Telenav/Mapping Projects/Europe/Ingolstadt
To make OpenStreetMap more navigable and accurate in guidance, our mapping team started an editing project in Europe.We will focus on editing one ways, turn restrictions, road geometry and also validating the existing map by correcting keep right errors. We will start editing in Ingolstadt at the end of April.

One way from ImproveOSM:
We will review and add if necessary the oneway=yes tag on navigable roads after consulting the available data (OSM Oneway key).

Turn Restrictions from ImproveOSM:
We will use the following tags: -relations: type=restriction ; restriction= * ; except= * -relations: type=restriction ; restriction:conditional= * ; except= * -members:

Road Geometry:
To improve the existing data, we will focus on adding missing roads from valid sources.
We will follow the mapping scheme that is already used from the community: https://wiki.openstreetmap.org/wiki/Key:highway

How to map
We will be following the global OSM conventions alongside the ones specific for Germany, as they are described on these pages: https://wiki.openstreetmap.org/wiki/Attributierung_von_Stra%C3%9Fen_in_Deutschland https://wiki.openstreetmap.org/wiki/DE:Map_Features
