Safe Speed Forums

I have seen (and used) anecdotal reports that approx. 10M 'speeding events' occur every day. Does anybody have a source for this or is it possible to arrive at a crude approximation by reference to published statistics (e.g. total vehicle miles p.a., vehicle/driver population or suchlike)?

It might not be much use to estimate it. That is because a person who is driving at or around the limit will make many transitions as he goes from 29.9 to 30.1 mph etc., whereas a person who is way over the limit on the m-way at 120 mph only makes one transition! So how do you define a 'speeding event'?

In your case I'd assume that it's "anything over 4mph"..

This is actually a much bigger issue than commonly realised, and is another thing that makes prosecuting speeding on a 'per offence' basis pretty much useless and unfair.

I did think this over once and came to the conclusion, pretty much as BW did, that defining a speeding event for counting purposes each day is difficult.
I thought it might be possible if you divided the day up into time segments (say 5 minutes each), estimated the number of people speeding in that that 5 minute segment and extrapolated this for all of the 1560 segments that occur each day. Bear in mind of course the differences in traffic flow and density throughout the day.
By doing this, someone speeding throughout, say, two segments notches up two counts, although someone who bobs around inside the 5 minute segment would be counted only once.

The yardstick needs to be prosecutable speeding offences.

30 miles at 80mph on a motorway = 1 offence
34mph in a 30mph = no offence.

But that still does not give us numbers. I rather think that we have 20 million vehicle movements a day with at least 5 offences on each 'movement' on average. So that's 100 million per day.

Didn't a chief constable come up with a figure a few months back? Can't remember any more sorry.

Cheers

A source for that would be good.

I raised this in another topic:

http://www.safespeed.org.uk/forum/viewt ... highlight=

..but am still none the wiser as to the "legal" definitions of speeding offences with respect to distance / time / whatever.

So Mr. or Mrs. Jo(sephine) Public has no quantifiable idea of exactly how evil they are when thay make a car trip where the speed limit is exceeded.

Yes it would. I agree. I've been racking my brains to try and figure out where I got it from. I think it's in TSGB somewhere, but I haven't found it on a quick search.

Hi All
I drive 250 miles a day, 6 days a week, 8 hours continuously, ( the other 2 hours is actual delivery)
By your by your calculations I break the "Law?" possibly 576 times !! minimium, actually it is probably about half that, as I do drive according to safe driving practice (?) Still this means I lose my licence 24 times a week!!, As I have been on the roads more than 28 years, without accident, only 1 speeding offence ( 3 points and £60 ) about 22 years ago on a moter bike, til last year in july rushing back to let my boss go to his partner as she was dropping child, got another 3 points and £60, ,
this year since starting a new job, I have 2 NIP'S 1 FROM DEVON & 1 FROM DORSET,NIETHER DESERVED, infact I am awaiting NOP to arrive so I can go and fight them on thier own turf,

it is such a pity that so many do not fight their case,as the more who do will clog the courts within 10 weeks , I WILL GO TO COURT EVERY TIME THEY SCAM ME,

Simple maths! scammed * 3 = 180 + insurance penaltys
or scammed * 3 (fight back)£300, if you win, yousave money
if you lose it costs you money

BUT IF ENOUGH FIGHT BACK AND USE DAVID EDGARS DEVICES
HOW LONG WOULD IT BE BEFORE THE COURTS AND CPS AND POLICE DECIDE TO ONLY PROCECUTE REAL CRIMINAL DRIVERS

Have you been over to pepipoo.com? Apparantly Dorset seem to be having problems at the moment with their fixed penalties they have sent out.

I think we should be able to estimate the number of vehicle movements from something in TSGB chapter 1:

Can't say I've found exactly what I was looking for yet.
