    <p><font face="Verdana">OK, what I found on the Taiwan issue with
        the use of road_name:</font></p>
    <p><font face="Verdana">The key road_name is used on pedestrian
        crossings.  All of them are mapped correctly as nodes being part
        of a highway, however the road_name on the crossing nodes (1997
        in total) is different from the name tag on the highways. So it
        is not clear. No indications if it is an automated import since
        all other keys are very much OK.<br>
        I asked the user to change it.  <br>
      </font></p>
    <p><font face="Verdana">Although they seemed to be related as they
        appeared around the same time and to the same extend as the
        spikes in the road key, they are not related. No road key was
        used in these changesets.<br>
      </font></p>
    <p><font face="Verdana">So still need some research to be done on
        the road key spikes.</font></p>
