All sorted out; some merged with the better features, some removed.

Lets revert the renames and move it to the right tags, I think!

No probs, I can clean these up. A good end user routing engine would be something like Strava's route builder - lets you generate a course with elevation, based on popularity. Others: RideWithGPS, mapmyride, runkeeper, etc, though they dont use open data under the hood.

osm.wiki/Routing covers the developer tools avail - OpenTripPlanner for example is used by Adelaide Metro, OSRM is also mentioned a lot. I think mapbox also provides some good APIs

Thanks, that seems a more appropriate modelling

Hi! I notice you've added a lot of notes for the bikeway; probably something more suited to a bike routing engine - are they in there for a specific purpose?

Strava user report - "Geen doorgaande weg (ook voor fietsers)" for way/6869718 - but I'm not really sure if that means access private or something else. Do you happen to know?

Thanks, I've updated it based on the GPS traces

Strava user error report: "I'm trying to take the Main Road onto 460, but it keeps backtracking and taking an imaginary street through the woods. " with way/136663375 - I think mapbox imagery might be viewable to double check some of these paths

Is this complete? Strava GPS traces suggest it is.
There are also Strava user error reports:
Temos um circuito muito bom neste local e não podemos marcar como rota. Aguardo ajuda.

Hi,
There's strava user error reports like:
"Won't allow route through a paved bike path. Shows as a dashed line path on map but it is an established paved bike path. "

and

"There is a sidewalk here, but no vehicle access. Should be able to route. "

Are the fences (way/166511148 etc) the most accurate way to reflect access?

Hi, I've got an old (2 years ago) report from strava errors: "Although there is currently construction on the longfellow bridge, it is open to bicycle traffic in both directions. I can't get the my route to go over the bridge though."

Do you know if that's the case currently?

Looking at Australia post, there's several offices on Sydney Rd; and the already mapped post office on Grantham Street.

Hi - note/741825 - you added what looks to be a phone number for this restaurant, is that the case?

http://strava.github.io/iD/#background=Bing&id=w405980926&map=17.00/-39.37608/-11.24524 suggests that these roads need to be realigned to GPS traces

Given that imagery which is seemingly more recent doesn't appear to show the buildings... its worth spot checking and removing obviously wrong data probably.

I've picked this up from reviewing GPS errors via improve-osm.org. Feel free to track down the original import changeset and raise it there; or to add user notes.

Strava users report: "Should be able to cross from south to north here" re node/279628742 - but imagery is inconclusive. Do you know if this is a wall for certain, or could it be a tunnel?

way/122500205 looks complete according to bing imagery, is that the case?

These are close, but don't align to strava gps traces (http://strava.github.io/iD/#background=Mapbox&map=16.00/-112.02065/40.56063 vs way/383642261 for example)

There's no imagery for way/435897007 that seems to match up with the road

way/31605383 and similar don't appear to be visible on imagery
