I have used <br>> default style, car/motorcycle routing, fastest route. I can confirm, <br>> that both version show a detour on Polish road 6. It seems to depend on <br>> many factor so it is difficult to isolate a meaningful example.<br>> <br>> Some notices:<br>> <br>> In Mapsource route depends on "Road selection" option in route <br>> preferences. I usually set it in the middle but when set to 75% of <br>> "Prefer Highways", routing becomes better.<br>> <br>> For nod127 branch there is difference in routing, when I set avoidances <br>> to unpaved road. It doesn't clear the problem, only detour is different.<br>> <br>> In BaseCamp I got the same detour in both version of mkgmap. For nod127 <br>> detour changes, when I set avoidance to unpaved road, no change in <br>> trunk. In both version detour changes the same way if I set avoidances <br>> to residential streets. Any of highway avoidances changes detour and <br>> when I use avoid State Highways, route is correct. I'm not sure what is <br>> "State Highway" for BaseCamp, it could be primary road, which actually <br>> is used for route.<br>> <br>> BaseCamp is not able to calculate longer route with trunk, the same <br>> route is calculated with nod127 (including detour).<br>> <br>> Please write if you have any suggestion what could I test or what data <br>> could be useful for you.<br>> <br>> -- <br>> Best regards,<br>> Andrzej<br>> _______________________________________________<br>> mkgmap-dev mailing list<br>> mkgmap-dev@lists.mkgmap.org.uk<br>> http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev<br></div> </div>
