In the case of a median crossing (the third example in the original, and
the one I was commenting about earlier), I will make it a *_link instead
of service if it connects two service roads, so routing works as expected.

I tend to think of these as links.

The rule I've always followed is that it's the highest _link unless it's at an
intersection with a named street, in which case the names roads just
connect.

The only exception I think could make sense is if the *only *function of
the connector is to connect to a service road–like in a right-in/right-out
configuration– and U-turns aren't permitted. If the connector allows
U-turns on a dual-carriage arterial, then it ought to be a link so it has
the same priority in routing.

Thanks,

Andrew

I've been tagging those as *_link for years except on unclassified and
residential, which do not have a related *_link.

[Talk-us] Short 'connector' roads -- _link or not?

2018-11-20 Thread Martijn van Exel
Hi, 
As I was creating more ‘unnamed roads’ challenges in MapRoulette, and spot 
checking them, I came across a number of cases like this one:

https://maproulette.org/mr3/challenge/3313/task/6414594  

To my mind these need to be fixed, but I wanted to ask here first, so I can get 
the instructions right.  
Either such a segment is part of a 3 or 4 way intersection of higher class dual 
carriageway roads, in which case it should probably be named. 
Or as in this case, it is an extension of the service road, and it should be 
highway=service and remain unnamed like the service road itself.
..And I guess a third case is like https://www.openstreetmap.org/way/288576287 
, which should be a _link?

Advice welcome!

Martijn
