The demonstrator map showing this data from TfL now has an extensive set of
filters for each feature type:
https://tflcid.cyclestreets.net/
E.g. for cycle lane/track, you can now filter for segregated, shared,
prority at sideroads, full/part time, mandatory, stepped track, etc.
These filters match the schema definition at:
https://tflcid.cyclestreets.net/TfL_CID_Schema.pdf
There are also a lot more images loaded now.
My general impression is that the data does seem very accurate. I would
welcome more eyes on this, and thoughts generally on the use of this data
in OSM. Hopefully the filtering will make this easier to find various kinds
of infrastructure.
I am about to circulate a suggested mapping of the TfL data to OSM
equivalents, where equivalent tags exist, for comments.
NB The new filtering controls have a couple of URL persistency bugs - I'll
mop these up shortly. So please be aware of this if sending a link.
