The most important change is probably setting appropriate surface
information. I don't know the exact secret sauce magic of
cycle.travel, but surface information is very important for
selecting reasonable routes on a bike - or indeed, any non-foot
method of transportation.
Also, keep in mind, most rural highway=residential from TIGER should
be either highway=unclassified, highway=track, highway=service, or
deleted.
EXCELLENT points, BOTH of these, Paul. Unfortunately, surface tags
are not especially widespread (in the USA, where I am familiar), but
where found, they do make excellent choice points in bicycle routing
logic.
Richard (Fairhurst), if cycle.travel/map's router logic is not paying
attention to surface= tags, perhaps it should, as doing so truly can
improve selected routes. (Not that isn't a fine router already!)
Who knows, it's possible, even likely that OSM gets lots of new
surface tagging if we have a router that pays attention. (Data feeds
usage, usage feeds data, ad infinitum).
