasis on safe resolution, with officers receiving high-quality training to meet the public’s expectations.

Officers are being instructed that they should steer away from high-speed chases that can potentially put their own welfare and those of suspects and other road users at risk.

Instead, officers are being urged to use all tactical options at their disposal to bring a pursuit to an early and safe conclusion.

Sergeant Johnson added: “This new training will be focused towards ensuring that the right people have the right skills and that the right people are in the right place at the right time to focus on the service required of them by the public.

“These newly-skilled officers will then be able to more effectively deal with today’s crime today.”


Interesting choice of training location?

I can already hear the calls for these boxes to be fitted to all cars.

There must be other groups who will help us fight this. Civil liberties groups for example - nobody wants 'big brother' to know where they are at any given time.

I can't see how you work that out - I never break the speed limit, so it would only be (whole nation of drivers )-1! Just joking. The ideas I am putting forth are related to PID principles, where the correction is related to the magnitude of the error. 3 points and 60 quid has always struck me as a bit of a heavy correction kick for 32 mph, and a bit light for 42 in town. A charge per transgression is much more in tune with the real-time nature of traffic monitoring (indexed to taxable earnings to avoid regressive effects if possible!)

That’s where it’s going, my man! Although, to be fair, I accept you have good points. The limit only accounts for increases in risk due to increased speed (which is a contentious issue), and even then risk is assessed only on average, not for specific cases, so it is not a great metric for individual case judgement. I also appreciate your ‘time and circumstances’ arguments, although I’m more of a ‘one size fits all’ guy in my approach.

But the speed limit is (at present) the only metric of individual events that can be measured easily. As far as I can see, you are recommending a return to expensive individual case judgements (via cops), but this is expensive, arbitrary and inconsistent. Even so, they will always have their place in this for sure. It is right that someone should campaign for that.

But we are stuck permanently with monitoring technology now, and it is best to move the debate on to how to harness it to best serve safety. Hardly a climb down! I think proportionality is the way to go, but we can’t be too academic with these functions – after all, we have to hope for the best but expect the worst in drivers.

If road accidents are confined purely to psychology, I would be happy enough to treat them via public service ads, signage, standards education and what have you. Indeed, this has a role to play, and one of my justifications for supporting limits and their enforcement is that they reinforce a common driving culture, where certain standards (not just acceptable speeds) are in-violable.

Unfortunately, accidents due to bad driving also spill out into the physical and affect me, my family, friends and strangers who might have been my friends. Whether or not you are right in your assertions, I would rather that bad drivers (which seem to be increasing in number) be travelling within the limit than over it.

Fair question, although I don't think these IDR boxes will be doing that exactly. Nothing is said about the police vehicles being tracked, just that journeys are recorded. That sounds like the system is recording where the vehicle has been rather than allowing someone else to find out precisely where it is right now.

It's interesting that the Americans have had this stuff in private cars for a while now. I came across this a while ago, dated March 02. http://www.techcentralstation.com/032902A.html
Quote:
"Even paranoids have enemies," pronounced a bumper sticker on the back of a ratty old Ford I spotted several years ago. I suppose my reaction was vaguely sympathetic, considering a mild disposition in that direction, especially when it comes to the meddling of the nanny state in my personal affairs. I was reminded of the nanny's omnipresence when the subject of automotive black boxes was raised in a recent issue of the Wall Street Journal. The piece concentrated on the question of how the data from air-bag "Event Data Recorders" or EDR's, can be stored and employed. Who owns the data? The owner of the vehicle? The government? Trial lawyers? The police?

All current GM and Ford automobiles and trucks contain EDR's that capture a mass of vehicle data five seconds prior to a crash; speed, throttle settings, braking activity, cornering forces, etc. Other manufacturers are sure to follow, especially if government regulations mandate such devices in the name of safety. (And aren't all such regulations promulgated in the broad-brush panacea of "public safety"?)

Not only will your future automobile probably contain an EDR, but under the hood will be a neat little computer called the OBD, or On-Board Diagnostic system. It records engine data, presumably to help technicians perform proper maintenance and make the repairs. But critics claim that OBD's have the potential of poking into the driving habits of the owner to a point of invading privacy, much like their sister EDR's.

("Sir, your OBD and your EDR indicate that you drive at a steady 75 mph, which is illegal, that you fail to change your oil at the correct intervals, that you drive one-handed while using your cell phone and pick your nose at red lights. This voids your warranty.")

Two computer brains -- one under the hood and the other packed in your air bag system -- record your every move behind the wheel; seemingly harmless enough unless you're involved in a crash or a breakdown, when all that data becomes somebody else's -- probably to your detriment.

