Hello OSRM,<br>
<br>
I do believe there is need for a "drive node" for a multitude of
cases related to OSRM, which I doubt OSM'ers takes into focus.<br>
<br>
Example: Using airports or municipalities as waypoints in a
navigation, shows two problems.<br>
<br>
Problem 1: Airport "nodes" are usually somewhere on the runway. Very
frequently that results in a navigation for an airport service road
opposite the terminal. We have identified the street access nodes
for all airports in Europe and currently add Russia.<br>
Problem 2: On administrative boundaries I was <i>very</i> surprised
to find thousands and thousands in "civilized Europe" without an
"admin center". Or "admin center" being nothing but set as a
"centroid" in the middle of nowhere. Using those for drive time
calculations we had up to 30 minutes differences i.e. in the Alps.
Within a municipality (relatively small town, admin level 8).<br>
<br>
We have manually identified and keep identifying the respective
waypoints we use for OSRM, about 100/hour, using OSM with open sat
tiles. Germany, Austria, Switzerland (example!!!) we talk about +150
hours work time for ~15 thousand waypoints.<br>
Now I thought about providing the improved data to OSM.

I also addressed before the issue of "nearest suitable road segment"
(see 17Aug16) also loosely related to this, where issues like
"national parks" popped up. Shopping centers jump to mind, "car free
city centers", etc, pp.<br>
<br>
In review, I understand that this is not a topic to the OSM people.
This is an issue for route planning people. Some implications must
be "sorted out".<br>
<br>
Question 1: Admin Center or maybe a new "Node ... as routing
waypoint" that we could add to polygons, such as airports, parks,
shopping centers, admin boundaries, etc. etc.<br>
I looked for Frankfurt Airport and got
<a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/search?query=Frankfurt%20Airport#map=13/50.0230/8.5446">http://www.openstreetmap.org/search?query=Frankfurt%20Airport#map=13/50.0230/8.5446</a>
leading to <a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/relation/5813621">http://www.openstreetmap.org/relation/5813621</a> (without
any node).<br>
I looked for Zurich Airport and got
<a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/search?query=Zurich%20Airport#map=14/47.4583/8.5482">http://www.openstreetmap.org/search?query=Zurich%20Airport#map=14/47.4583/8.5482</a>
leading to node <a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/node/26608880">http://www.openstreetmap.org/node/26608880</a><br>
Looking at Zurich <a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/relation/1682248">http://www.openstreetmap.org/relation/1682248</a>,
there is no admin center but "Node Zurich (240025182) as label".
Problem is, a "label" does not help. I believe we would need a "Node
Zurich (12345678) as waypoint". Wrong?<br>
<br>
Question 2: If you look at national parks or other "car free"
places, they may have multiple waypoints...?

Issue 3 (no question): A frequent and quick retort is "copyright".
For gawd's sake, we research the waypoints on OSM, what's the deal.
If any, WE have the copyright. But our idea is to return our
research under open source into OSM as a return for all the work OSM
(and OSRM) keeps saving us. There's more information we research and
adjust, I'm not afraid someone quickly copies our business model ;-)<br>
<br>
Question 4: TIME. For us, the issue is, we cannot justify manual
addition of those nodes to OSM. We can NOT invest a lot of time. We
can offer the data. I have no idea about how to add such a "node as
waypoint" or how to add those waypoints to the thousands of places
we have on file. Where NO admin center exists or the where the admin
center is causing issues with OSRM drive time calculations. I
imagine it easy for someone knowledgeable but still it takes time to
program even such routines (i.e. with basic checks such as not to
override existing waypoints). Happy to help. And to provide the
data.<br>
<br>
Should there be someone who has time and interest to help us adding
this large amount of data in a meaningful way into OSM for the sake
of the open community (and OSRM)... Please contact me at your
convenience.<br>
It's ongoing, we have not yet done them all... And maybe others may
contribute for other polygons...<br>
<br>
I think the main question is: Does someone have an idea how to add a
"node as waypoint" as a "standard" for any polygons into OSM???<br>
<br>
Best regards!<br>
