Travel in London - Report 9 data - request for statistics and Oyster card data

Ms M Jennings made this Freedom of Information request to Transport for London

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was refused by Transport for London.

Dear Transport for London,

Data from Travel in London report 9 requested.

I previously requested N6 data that could not be provided. Please see table 3.1. I am particularly interested in bus travel data, particularly N6, N19 and N7. I am especially interested to know if you have any data from Oyster cards/swipe pay (London wide or otherwise) that indicates whether there have been changes over time in:
a/ The modal average speed of bus journeys per passenger per day (rather than per bus) and inter-quartile range
b/ The modal average length of bus travel per passenger per day and inter-quartile range
c/ The percentage of bus passenger travel days involving a single bus journeys, two, three, four, five, six etc separating Monday to Friday data, Saturday data and Sunday data

As you previously suggested please could you provide some basic summary statistics about trips by residents of N6 or trips starting or finishing in N6, e.g. mode share,
journey purpose etc. You suggested these would be in 3 year rolling averages to boost
the sample size.

Dear Ms Jennings

 

TfL Ref: 1924-1819

 

Thank you for your request received by Transport for London (TfL) on 20
October 2018 asking for data from Travel in London Report 9.

 

Your request has been considered in accordance with the requirements of
the Freedom of Information Act and our information access policy. I can
confirm that we hold some of the information you require. You asked for
some basic summary statistics about trips by residents of N6 or trips
starting or finishing in N6, e.g. mode share, journey purpose over a three
year period.

 

Unfortunately, the data you have requested in the first part of your
request does not exist at a postcode level (trips by residents of N6) nor
do we have any standard reports to help us derive this data you have
requested.

 

However, for the second part of your request we have run some analysis for
trips originating in N6, by mode and by purpose. This is a 3 year average
(2014/15 to 2016/17):

 

Trips originating in N6
2014/15 to 2016/17 average
Usual workplace 9%
Other work related 8%
Education 9%
Shopping and personal business 14%
Leisure 51%
Other 10%
  Trips originating in N6
2014/15 to 2016/17 average
National Rail/Overground 1%
Underground/DLR 10%
Bus/tram 13%
Car driver 22%
Car passenger 11%
Motorcycle 0%
Cycle 1%
Walk 41%

 

 

If this is not the information you are looking for, please do not hesitate
to contact me.

 

Please see the attached information sheet for details of your right to
appeal as well as information on copyright and what to do if you would
like to re-use any of the information we have disclosed.

 

Yours sincerely

Dear Transport for London,

Please pass this on to the person who conducts Freedom of Information reviews.

I am writing to request an internal review of Transport for London's handling of my FOI request 'Travel in London - Report 9 data - request for statistics and Oyster card data'.

I am especially interested to know if you have any data from Oyster cards/swipe pay (London wide or otherwise) that indicates whether there have been changes over time in:
a/ The modal average speed of bus journeys per passenger per day (rather than per bus) and inter-quartile range
b/ The modal average length of bus travel per passenger per day and inter-quartile range
c/ The percentage of bus passenger travel days involving a single bus journeys, two, three, four, five, six etc separating Monday to Friday data, Saturday data and Sunday data

Whilst I could understand that you might have difficulty collating the data, I cannot accept that you do not hold this information. I wonder whether a similar request that I made a year ago has caused confusion. It may be that although you have this database it has never been interrogated by your statisticians. My current request concerns bus journeys. Each Oyster card registers the start of a journey at a particular bus stop and the time and each Oyster card registers the time and start of each onward journey. It should be possible to identify how many BUS journeys starting in N6 are followed by a further bus journey and what bus that might be and which buses were the start of the journey.

Bus drivers have told me that their bus equipment measures the time taken between bus stops, so it should be possible to know how long the 134, 263 and 43 bus takes between Holloway Road or Junction Road and Highgate Station/Wood Lane or Highgate Station/Highgate Wood. I am interested to know the variation in travel time between peak and non peak hours together with the passenger numbers at peak and non peak hours, and whether this has deteriorated over time.

A full history of my FOI request and all correspondence is available on the Internet at this address: https://www.whatdotheyknow.com/request/t...

Yours faithfully,

Ms M Jennings

FOI, Transport for London

Thank you for your request for an internal review which was received on 16 November 2018.

You have stated that you are dissatisfied with the handling of your request for information under the Freedom of Information Act.

The review will be conducted by an internal review panel in accordance with TfL’s Internal Review Procedure, which is available via the following URL:

http://content.tfl.gov.uk/internal-revie...

