Good to know Senegal is on task! Yes, now I see on the Senegal wiki
page the same issue I am raising. I think I agree with the comment
about using trunk for "maybe only the (roads) with the highest
quality (at least two lanes of good asphalt) and major topological
roles."<br>
<br>
My take is that trunk designation should indeed be limited to paved
roads with at least 2 full size lanes (that means at least 7 meters
wide = two 3.5 meter lanes). 7 meters wide (+ 1.5 meters on each
side, so total of 10 meter wide base) is the new standard now used
Senegal and Mali I think. This is in line with the 3.5-meter wide
European lane standard and the 12-foot wide US lane standard. <br>
<br>
If Senegal is planning some sessions in 2014 that I feel it might be
the best place to make a proposal to further clarify the standards.
I will subscribe to the mailing list to stay in the loop.<br>
<br>
Sincerely,<br>
<br>

I don't have direct experience of these roads, but
from my perspective, sounds like a reasonable and
informed approach. Hopefully people working in the
region will share their ideas on this. I just wanted
to say, that you should also feel free to contact
directly other people who have edited the wiki page
(check the History), and other people who have
edited these roads in OSM. And yes, remember, it's
all a wiki, so even if it's two steps forward, one
step back, collaboratively getting everything into
the commons doesn't require permission.</span></div>

<div>
<div>Hello:</div>
<div>My name is Vincent Dawans and I
am a Senior Technical Advisor at
Virtue Ventures, a technical firm
dedicated to supporting NGOs and
social enterprises in the developing
world.<span> </span>As a technical
advisor, I do a lot of traveling. I
am currently traveling to West
Africa every 3 months or so. I was
last in Mali and got really
impressed with the accuracy of the
openstreetmap layer (I was using the
MapWithMe android app that gets its
data from openstreetmap); certainly
the level of details in Bamako is
quite impressive, enough that I was
able to go on long walks through the
back streets without ever getting
lost.<span> </span>Seeing all that
good work got me interested in
getting involved.</div>
<div>One of the organizations I work
with is a village-banking
organization around Kayes (Western
Mali) and my plan is to give them
gps receivers so they can start
mapping the many villages in which
they work. I got some old $25 gps
receivers online that I will try
using for that purpose... </div>
<div>I also stared updating the map
for Kayes itself (it needs some
attention). <span> </span>However
as I am looking at the "Highway Tag
Africa" standards I am a bit
confused as to the lack of mention
of the "highway=trunk" and
"highway=motorway" tags.</div>
<div>I am going to take West Africa as
an example since this is what I
know. I feel like the main regional
roads should be consistently marked
as "trunk" and not merely "primary".<span>
</span>Right now some sections are
marked trunk, other primary. By
"regional roads" I mean mostly the
roads that are part of the new
Trans-African Highway Network that
is taking shape.<span> </span>The
Trans-African Highway Network
comprises a series of east/west and
north/south roads crossing the
continent. Here is a good overview
of the Trans-African Highway
Network: <a moz-do-not-send="true"
rel="nofollow"
href="http://en.wikipedia.org/wiki/Trans-African_Highway_network"
target="_blank">http://en.wikipedia.org/wiki/Trans-African_Highway_network</a></div>
<div>My personal experience with that
network is the Trans-Sahelian
Highway (Trans-African Highway 5),
more specifically its first section
running from Dakar to Ouagadougou
which I use on a regular basis.<span>
</span><a moz-do-not-send="true"
rel="nofollow"
href="http://en.wikipedia.org/wiki/Dakar-Ndjamena_Highway"
target="_blank">http://en.wikipedia.org/wiki/Dakar-Ndjamena_Highway</a>.<span>
</span>The section running from
Dakar to Ouagadougou actually splits
into 2 branches from Tambacounda,
Senegal to Kita, Mali (one branch is
the original northern road via Kayes
Mali, and the other one is the brand
new southern road via Kenieba and
Kati, Mali.).</div>
<div>I feel that these roads would
benefit from being more consistently<span>
</span>"upgraded" from primary to
trunk because they are not only
important roads for their respective
countries but are in fact becoming
the backbone of the road network in
their respective regions and serve
as the primary roads crisscrossing
the continent. IMHO they fit the
official trunk definition of "The
most important roads in a country's
system that aren't motorways."<br>
</div>
<div>Whatever decision is made, some
clarification is necessary because
right now some sections of that
network are already marked as trunk
on the map, but in a very
inconsistent manner, with some trunk
roads becoming primary mid way
without reflecting actual changes on
the ground. Here is just one example
for illustration purpose: in Senegal
the trunk tag starts in Kaffrine and
ends in Kotiari, then it becomes
trunk once more in Mali between
Segala and Bamako. In reality there
is no reason why the Dakar-Kaffrine
section and Tambacounda-Segala
section should not be marked as
trunk as well -- or all of it marked
as primary; but not a mix of both...</div>
<div>Additionally, the
highway=motorway tag also needs to
be clarified; on the map, motorways
are already found, mostly in
Northern and Southern Africa with
some also starting to show up in
East and West Africa. For instance
right now there is a short motorway
running from Dakar to Rufisque--
it's a real motorway, a restricted
access road build as per
international standards -- a first
in West Africa I think.</div>
<div>Hence I think the "Highway Tag
Africa" guidelines would benefit
from being expanded with trunk roads
and motorway; if nothing to clarify
the current mixed used of motorway,
trunk and primary tags. I would love
to know what the opinion of the
community is on this matter. I am
willing to help draft some changes
to the guidelines if there is some
buy-in for the general idea
presented here.</div>
<div>I am new to this mailing list and
community, so I apologize if this
was discussed earlier or if I am not
fully informed about the issue.
Thank you for reading my long (too
long) email.</div>
<div>Sincerely,</div>
