Re: [Talk-us] US 221 (NC) Median U-Turns

[Martijn van Exel]

UDOT loves them too. Like here: 
https://www.openstreetmap.org/#map=18/40.68178/-111.98131 

Also we love diverging diamond interchanges around here:

https://www.openstreetmap.org/#map=17/37.10968/-113.55576 

So much so that UDOT has a 60 page document about them including Arthur Miller 
quotes: http://www.udot.utah.gov/main/uconowner.gf?n=14769524027177477

That is called a "Superstreet" [1]. NC seems to love these, as I've seen it pop 
up alone NC-73 recently near it's interchanges with both I-77 & I-85.

This is just a new road configuration (to me).   NC Onemap aerials
updated to show the latest road configuration after they expanded 10
miles of dual carriageway on US221 in NC.   They used Median U-turn
configurations along the length rather than straight cross traffic for
the crossroads

OSRM shows the routing

These are based off of Lambertus's work here:

http://garmin.openstreetmap.nl

free to ask.  However, please do not send me private mail.  The
odds are, someone else will have the same questions, and by
asking on the talk-us@ list, others can benefit.

FAQ



Why did you do this?

I wrote scripts to joined them myself to lessen the impact
of doing a large join on Lambertus's server.  I've also
cut them in large longitude swaths that should fit conveniently
on removable media.  

http://daveh.dev.openstreetmap.org/garmin/Lambertus/2016-04-22

Can or should I seed the torrents?

Yes!!  If you use the .torrent files, please seed.  That web
server is in the UK, and it helps to have some peers on this
side of the Atlantic.

Why is my map missing small rectangular areas?

There have been some missing tiles from Lambertus's map (the
red rectangles),  I don't see any at the moment, so you may
want to update if you had issues with the last set.

Why can I not copy the large files to my new SD card?

If you buy a new card (especially SDHC), some are FAT16 from
the factory.  I had to reformat it to let me create a >2GB
file.

Does your map cover Mexico/Canada?

Yes!!  I have, for the purposes of this map, annexed Ontario
in to the USA.  Some areas of North America that are close
to the US also just happen to get pulled in to these maps.
This might not happen forever, and if you would like your
non-US area to get included, let me know.
