[Talk-in] classification for rural roads

[Sunil K]

One peculiar problem I faced while mapping in kerala is the villages are 
spread out, there are usually no village centers. Also many cases there 
is no hard boundary to separate two panchayths or  even districts. Yes, 
there are hard boundaries for administrative purpose, but for most 
practical purpose there is only a blured line . So when I map in places 
not in my neighbourhood, it was always a problem. only think clear to me 
whether the road is wide enough to accomodate two vehicles or not.  In 
such scenarios mapping tertiary based on connective village centers may 
not be feasible.

Other think is many roads have a  lot of curves, steep inclines, though 
wide enough  average speed we can take in this roads are limited. Though 
they are good for small distances, best be avoided while  travelling 
long distances.
