<div class="moz-cite-prefix">Hi,<br>
<br>
this is possible but kind of tricky with the current import
procedure. You'll have to determine which OSM nodes belond to
which GH node (keep in mind that for certain situations,
especially for car, one OSM node could also be on an GH edge). So
you will need to store a traffic signal counter per edge and put
it e.g. into the flags. Please read also through:

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am a student majored in computer
science from University of Nottingham. There is a group
project for my second year module. We are working on adding
new features to Graphhopper.</div>
<div><br>
</div>
<div>We try to show the number of traffic signals to user
on Graphhopper.</div>
<div><br>
</div>
<div>We get the number of traffic signals by
using node.hasTag(). Then store it in OSMWay.</div>
<div><br>
</div>
<div>We show the number of traffic signals for specific way on
the front-end. (we do it in the same way as showing road
name of specific way)</div>
<div><br>
</div>
<div>The problem is that user may pass through a part of
road(OSMWay), not entire road(OSMWay) and it shows the total
traffic signals on this roads which is useless for user.</div>
<div><br>
</div>
<div>E.g. There are 2 traffic signals on Ilkeston Road, user
will encounter one of them. We do it in the
way mentioned above and it just shows the total traffic
signals instead of the exact number of traffic signals user
may encounter.</div>

<div>May I ask is it possible for us to show exact number of
traffic signals user may encounter. If we could do it, may I
ask for some suggestions about how to implement it?</div>
