Turn restrictions

Telenav follows the conventions for Turn Restrictions as described on the OpenStreetMap wiki. We use both 'simple' turn restrictions that follow the way-node-way pattern, as well as 'via' turn restrictions that use the way-way-[...]-way pattern as described on the wiki.

Telenav relies on route relations as the primary source for determining the road network and number (I-80, US-6, etcetera), following the conventions set out on the OpenStreetMap wiki page.
