[jharpster]

We've identified a number of invalid turn restrictions across Australia. Many of these are quite old and just need to be cleaned up.

This task aims at improving the overall coverage of Turn restrictions in Australia and fixing specific invalid turn restrictions. Using available mapillary imagery, ortho imagery and probe data we will look at road markings and other indications to confirm if turn restrictions or mandatory traffic flows exist on a case by case basis across all of AU. Improvements should cover the following:
• Mandatory traffic flow directions.
• Adding turn restriction relations.
• Correcting any road alignment at junctions.
• One off fixes.
Mapping guidelines:
The mapping team will follow the OSM guidelines and Australia specific guidelines.
Tools:
JOSM will be the primary editing tool, and the turnrestrictions plugin.
