To do: fix some nasty navigational errors in the nasty connection between Main North Road, Southern Expressway and Panalatinga road

Posted by freedomjosh on 6 December 2017 in English (English)

Previously all navigation methods on this route would recommend an illegal turn while heading north on Panalatinga to the right and then to the left, asking you to enter and leave trunk road and join another.

I made some no turns and it filtered out most navigations, but GraphHopper is still suggesting the illegal route:

Location: Aberfoyle Park, City of Onkaparinga, South Australia, 5159, Australia

It may take some time to GraphHopper, OSRM and others update their database.

GraphHopper and other navigators needs to first download a copy of the OSM database and then process the data into special formats suitable for their purpose. This process can be quite computing intensive and that's why you should expect navigators to take at least a day (some much longer) to pick up changes to the OSM database.
