The general wiki says:
„A frontage road (also access road, service road, parallel road, etc.) is a minor road running parallel to a higher-speed more major road, often in an urban setting.“
„Do not use the highway= tag for the frontage road. Simply use one of the normal highway=* tags. As the frontage road is less important than the major road, it must also have a lower highway=* tag than the major road“
The Indian wiki declare frontage roads similiary. (India/Tags/Highway - OpenStreetMap Wiki)
But the actual mapping of frontage roads parallel to NH trunks in India is not like this.
often highway=trunk is used
or trunk_link (which are meant only for slip roads/ramps)
in most cases frontage roads are mapped with oneway=yes: I am unable to decide, in which cases
this is correct. If they are mapped without oneway=yes, then it is possible to enter the trunk with a
- generally we have a problem in case of trunks with two carriageways: in these cases the
connecting roads are mapped, so that it is sometimes impossible to pass the trunk and reach the
other village part.
