As I’m sure everyone is aware, GTFS is the de facto international standard for storing transit network data.
I would like to enquire if there are any plans to release this data within the API or another public location. And if there are not plans, that this should be a very high priority release for improving the ability for people to work with and analyse TfL network data.
It is a relatively simple format to produce, which TfL should already have maintained somewhere, given that Google Maps has TfL data and Google requests transit data in GTF format: https://developers.google.com/transit/gtfs/reference/?hl=en
The vast majority of software and open source libraries that work with transit data are designed around GTFS due to its prevalence, not being able to apply any of this work to TfL data without creating or finding some sort of conversion software is a severe limitation and makes a lot of projects harder than they need to be.
