Dear Sir, Do you comprehend simple logic? Any source (lets take Indian for your satisfaction) will give you detials about Indian highways…
You do not need to go around and list the names, you only need to know the coverage in term of percentage… Does it makes sense???..
Since you did not like the “exterior” source here is an Indian with same numbers..

The roads carry about 65 percent of freight and 86.7 per cent of passenger traffic. ** Although National Highways constitute only about 2 percent of road network it carries 40 percent of the total road traffic. **
