Whether we want it is not really the issue.
I believe the issue is the licensing, and until that is resolved
what we may or may not want is irrelevant.

Hi
Looking at the demo I can't think of a reason why OSM would not want
this data - I believe we do want this data.
Questions I have -
* Are the tags suitable for a global database? Can and should they be
reused elsewhere in UK? or globally? Is there a need for specific
prefixed TfL tags?
* Are there clashes with other cycling data in London? What is a
resolution strategy?
* Will import and integration be performed by automatic processing?
Usual OSM import rules? Clash detection and sanity checking?

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.

Transport for London (TfL) have created a new database of cycling
infrastructure, containing 240,000 assets, covering all of Greater
London.
This groundbreaking database contains every cycle infrastructure
asset within Greater London, including assets on and off-carriageway.
The assets surveyed are: cycle parking; signals; signage; traffic
calming measures; restricted points (e.g. steps); advanced stop
lines; crossings; cycle lanes/tracks; and restricted routes (e.g.
pedestrian only routes).
TfL is keen to make this available to the OpenStreetMap community
under a compatible open license, to ensure maximum use of the CID.
TfL is also potentially willing to consider tool development to help
facilitate sensitive merging in of this data.
There is a new Wiki page, giving full details, at:

Demonstrator map:
-----------------
A demonstrator map, for the purposes only of evaluation by the OSM
community at this stage, has been created by CycleStreets.
This demonstrator map contains only one of the 25 areas that have
been surveyed.
We are specifically seeking comments on data quality and usefulness
of this data from the OSM community. Initial analysis by CycleStreets
is that the data is of excellent quality, and very suitable for
conflation into OSM, to increase both comprehensiveness and metadata
quality.

(Use the controls on the right to change feature type.)
Usage notes: The controls on the right of the map allow the different
feature types to be selected. The OSM layer (available at zoom level
19+) also provides a live feed from the OSM API, to enable quick
comparisons. The two photos of each asset are in the process of being
supplied; those already available and cleared in GDPR terms are
included in the popup.
It is stressed that at this point, no permission is given for re-use
of the data in any way, but TfL strongly intends to make this
available in future. All 25 areas would be covered in the final data
release, not merely the one shown currently in the demonstrator map.
Feedback is very strongly encouraged, as soon as possible. What are
people's thoughts?
