Gate-to-platform and interchange walking times

The request was partially successful.

Dear Transport for London,

I would like to request the estimated walking times from entry/exit gates to/from platforms, as well as interchange times for all rail stations which are part of the Oyster card scheme, including Underground, Overground, DLR and National Rail stations where possible.

I assume you have this information readily available, as it must form part of the Journey Planner's travel time estimates.

Also, please can you tell me the adjustments made to estimated walking times when 'slow' and 'fast' walking speeds are specified in the Journey Planner's advanced options.

Thank you in advance.

Yours faithfully,

Chris Smith

Thank you for your email received by Transport for London (TfL) on 15
December 2011 asking for information about gate to platform and
interchange walking times.
 
Your request has been considered in accordance with the requirements of
the Freedom of Information (FOI) Act and TfL’s information access policy. 
 
Unfortunately, from the description provided, we are unable to identify
the information you require.
 
To enable us to assist with your request, please provide a more detailed
description of the information you’re seeking. For example, are you
looking for interchange time to every individual Tube platform for
stations with multiple lines along with interchange times between each of
the platforms, lines and exits, including both directions on each line
together with any other details you think might help us locate the
information you require.
 
At present we are unsure of how big a task it will be to collate the
information and present it to you in a readable format so we need to be
sure of exactly what you are requesting before we can provide an answer.
 
Please note that the 20 working day deadline for responding to your
request will depend on when we receive satisfactory additional information
to help clarify your request.  
 
If we hear nothing further from you by 13 January your response will be
treated as a new request.
 
In the meantime, if you have any queries or would like to discuss your
request, please do not hesitate to contact me.

Dear FOI,

Thank you for your response, I will try to clarify what I am looking for.

I would like to know the estimated time required to change lines as part of a journey on the London rail network. For example, Kilburn to Liverpool Street may require a change at Baker Street from the Jubilee line to the Hammersmith & City line, I would like to know the time added to the total estimated journey time for this interchange.

Ideally I would like, for each station that lies on more than one line, the time between each pair of platforms within the station (i.e. between platforms where a interchange normally occurs, so not platforms on the same line).
e.g.

Platform From, Platform To, Time

Also, for each station, the time from each platform to the ticket barrier, in both directions. Either every possible entry/exit, the closest entry/exit, or an average entry/exit time (excluding, of course, stations with no ticket barriers).
e.g.

Platform, Gate, Time

If available you could also supply different times for slow, average and fast walkers, and for peak and off-peak times of day.

As I said before, I have in mind the travel time estimates provided by the journey planner. These estimates must include some proportion of interchange time, so I assume that this information is available. I am not sure if the journey planner's estimates include gate-to-platform time (perhaps you could clarify this), if so then this information should also be readily available.

If it makes the task easier, you could provide tables which include station and platform codes and such like, along with reference files which match code to station/platform name, rather than collate the information in a single file.

If it is not possible to provide the level of detail described above, then more coarse grained information will suffice, e.g. an average interchange and gate-to-platform time for each station.

Many Thanks.

Yours sincerely,

Chris Smith

Chris - are you planning to develop or improve an iphone app with this data? :-)

Dear Mr Smith

 

TfL Ref:          FOI-1216-1112

 

Thank you for your further e-mail received by Transport for London (TfL)
on 28 December 2011 clarifying your recent Freedom of Information (FOI)
request.

 

Your request has been considered in accordance with the requirements of
the Freedom of Information (FOI) Act and TfL’s information access policy. 

 

Unfortunately we still require some clarification from you in order to
determine whether we are able to provide the information requested.

 

To enable us to assist with your request, if you could please provide
further clarification on the specific table file format required as this
will enable us to determine what work is needed to collate the data or
whether providing a condensed data set of interchange and platform to gate
times, in Excel format, as you have suggested, might be the better option.

 

Please note that the 20 working day deadline for responding to your
request will depend on when we receive satisfactory additional information
to help clarify your request.  

 

As previously advised, if we hear nothing further from you by 13 January
your response will be treated as a new request.

 

In the meantime, if you have any queries or would like to discuss your
request, please feel free to contact me.

 

Yours sincerely

Dear Gemma Jacob,

The file format could be a flat text file, csv or excel, whichever is easiest. As for the table layout, I would suggest something like:

Station, Gate, Platform, Early am, am peak, inter-peak, pm peak, late pm
-------------------------------------------------------------
Vauxhall, gate x, platform 1, 20, 30, 20, 25, 20
Vauxhall, gate x, platform 2, 40, 60, 40, 50, 40
...

and

Station, Platform a, Platform b, early am, am peak, inter-peak, pm peak, late pm
-------------------------------------------------------------------
Baker Street, platform 1, platform 4, ...

In the Station field you could provide either the name or an id with a separate reference file. In the Gate field you could provide the street name (or other name, e.g. north, south, etc.) or an id along with reference file. The Platform fields should contain the platform numbers as they are in the station. The time-of-day periods of course depend on the data you have available; if you have only a single average time this will suffice.

Many thanks and happy new year.

Yours sincerely,

Chris Smith

Dear Chris Smith

 

TfL Ref: FOI-1216-1112

 

Thank you for your email received by Transport for London (TfL) on 15
December 2011 which was clarified on 5 January 2012 asking for information
about interchange and ticket gate to platform times at stations.

 

Your request has been considered in accordance with the requirements of
the Freedom of Information Act and TfL’s information access policy. I can
confirm TfL does hold the information you require. You asked for:

 

The estimated time required to change lines as part of a journey on the
London rail network. For example, Kilburn to Liverpool Street may require
a change at Baker Street from the Jubilee line to the Hammersmith & City
line, I would like to know the time added to the total estimated journey
time for this interchange.

 

Ideally I would like, for each station that lies on more than one line,
the time between each pair of platforms within the station (i.e. between
platforms where a interchange normally occurs, so not platforms on the
same line).

 

Please find attached two documents providing maximum, rather than average,
interchange and access time values on Journey Planner.

 

The first covers: Underground, DLR and Overground

 

The second deals with London area National Rail.

 

Where stations overlap between these two categories they are included in
both.

 

If this is not the information you are looking for, or if you are unable
to access it for some reason, 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

I'm a bit confused by the underground changes sheet... It says it only takes 4 mins to change from central to northern line at Bank which definitely isn't true, takes more like 8-10 mins. Also ticket office to central line at Ealing Broadway says 2 mins when it's more like 30 seconds. Could this time information be reviewed in order for it to be more accurate??

You're probably taking the longer direction rather than the one that's not evidently shown because TFl want to control pedestrian traffic flow. Sometimes quicker and shorter to take one of the other short cuts which might entail going via another platform or line.
