<p>Hi everyone,<br>
<br>
After seeing the message on the weekly, I had to chime in.<br>
<br>
We recently did the same exercise for the city of Bruges and we
measured the width of every street in the old city center. The
reason is that the cycle lobbying group wants to change
legislation in the city center to be more bike friendly. Thé
argument for this is that the streets are to narrow for cars and
that the "cyclestreet"-legislation should apply everywhere.<br>
<br>
But politics aside, I helped a lot measuring the street widths! It
resulted in a nice map:
<a class="moz-txt-link-freetext" href="https://pietervdvn.github.io/MapComplete/index.html?layout=width&lat=51.21&lon=3.2229">https://pietervdvn.github.io/MapComplete/index.html?layout=width&lat=51.21&lon=3.2229</a><br>
<br>
But of course, this is the tagging mailing list, so let's discuss
the technicalities.<br>
<br>
First of all, most of the measurements are made with a laser
distance meter. In order to be very objective, we measured from <i>curb
to curb</i>. Curbs don't move, where as parking lanes, lines
indicating parkings, ... can move. (If no curb is present, wall of
the houses was used). As we are mainly interested in the <i>conflict<b>
</b></i>arising, we measured at the narrowest point of the
street (but ignoring obstacles as street furniture). In a few
places, the GRB (belgian topographic map with houses) was used
(which is very accurate too).<br>
<br>
This width was tagged with 'width:carriageway'. <br>
<br>
(Apart from that, we also added parking lane information, which is
used to deduct how much room of the carriageway is used for car
parking, how much for driving, how much for cycling. Based on
that, we can calculate in which streets there is too little
space).</p>
<p>If a consensus is reached that this should be some other tag, I'm
fine with retagging this for Bruges - but not in the coming month;
the interactive map has to be widely published the coming days and
weeks.<br>
