Transport for London operator interface

I interviewed several TfL employees as they used an existing UI to find out how it could be improved. Updated designs were created following these interviews and subsequent designs were created as the UI’s technological offerings were developed.

Original interface

(with options for personalisation)

Updated design


The new design had to fit into Costain brand guidelines.


The interface needed to be easy to use for all operators.


The interface needed to organise a lot of information in a restricted space.


Talking to the TfL operators and watching them work was really instructive, it meant I could design a new interface that benefitted the operators’ working practice.
