<br class="">
more precise:<br class="">
<br class="">
<div class="">> prepare.minOnewayNetworkSize = 1</div>
<div class="">> prepare.minNetworkSize = 1<br class="">
<br class="">
this both can be 200 and will remove all disconnected
roadnetworks with less than 200 nodes.<br class="">
<br class="">
<div class="">> index.highResolution=10000</div>
<div class="">> index.maxRegionSearch=10000<br class="">
<br class="">
this is not so good. For maximum speed use e.g.<br class="">
<br class="">
<div class="">> index.highResolution=100</div>
<div class="">> index.maxRegionSearch=4<br class="">
<br class="">
For max 'fault tolerance' use:<br class="">
<br class="">
<div class="">> index.highResolution=1000</div>
<div class="">> index.maxRegionSearch=8<br class="">
<br class="">
which will search approx 1000m around the query AND try
around this location until it reaches roughly 8*1000m!<br class="">

Hi!
<div class="">I have encountered a problem in finding
routes between a few number of addresses. Most work
well, but it seems like some addresses on one way
streets and in areas with restricted access it fails
to find a route. I have implemented a quick-fix for
this by adjusting the coordinates in a outgoing
spiral until a route is found. But this is not a good
solution in densely populated areas, so, is there any
better solution?</div>
<div class=""><br class="">
</div>
<div class="">Hopefully, I’m simply doing something
wrong by getting this problem, as I do not get the
same problem on the test-server:</div>
