Hi Ronny,<br><br>I think the Dau work you did is overkill.<br><br>While conceptually, each toll booth slot is a separate way, I don't think the separation is long enough that they merit separate ways.<br><br>Also a correction, the barrier=toll_booth tag should be on nodes on the highway=* way, not on the building=yes way and it should be an underscore, not a space character.<br>
<br>I've only done two tollbooth mappings in OSM ever. The first one is the Coastal Road toll plaza in Paranaque: <a href="http://openstreetmap.org/?lat=14.48796&lon=120.98227&zoom=17&layers=B000FTF">http://openstreetmap.org/?lat=14.48796&lon=120.98227&zoom=17&layers=B000FTF</a><br>
<br>It's basically just two ways in opposite directions following the outermost lanes. But check out the data or T@H layer and you can see that I've added two additional closed highway=* ways with area=yes to signify that there is a considerable widening in the road (that can't be captured effectively by just lanes=* tags). I'm not sure if what I did is acceptable but at least it's still routable yet simple. The data still needs two barrier=toll_booth nodes there. Note that this setup ignores the fact the the middle N lanes can be configured to accommodate traffic in both directions so that the toll plaza can adjust depending on traffic conditions.<br>
<br>The second I did is the SLEX Sucat exit: <a href="http://openstreetmap.org/?lat=14.453638&lon=121.045358&zoom=18&layers=B000FTT">http://openstreetmap.org/?lat=14.453638&lon=121.045358&zoom=18&layers=B000FTT</a><br>
<br>Here I haven't placed any building outlines.<br><br><br>As for roundabouts, unles there are islands that separate the way going into the roundabout, topology dictates that the way should go straight into the roundabout unsplit.<br>

I'm fixing some things on NLEX, but I'm not so familiar in this area<br>
(apart form driving past there numerous times).<br>
Is this the Bocaue toll barrier?<br>

I'm assuming this is Balintawak toll barrier:<br>

<br>
I was playing around a bit with the Dau Toll Barrier, but I'm beginning<br>
to think I might have made a bit too much of an effort here:<br>
<a href="http://www.openstreetmap.org/?lat=15.17075&lon=120.60918&zoom=16" target="_blank">http://www.openstreetmap.org/?lat=15.17075&lon=120.60918&zoom=16</a><br>
<br>
Is there any recommendation for how to deal with issues like this:<br>
- what do we call them (toll gates/barriers/booths)?<br>
- how to tag them so that GPS navigators will deal with them in a<br>
sensible way?<br>
- is it a goo idea to do like I did in Dau, extending the one way path<br>
tagged "lanes=2" into however many lanes there are in the toll gate, or<br>
is it better to keep it a single path and just tag it "lanes=n" instead,<br>
positioning the path approximately in the middle?<br>
<br>
The same goes for roundabouts. I've been quite accurate when making<br>
them, letting the roads leading in and out enter the roundabout the way<br>
the traffic normally flows (or is supposed to flow, if anybody were<br>
following the rules), splitting them in two tiny one-way streets to show<br>
the exact flow of the traffic in and out of the roundabout.<br>
Is this a waste of time?<br>
Should I rather just let the road go straight into the roundabout<br>
without splitting it?<br>
Examples:<br>

I'm trying to make the map usable for GPS navigation, but I'm not sure<br>
if this is the best way to achieve that.<br>
Any advice is appreciated.<br>
<br>
Ronny.<br>
