<div>I've updated my map of GB cycle lanes (and quiet cycle routes). Rendered using Geofabrik/Osmosis/Maperitive.

<div> </div><div>It looks to me like there's quite a lot of cycle lanes missing. A lot of cycle lane data is available from DfT for review and copying across, but doesn't appear to have made it's way into OSM yet: <a href="http://wiki.openstreetmap.org/wiki/England_Cycling_Data_project" target="_blank">http://wiki.openstreetmap.org/wiki/England_Cycling_Data_project</a> (and yes this is a bit complicated, but it's quite easy once you get going)</div>
<div> </div><div>A major part of the update to the cycle lane map has been identifying urban main roads based on the presence of residential side roads. This was done using a python algorithm in Maperitive. The results look pretty accurate (not many false positives). In good share-alike style, I can do three things with the output:</div>
<div>1) put the output back in the database, by using existing keys (eg maxspeed=30 mph + maxspeed:source=inferred from presence of residential side streets)</div><div>2) put the output back in the database, using new keys (eg maxspeed:inferred=30 mph + maxspeed:inferred:source = presence of residential side streets)</div>
<div>3) publish the algorithm</div><div> </div><div>It doesn't make much difference to me, but clearly people might find the data useful. So I'm open to views/suggestions.</div><span><font color="#888888"><div>
