[mkgmap-dev] [PATCH v5] - drive on left + roundabout direction checking

From Dermot McNally dermotm at gmail.com on Tue Oct 27 23:36:17 GMT 2009

I love the roundabout warnings and, with their help, I've been able to
fix all the broken roundabouts in Ireland that they have identified.

In the process, though, I've spotted a particular kind of false
positive that I suspect we can avoid. Consider this way:


Before I split this way, it went directly from the roundabout west as
N52, connecting in the process to the terriary road to its south
_which itself connects to the roundabout_. Neither road has flares
mapped for it. I got the following warning:

2009/10/27 23:20:25 WARNING (RouteNode): Incoming roundabout flare
road (N52, http://www.openstreetmap.org/browse/way/43100358) points in
wrong direction?

My interpretation is that, since these roads connect to the roundabout
and then to each other, they must be flare ways. My suggestion is that
there should be a certain reasonable maximum length within which flare
ways are expected to connect together, and that otherwise, they be
considered normal roads.
