FOI request detail

WiFi Tracking Data

Request ID: FOI-1268-1920
Date published: 19 August 2019

You asked

This is a freedom of information request. Please can you provide me with a dataset of aggregated Tube journey data for the first two weeks of operation of the wifi tracking system on the London Underground that was switched on on July 8th. To be clear, I am asking for any aggregated data that has been collected over the first 14 days, not individual data. For example, perhaps the dataset may be as follows: Kings Cross -> Oxford Circus -> Waterloo = 500,000 journeys Kings Cross -> Green Park -> Waterloo = 30,000 journeys Morden -> Bank/Monument -> Bow Road = 35 journeys Please include any documentation needed to interpret the data. For example, if stations are referred to by an ID number, please include a reference list of which ID numbers refer to which stations. I presume there will be a tool that has been created for accessing this data as this is why TfL has created the tracking system.

We answered

Our Ref:         FOI-1268-1920

Thank you for clarifying your request for information about WiFi tracking on the London Underground.
Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy.
We do not hold the information you have requested. We began the process of data collection on 8 July 2019. There is a considerable amount of work required to transform the depersonalised data connections recorded into patterns of journeys. We will be preparing information to share with our customers after our data teams have had a chance to process and transform the raw depersonalised data.

More information on how we will share our results is contained on our website:
Please accept our apologies that we are unable to assist you further on this occasion.

Yours sincerely
