Hello. Thanks for mapping on this project.
A remark about mapping highways
How to decide when a trace is a path or an unclassified highway
First, look what they connect.  Houses, settlements, villages. Then measure the width of that trace.
In iDeditor 

Shortcut : Ctrl+⇧ Shift+M – toggle  opens measurement panel
Draw a line between the shoulders of a trace (zoom in very far) and read the distance.
If a trace is max 2 meters wide, tag it as a path.
Wider and connect hamlets, houses and villages should be tagged as unclassified.
Tag residential in urban areas (villages, towns)
In JOSM, use the measure tab, or draw a circle (round building, shortcut Alt-Z when the building plugin is installed)) between the shoulders of a trace and read the distance on the lower toolbar. (remove the circle after that)

This is mentioned about tracks on the

Quote: Tracks are roads of agricultural purpose. They usually connect fields to farms. The surface sometimes makes them inaccessible for regular cars, or at least limits the speeds to a very slow pace. Tracks should always be avoided for through-going traffic or within urban areas.
All traces in farmland can be tagged as 'track' but is not essential on this project.
Important are roads connecting settlements, houses and villages.
Best regards and keep mapping