Every effort will be made to provide you with a response by 15 December 2018. However, if the review will not be completed by this date, we will contact you and notify you of the revised response date as soon as possible.

Yours sincerely

Dear Ms Jennings

 

IRV-079-1819

 

I am contacting you regarding your request for an internal review
concerning the response provided to FOI-1924-1819.

 

I have liaised with our Principal Data Scientist in our Data and Analytics
team for the purposes of this review and I can advise that the original
response provide to FOI-1924-1819 stating that we do not hold the
information you seek was incorrect.  Please accept my sincere apologise
for any inconvenience that this misunderstanding may have caused.

 

However to try and locate, retrieve and extract all the data you requested
in FOI-1924-1819 would exceed the ‘appropriate limit’ of £450 set by the
Freedom of Information (Appropriate Limit and Fees) Regulations 2004. This
is calculated at £25 per hour for every hour spent on the activities
described.

 

Section 12 of FOIA allows a public authority to refuse to deal with a
request where it estimates that it would exceed the appropriate limit to-

 

(a) either comply with the request in its entirety or;

(b) confirm or deny whether the requested information is held.

 

The estimate must be reasonable in the circumstances of the case and where
we claim that section 12 is engaged, we should, where reasonable, provide
advice and assistance to help the requestor to refine the request so that
it can be dealt with under the appropriate limit. The relevant Regulations
which define the appropriate limit for section 12 purposes are The Freedom
of Information and Data Protection (Appropriate Limit and Fees)
Regulation.

 

Regulation 4(3) of the Fees Regulations states that a public authority can
only take into account the costs it reasonably expects to incur in
carrying out the following permitted activities in complying with the
request:

 

• determining whether the information is held;

• locating the information, or a document containing it;

• retrieving the information, or a document containing it; and

• extracting the information from a document containing it.

 

We do not have to make a precise calculation of the costs of complying
with a request; instead only an estimate is required. However, it must be
a reasonable estimate.

 

A realistic estimate is one based on the time it would take to obtain the
requested information from the relevant records or files as they existed
at the time of the request, or up to the date for statutory compliance
with the request. We are not obliged to search for, or compile some of the
requested information before refusing a request that it estimates will
exceed the appropriate limit. Instead, we can rely on having cogent
arguments and/or evidence in support of the reasonableness of its
estimate. However, it is likely that we will sometimes carry out some
initial searches before deciding to claim section 12. This is because it
may only become apparent that section 12 is engaged once some work in
attempting to comply with the request has been undertaken. If we do start
to carry out some searches without an initial estimate, we can stop
searching as soon as we realise that it would exceed the appropriate limit
to fully comply with a request and we are not obliged to search up to the
appropriate limit.

 

To help bring the cost of responding to your request within the £450
limit, you may wish to consider narrowing its scope so that we can more
easily locate, retrieve and extract the information you are seeking.  We
will, of course, be happy to consider a new, more narrowed request if you
chose to submit one.

 

With regards to your statement of “Whilst I could understand that you
might have difficulty collating the data, I cannot accept that you do not
hold this information. I wonder whether a similar request that I made a
year ago has caused confusion. It may be that although you have this
database it has never been interrogated by your statisticians. My current
request concerns bus journeys. Each Oyster card registers the start of a
journey at a particular bus stop and the time and each Oyster card
registers the time and start of each onward journey. It should be possible
to identify how many BUS journeys starting in N6 are followed by a further
bus journey and what bus that might be and which buses were the start of
the journey” .

 

I can advise that we are able to look at information held on passenger
travel times (this will not be bus travel time) for those customers
boarding at stops located in N6 postcode.  However, please bear in mind
that if you do chose to submit a formal request for this information, as
with above, please make it as specific and narrow in scope as possible as
this information is not readily available and could potentially exceed the
appropriate fees limit under section 12 of the Act.

 

I appreciate that the outcome of this review may be a disappointment to
you and again I apologise for the inaccurate response provided on 16
November 2018. If we can assist you with anything further please contact
[1][TfL request email]

 

If you are dissatisfied with the internal review actions to date you can
refer the matter to the independent authority responsible for enforcing
the Freedom of Information Act, at the following address:

 

Information Commissioner’s Office

Wycliffe House

Water Lane

Wilmslow

Cheshire SK9 5AF

 

A complaint form is also available on the ICO’s website

A further request has been made.

The Information Commissioner has also been approached as there was a lack of information given in the refusal as to how to construct a request within the cost limits.
