<p>Hi,</p>
<p><br>
</p>
<p>useful extensions of tagging schemata, like subkeys or a wider
value range, are always useful to describe the world <span
class="tlid-translation translation" lang="en"><span title=""
class="">more accurate. I would say that such extension would
be useful and helpful. If a router/data user is not interested
in this special feature, he can ignore it. Is this kind of
nodule spread outside of London, too?</span></span><span
class="tlid-translation-gender-indicator
translation-gender-indicator"></span><span
class="tlid-trans-verified-button trans-verified-button"
style="" role="button"></span></p>
<p><br>

<p>Regards Sebastian<br>

<div dir="ltr">Unfortunately I don't think that there is any
better tag to describe them. My dissertation was on using OSM
for visually impaired people and I think that was the only tag I
found. I just did a quick search on overpass (<a
href="https://overpass-turbo.eu/s/LVF" moz-do-not-send="true">https://overpass-turbo.eu/s/LVF</a>)
and looked at <a
href="http://www.blind.accessiblemaps.org/index2.html"
moz-do-not-send="true">http://www.blind.accessiblemaps.org/index2.html</a> and
I found that the tag isn't used much at all. Because OSM is
global it might make sense to use that tag because it is the
standard tag but you could also create a new one
maybe traffic_signals:tactile=yes. What do other people think?</div>
