Hi Gerd,
I will check that.

Hi WanMil,
the patch has an influence on the number of turn restrictions.
For a tile in northern Germany GPSMapEdit shows :
r2946 with --x-no-mergeroads: 264 (valid) turn restirictions, 22 invalid
r2946 with activated mergeroads : 264 (valid) turn restirictions, 22
invalid
r2946 with patch and --x-no-mergeroads: 264 (valid) turn restirictions,
22 invalid
r2946 with patch and activated mergeroads : *223* (valid) turn
restirictions, *25 *invalid
(The invalid turn restrictions are listed in the log. Those are the ones
that prohibit
to drive into the wrong end of a oneway road, but GPSMapEdit doesn't
care when
the turn restriction also forbids to walk into the road)
Do you think that this could be okay?

Subject: [mkgmap-dev] [PATCH] RoadMerger reverses roads
Attached patch improves the RoadMerger so that roads are reversed when
it is required to be merged with another road.
A small test increased the mergerate by 2% (avg. 17% => 19% road network
reduction).
Please check it. The p-road check is not yet implemented.
There are also some performance improvements possible which I will post
with the next patch version.
Unit tests may fail.

Hi Gerd,
Hi WanMil,
two points:
1) line 517 is obsolete:
mergePoints.add(end);
It just blows up the size of the list and processing time.
Yep.
I've found another important thing: the road merger can merge many more
ways when it reverses non oneway ways. This should be no problem so
let's do it :-)
I will post another patch.