Moreover, most manufacturers are offering satellite uplink connections to your vehicle. General Motors 'OnStar' system is prototypical and probably the best known. This looks good at first glance; a simple device for service information without penalty. So too for computerized toll payments like New York State's "EZ Pass" system that permits motorists to ease past toll booths while paying later. A neat convenience that helps to ease congestion. But the potential for mischief is great. ("Sir, the computer says you ran between toll stations A and B at 86 mph, which is 21 miles an hour over the legal limit. You are therefore fined $600 and your license is suspended.") New York authorities deny that such expansion of "EZ Pass" is intended, but that capability is within easy reach of the Big Mamma computer controlling the system.

Add photo radar and other highly sophisticated traffic monitoring devices already in use in Canada and Europe and we face the possibility that all vehicular traffic can be monitored at all times. It's a lay-up with modern computer technology to keep track and record the movement of every motor vehicle in the nation. It could be justified on the basis of safety (of course), speed monitoring, emergency scene responses, gridlock avoidance, etc.

Want to know where every suspected drug dealer, Arab flight student, anti-government dissident, child molester, rapist or Mafioso is driving at the moment? Just hit the "enter" key.

We have opened Pandora's box with the computer. How we square it with privacy issues is a dilemma. We are continually shocked to learn how much data is already stored regarding our personal lives, particularly relating to health and financial issues. But one refuge from the probing eye of Big Brother remains the personal motor vehicle. We can still move about with relative freedom, presuming we obey a few simple rules of the road.

But the potential for intrusion by all manner of snoops ranging from police agencies, insurance providers, government safety types, employers, etc. is on the horizon. Presumably legislators of all political persuasions will rally to prevent any such insidious peeking, leaving only we closet paranoids to fret.

But make no mistake, the ability for computers to look over our shoulders ever millisecond that we are behind the wheel is a clear and present danger. One can only hope that concerns for "public safety" will not totally destroy freedom in this rare and cherished sanctuary of personal privacy.


I'm in two minds about black box recorders in cars. The author of the article only considers the negative aspects of EDR/IDR/black box, but one possible benefit that has occurred to me is that the black box could prove a driver's innocence after a collision. Could be useful both for the police and for insurance compaines. The concerns about the civil liberties side certainly need to be addressed, but a black box doesn't go anything like as far as satellite tracking does.

On the subject of satellite based systems, and just to needle basingwerk a little bit, anyone see the story about train doors not opening? Comments, basingwerk? Sure it's a bug that can be ironed out eventually, but you have to wonder why they didn't just give the train driver a pair of buttons marked OPEN DOORS and CLOSE DOORS. :lol:

BW, are you deliberately ignoring the possibility that by slowing down the average/below average drivers to below 'natural' speed for the road conditions you may increase accident rate/average severity. Say, they might become bored with the road and start hollywood-style conversations (facing the passanger)/obsessed with the speedo/ etc. Pedestrians might become complacent and wander into the road more. Could the KSI(of speed) function have a local minimum at some optimal speed?

Is that an admission (finally) from you basingwerk that you realise that automated detection under the guise of improving road safety is really all about taxation?? The more you can afford, the faster you will be permitted to go??

You are confusing the cause with the effect (again!!). The point is to prevent all accidents from happening by any means possible, not accept that they will happen (more frequently if unchecked by other means) and limit their effect.

I am on the verge of giving up reading your diatribes because, while they look impressive, you are just going to great lengths to talk a lot of rubbish.

Really - then your A) never drive B) you are fooling yourself or C) you are deliberatley driving so far below the speed limit and putting so much of your attention away from where it should be focussed that yoi are a dangerous driver pe se. maybe one iof these " never had an accident but seen hundreds round me " types.

You may one day be embarrassed if you ever have a monitoring device fitted

[quote="r11co"]You are confusing the cause with the effect (again!!). The point is to prevent all accidents from happening by any means possible, [quote="r11co"]

and I applaude that! Well, with one hand anyway, because the only way you can prevent all accidents from happening is by total systematisation of the road system. I have no doubt that will happen in the very long term (think 25 years at least), so we are stuck with prevention andmitigation fot the foreseeable future. I am sure you will agree with me that head-on collisions are very painfull, and head-ons at high speed hurt a heck of a lot more than head-ons at low speed. I know this from experience!

Yes, you have caught me out again. I have been ignoring the possibility that by slowing down the average/below average drivers to below 'natural' speed, you may increase accident rate/average severity.

I have done this on the following count. Bringing such parameters into the discussion introduces many new concepts on which I have no data. Things such as "natural speed levels" may or may not exist. There may or may not be a correlation between perceived speed and focus levels. There may or may not be an advantage gained by such a correlation over and above the increases in risk due to impact and reaction limits, but again, I have no data on that, and in any case such data would be highly suspect (to me at least) due to it's abstract and dependant underpinnings, and its potential for political exploitation from both sides.

Like Gatsobait's .sig, keep everything as simple as possible, but not simpler (or something like that). I know your aversion to common sense (no insult intended, I know exactly what you mean), but at one level at least, this has to 'make sense'.

