Hi Ticker, OK, thanks, committed with r4482. Seems the gate only exists to keep cattle inside an area? I think in Germany and Austria a cattle grid would be used.

Hi Ticker,
what are your assumptions reg. default access for a barrier=gate?

Hi Gerd
Here is one, [barrier=gate] on [highway=unclassified]

Hi Ticker,
I think the patch looks good, I hoped for some samples where a correctly mapped barrier on a correctly mapped way shows problems with the existing rules ,e.g. "failure to route by car through a gate".

Hi Gerd
I agree that OSM mappers don't always put the correct access rights on barriers, but often they do, and if wrong it can be corrected. I'm not sure what you mean by "hard to say what defaults should be used"?
I consider that this patch corrects flaws as I listed in the interpreta tion of OSM data relating to barriers and handles some more common barrier types.
A couple of the fixes relate to transport modes I don't use (goods/psv) but the error and fix is textually obvious.
Others relate to combinations like [barrier=gate, vehicle=no], because vehicle is not expanded to bicycle, motorcar, etc.
A common problems I had was failure to route by car through a gate.
Another problem is [barrier={"bollard" etc}, access={anything but "no" or "private"], that would fail to impose a restriction on car, or, indeed, any motor_vehicle

Hi Ticker,
it is difficult to find good rules for barriers Many people don't map the access rights and thus it is hard to say what defaults should be used. At least that was the case when I changed the rules in 2013 ;)
In what situations do you see improvements with your patch?
Gerd

Hi Gerd
The only common bit is filling in the mode hierarchy. It could be moved into an include and shared, but it is only 15 lines.

Hi Ticker,
did not check the details yet but the patch seems to duplicate a lot of stuff coded in inc/access. Is that needed?

Hi Gerd and others interested in routing issues
default style "points" has code that, when option --link-pois -to -ways is in effect, sets highway access and speed restrictions that mkgmap then imposes on the highway that the point is on.
These rules had various errors: - didn't expand the access mode hierarchy, see https://wiki.openstreetmap.org/wiki/Key:access - tested the wrong tag for mkgmap:bus and mkgmap:delivery - if the "access" tag was set, apply this to all modes before processing allowances and restrictions imposed by the barrier; but these actions would have no effect because the the specified mode tags are now all set - assumed that a gate stops motor_vehicle access - didn't handle other common forms of gate - allowed bicycle through kissing_gate and stile
This patch fixes these problems and also adds a speed restriction for all barriers.
The general principle is that barrier rules add specific "no" restrictions that the barrier prevents, but must not add "yes". The "access" tag is a default for all modes not implicitly or explicit handled; there could be, say, osm tags [barrier=stile, access=destination] and this should not imply there is unrestricted foot access.
