But it is stated at the beginning of the page, that it is sometimes useful to adapt <b><a href="https://wiki.openstreetmap.org/wiki/Highways" title="Highways">highway</a> tag usage</b>
to the local physical conditions. And this is the case for many countries from the south where road conditions are quite different from what we expect in countries from the north.<br><br>While mapping for Mali, we were confronted with mappers not able to classify properly the roads. Too many were identified as tracks. In fact, we have to think differently from countries of the north. For
example, north of Mali, you have major roads not paved and badly
damaged at the rainy season. They are still major roads and should be
classified this way.<br><br>The <a rel="nofollow" shape="rect" target="_blank" href="https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa">Highway_Tag_Africa</a> page insist on a simple hierarchy to classify the roads. We make a clear distinction between the hierarchy and the condition of the road. Other tags are used to take care of the surface and road conditions. In later discussions on the HOT list, people suggested that this apply to a majority of countries from the south. In fact, we often have roads badly classified. People working for HOT activations agree in general that these rules are adapted to the context of the countries were we work.<br><br><div> </div><div><span style="font-style:italic;color:rgb(0, 0, 191);font-weight:bold;">Pierre <br></span><br></div> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 10pt;"> <div style="font-family: HelveticaNeue, Helvetica

<div style="font-size:10pt;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;">In this particular case, if there was a hierarchy of roads, it would be less a problem if
the rule that I proposed was followed.

Not that I had objections with what I read there, but it is a duplication of what is already set. Why "Africa"? We should have (and do have) a global system to tag and classify roads, bridge=yes and layer=1 are nothing special to Africa, neither is a hierarchical road system. My suggestion is to delete the page or link to the specific pages in to keep the wiki maintainable. Duplicating the same information over and over again has no sense and raises the risk for inconsistencies.<br clear="none">
