Dear Mr Newman,

Thank you for your further query which was received on 05/07/2018.

The department has now provided the following response:

1) The data are input into the count database. A QA check is then made to ensure the data has been accurately entered into the database against the original paper copy. Once the check is completed the paper copy is destroyed.

2) All values recorded on site are entered into the database.

With regard to your second query received 09/07/2018 - we will provide a response to the second part of your request ('Also ....' and Question 2) as soon as possible. As Question 1 is a request for additional information could I ask that you resubmit this as a new request (as you are making this via Whatdotheyknow and will need to set up a new reference with them).

Further information about your rights to information is available from the Information Commissioner's Office at www.ico.org.uk

Dear Leicestershire County Council,
Thank you again as your latest response here closes the request fully as I have confirmed through its "status".

My intention was to first see what data is available (now complete), then look at the purposes for which it has been used and its statistical validity as separate issues - hence my request dated 9/7/18. I believe therefore it can be treated as a fresh request rather than an add-on to this and that there is no need so separate Q1 & Q2 as I think you are suggesting.

Yours faithfully,

J Newman

Dear Mr Newman,

Thank you for your further query which was received on 09/07/2018.

The department has now provided the following response:

The surveys are undertaken in accordance with DMRB TA 22/81 which sets out how these data are collected.

Further information about your rights to information is available from the Information Commissioner's Office at www.ico.org.uk

Dear Leicestershire County Council,
As I pointed out in my last message, as you have provided the data I requested the request is now closed, so I do not understand what your latest response relates to. My subsequent request dated 9/7/18 is separate and outstanding. If your message above dated 12/07 is intended to address my 09/07 questions it categorically does not and is furthermore untrue. You need to address my second request independently of the first rather than roll them together.

The guidelines you have quoted here may have some relevance to my outstanding Q2 but you also need to address my outstanding Q1 regarding the uses to which the data has been applied.

I just would point out that the guidelines you quote state clearly that samples should be as large as possible (it suggests 200 minimum, you have only 100) and that sampling should reflect differences by time of day and by day of the week, so you haven't complied with either requirement. Also, in accordance with the FoI Act, you need to provide evidence (if there is any) that you have complied with the guidelines - it is not enough to just say you have. Given that your data is demonstrably invalid, any conclusions etc drawn from it are bound to be spurious which is something I am sure you will be keen to correct.

Yours faithfully,

J Newman

Dear Mr Newman,

Thank you for your email. Please accept our apologies for the confusion. To clarify:

Your email of 05/07/2018 with the further queries -

'1) Input accuracy was audited and any errors corrected before the manually recorded sheets were destroyed and
2) No data was omitted.'

Was responded to -

'1) The data are input into the count database. A QA check is then made to ensure the data has been accurately entered into the database against the original paper copy. Once the check is completed the paper copy is destroyed.
2) All values recorded on site are entered into the database.'

Your subsequent email of 09/07/2018 also appeared, in part, to be raising further queries in relation to our published response and so the following parts of this email were treated as such (as is our usual practice) -

'Also,
- most of the data was collected on Wednesdays between 07:00 & 12:00.
- no data was collected on Mondays, Thursdays, Saturdays or Sundays.
- no data was collected after 12:00.
In fact, only 8% of the available one hour time slots in a week were sampled.

Q:2 What information is there that proves that this very small and limited sampling is fully representative of the overall pattern of vehicle speeds in the locations covered.'

These questions were responded to -

'The surveys are undertaken in accordance with DMRB TA 22/81 which sets out how these data are collected.'

We have noted your observations about this response and will pass them to the relevant department.

Unfortunately we did overlook that you had submitted the request via whatdotheyknow, had registered this as a new request and so had a new response reference from that organisation.

The remainder of your request -

'Question 1 -What further information is available regarding the way in which this data has been used, the conclusions that have been drawn from it and to what extent it has been used to inform actions and/or policy. I am looking for reports or any other documents that reference the data directly or indirectly including any releases to the press.'

has been considered as a new request - logged under FOI 10608. This will be responded to in due course via the email address above.

We do hope this provides clarity.

Kind regards,

FOI Team

Dear FOI,
Thanks again - I think I understand what you have done here, but tacking things on to the first request makes measuring response times against 20 days more confusing.

As regards my query about the timings etc of the sampling, I can tell you categorically that the day/times you have used are NOT representative of a 24x7 week. Indeed one week may vary substantially from another due to say whether schools are on holiday of not and I can see no attempt to take into account such highly relevant matters.
The greatest influence on speed is traffic volume - obviously the greater the congestion, the slower it flows. You have no data that reflects this fact, despite the guidelines emphasising the importance of speed measurements reflecting "free flowing" traffic. Clearly if the data is not representative, any decisions you take from it will be wrong - hence my second request.
Yours sincerely,

J Newman
