plan
 Responsibility
 Of construction and maintenance of NH was assigned to
central government.
 Aim
 To provide 2 lakh km of surface road and remaining
unsurfaced roads, so that when this target is achieved the
total road length of 532700 km with density of about 16 km
of road length per 1000 sq. km area by end of 1963.
 Formula
 It is based on star and grid pattern of road network, but
the existing irregular pattern of road and obligatory points
not fitting in the geometric pattern were to be given due
consideration.

8. Silent feature of Nagpur road
plan
 Farthest point
 In developed and agricultural area within 8km of metalled road.
 In agricultural land Grid of 16 km so that the maximum distance
from the centre is 8 km and the avg. distance of the village from
metalled road would be less than 3.2 km.
 In non-agricultural area size of grid 64 km, farthest distance from
centre to metalled road is 32 km.
 Second category road
 They are meant to provide internal road system linking villages with
first category road.
 Rail way length
 Considered in deciding of 1st category road.
 15%
 Clearance for development (indus. & Agri.) during next 20 years.
