Unnecessary announcements when driving a crooked road

[tegzed]

Hello ,

I have a navigation announcement related problem. If i drive along the following route with Navit:

​http://maps.google.com/maps?f=d&source=s_d&saddr=Budakeszi+%C3%BAt&daddr=47.528106,18.950293&hl=en&geocode=FWol1QIdeAohAQ%3B&mra=mi&mrsp=1&sz=15&sll=47.524562,18.946266&sspn=0.013302,0.038581&ie=UTF8&z=15

I get several unnecessary announcements. Removing the following two lines in navigation.c in function maneuver_required2() seems to solve the problem.

 1074                         if (is_same_street && is_same_street2(old->name1, old->name2, w->name1, w->name2) && (cat != 7 || wcat != 7) && is_way_allowed(w))
 1075                                 is_same_street=0;

I think however that my modification may affect correct behavior in certain cases. Maybe an additional filtering condition is required to the original condition to prevent setting is_same_street=0 in some situations which will make the maneuver required. Can anybody please review this condition to improve navigation on crooked roads?

Thanks, David Tegze

Our discussion with Cp15 revealed that this routing problem is caused by duplicate way data in osm database. I have removed the unnecessary way from osm and the problem disappeared. I close this ticket as invalid. Thanks for your help.
