TfL - Technology and Data

Disciplines: Project Engineering, Project Management, CAD technology management

TfL is at the forefront of using WIFI to leverage passenger movement metrics across it’s network SRC Infrastructure collaborated with TfL Technology and Data to create WIFI link node models for over 250 stations. WIFI utilisation metrics were built to understand and calculate the traffic/number of passengers between WIFI nodes This quantification of peoples’ movements will enable advertisers and TfL to assess more accurately the value of their fixed advertising assets. SRC Infrastructure led the research, development and finalisation of the required mathematical models for locating communications and systems equipment within underground stations in support of WIFI roll out.


Key achievements include:

  • The development of link-node models for circa 250 stations.

  • Defining the entry and exit points, where appropriate and link the nodes between them within the stations.
