FOI request detail

Passenger entries and exits of all tube stations in London

Request ID: FOI-2071-1819
Date published: 07 December 2018

You asked

The information available on Statista are heavily aggregated and only provide data on a summary level, which is not suitable for the project I am doing. The open data on TfL website are a good start but I am afraid they are very limited. The files I have attached are from the sample data that I obtained from the Open Data platform. It provides a complete breakdown of count of passenger entries and exits from all tube stations in London every quarter hour on a typical weekday in 2017. For my project, I require data that is in the same format but for a longer period of time, such as 6 months. To clarify, I need count of passenger entries and exits of all tube stations in London every quarter hour for 6 months consecutively.

Thank you for your emails received by us on 2 and 16 November 2018 asking for information about London Underground passenger counts and incident data.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. You asked for the following:

Time Frame: 01/01/2016 to 31/12/2017 (2 years)
Locations: All 268 London Underground Stations.

Passenger Count:
• Passenger count of entry at all stations at 10 minute interval from 00:00 to 23:59.
• Passenger count of exit at all stations at 10 minute interval from 00:00 to 23:59.

Please note that if 2 years’ worth of data proves to be challenging to retrieve/extract, please send data for 1 year only (01/01/2017-31/12/2017).

Disruptions:
• Time of incident
• Type of incident
• Resolution time
• Location of incident (as precise as possible)
• Actions taken to resolve incident

Track related incidents are published in our London Underground almanac via the following link:
https://tfl.gov.uk/corporate/publications-and-reports/underground-services-performance

However to answer your request in full involves a significant amount of data and we have estimated that it would exceed the cost limit to extract the information you have requested. For example, it would also involve going through millions of rows of passenger usage data and writing a new code in order to extract the level of detail covered by your request.

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. If you want to refine your request or make a Freedom of Information Act request in future, please bear in mind that the Freedom of Information Act allows you to request recorded information held by us. You should identify the information that you want as clearly and concisely as you can, specifying the types of document that you are looking for. You might also consider limiting your request to a particular tube station or period of time.

Although your request can take the form of a question, rather than a request for specific documents, we do not have to answer your question if it would require the creation of new information or the provision of a judgement, explanation, advice or opinion that was not already recorded at the time of your request.

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