The art of mapping London’s transport networks – Ian Visits
The “Mapping London” exhibition was put on for TfL staff, to show off the development of mapping London’s various transport networks, and how planning is both driven by mapping, but how maps can change customer behaviour.
For a couple of days, TfL dug deep into its archives and put a large number of maps on display.
