Change "highway=*; construction=yes" to "highway=construction; construction=*"

[mkoniecz]

There are two methods for mapping road under construction[1]. One is [highway=construction; construction=*], second is [highway=*; construction=yes].

First method is significantly better as it is easier to process and not processing construction-related values is not resulting in wrong data (fail-safe tagging).

In addition construction=yes is used 3366 times with highway=*, highway=construction is used 79730 times[2].

[highway=construction; construction=*] also has wider support (for examples see JOSM and default map style).

I propose to change in validator [highway=*; construction=yes] to [highway=construction; construction=*].

Below I am attaching validator rule accomplishing this from my custom validator rules. Unfortunately due to #10913 it is impossible to write single rule for this task and it is necessary to have separate for every processed highway value.

Script used to generate this set of rules is attached as comment to validator rule below.

The problem here is that 'construction=yes' and 'construction=minor' are tags used by people to indicate that the road is currently under-construction, but is still open to traffic.

This is quoted directly from the construction page on the wiki:

====
Additionally construction=minor can be used for existing highways which will be modified or repaired without being closed. In this case we don't set highway=construction but leave it at its default value.
====

Maybe suggest to people to convert 'construction=yes' to 'construction=minor' would be better in this case via the validator? Especially if the road is already open to the public, but is being repaired/repaved/rebuild while still being in use.

[mkoniecz]

Using construction=yes as equivalent of construction=minor is not documented on this wikipage. construction=minor tag is described there as a separate tagging scheme ("Additionally construction=minor can be used for").

So using 'construction=yes' to indicate that "the road is currently under-construction, but is still open to traffic" is tagging error given that other meaning is documented (also, in my experience people are using construction=yes to describe construction resulting in lack of access).

Also Humanitarian style is considering "highway=*; construction=yes" and "highway=construction; construction=*" to be equivalent ​https://github.com/hotosm/HDM-CartoCSS/issues/234#issuecomment-57103077 (I am not aware about other data consumers supporting this tag).