The above strikes me as a rather unscientific approach. Any data, suspect or otherwise, are better than none at all. Data that may ultimately save lives should be sought with vigour, don't you agree? The assumption that certain data are irrelevant because they are not available defies logic. What do you mean by your post, BW? The argument advanced by SS is that the simple accident causation model that does not include driver psychology does not 'make sense', i.e. that this model is 'simpler than is possible' to paraphrase GB's signature. Is your counterargument to this 'we have no data on this so let's carry on with the set of assumptions that do not rely on such data'? Even though there is cause to suspect that this approach is failing?

Incidentally I think that the 'black box' transmitters have the potential to clarify considerably the accident causation picture. Provided these are tested on a sufficiently large and representative sample of the driving population, they could reveal the true relationship between 'bending the speed limit' and insurance risk, and hopefully and more importantly - the KSIs. This will be part of the data that we are missing now, I hope.

To me, psychology is a remarkably inexact science, and opinions on such things as 'natural speeds' are suspect. When I was 17, the natural speed of the local roads was 115 mph, the top speed of my Avenger GT motorcar. When I was 18, the natural speed of the local roads was 90mph, the top speed of my 250cc motorbike. When I was 25, the natural speed of the M56 was 106mph, the top speed of my Ford escort. When I was 26, the natural speed of the German Autobahns was 125 mph, the top speed of my 1000cc BMW. It may have been the death of my parents that made me think, but in any case, shortly afterwards, the 'natural speed' of the roads seemed to be less and less each year, until now I think the speed limits are reasonable or too high in some cases. How can I explain this 'shifting' natural speed? I can't, other than saying that the whole idea is silly and contrived. You could argue that the speed limit is silly and contrived, except that it has the validity of political consensus and the weight of history behind it, so it seems more silly and contrived to scrap it and start over. Better to use it as a starting block and find better methods to fine tune it against the consensus

I'd make an exception for shaky, psychological stuff.

I'm trying to be logical but ideas about hollywood-style conversations and natural speeds just don't cut it with me either! Your search for the global minimum could be valid, but we have no test-tube to fine tune that. That is why I am in favour of using it as a starting block and find better methods to fine tune it. Nothing is cast in stone, but I really don't think that scrapping it would be good, not would ignoring violations (SafeSpeeds preferred approach), which is a Nelsonian version of the same thing. I am in favour of careful fine turning of the status quo, which I think is getting closer to the minimum for the road system, or would be if people drove 'on protocol' so to speak. How can we do systematic fine tuning of the system when everybody is off-protocol anyway, i.e. speeding and other stupid stuff? You know better than anyone that, to calibrate anything, you need a stable system to compare against. Of course, we could discuss the 'warts and all' political meta-system and include all the mess as it functions. A form of structured anarchy! Oh, let's save it for another day.

The argument advanced by SS is that the simple accident causation model that does not include driver psychology does not 'make sense', i.e. that this model is 'simpler than is possible' to paraphrase GB's signature. Is your counterargument to this 'we have no data on this so let's carry on with the set of assumptions that do not rely on such data'?


My argument is that psychological data is more important than the numerical stuff, but it is much less reliable. It cannot be measured directly, and so cannot be used as an inhibitor on a case by case basis. Speed, on the other hand, can be and so we should expect it to be.

Incidentally I think that the 'black box' transmitters have the potential to clarify considerably the accident causation picture. Provided these are tested on a sufficiently large and representative sample of the driving population, they could reveal the true relationship between 'bending the speed limit' and insurance risk, and hopefully and more importantly - the KSIs. This will be part of the data that we are missing now, I hope


I sincerely hope that they do, although I feel that drivers with lower average speeds will come off with lower risks. I know the 'time and circumstances' arguments are persuasive, but, as well as individual cases, the limits are also a political device to reduce average speeds and increase average safety, and that does not come across on this web site. Only time will tell.

...we are stuck with prevention andmitigation fot the foreseeable future. I am sure you will agree with me that head-on collisions are very painfull, and head-ons at high speed hurt a heck of a lot more than head-ons at low speed. I know this from experience!


Yes, so you keep reminding us. My (last) question to you, however, is what do you think caused the head on collision?

Billions of vehicles pass each other at high speed every day without colliding, so high speed cannot be the causation factor.

There comes a point where attempting to mitigate the effect 'just in case' defeats the purpose, or even becomes dangerous. We could blunten all our kitchen knives to mitigate injuries because, as everyone knows, putting your hand in a bowl of soapsuds and grasping a butterknife hurts a lot less than grasping your carving knife, but, as any chef or tradesman will tell you a blunt knife or chisel can on occasions be far more dangerous than a sharp one simply through inefficiency leading to frustration (a point arthurdent makes above about driving at pointlessly slow speeds).
