Third Twenty Year Road Development Plan (1981-2001) (Lucknow Plan)
It was finalized and the plan document was published by the year 1984. The major objectives are:
i) The future road development should be based on the revised classification of road system consisting of Primary, Secondary and Tertiary road system.
ii) The road network should be developed so as to preserve the rural oriented economy and to develop small towns with all the essential facilities.
iii) All the villages with population of 500 should be connected by all weather roads.
iv) The overall density of road is increased to 82km per 100 sq.km
v) The NH network should be expanded to form square grids of 100 km sides so that no part of the country is more than 50 km away from NH.
vi) Expressway should be constructed along major traffic corridors to provide fast travel.
vii) Roads should also be built in less industrialized areas the attract the growth of industries.
viii) Long term master plans for road development should be prepared at various levels.
ix) All towns and villages with population over 1500 should be connected by Major district Roads and villages with population 1000 to 1500 by ODR.
x) There should be improvements in environmental quality and road safety.

Formulae
i) Length of NH (km) = area of the region/ 50

ii) Length of SH (km)
a. By area, SH (km) = area of the region/ 25
b. Based on no. Of towns, SH (km) = 62.5 x no. Of towns – NH
Adopt length of SH (higher of the two criteria)

iii) Length of MDR, in the District
a. Based on area, MDR (km) = area of the region/12.5
b. Based on number of towns, MDR(km) = 90 x number of towns
Provide length of MDR (higher of the two criteria)

iv) Total length of all categories of roads may be assumed to provide an overall density of road length equal to 82km per 100 sq.km area by the year 2001.
NH + SH + MDR + ODR + VR (km) = area of the region x (82/100)
Therefore length of ODR + VR (km) = Total Length – (NH + SH + MDR)

Fourth Twenty Year Road Development Plan (2001-2021) Vision: 2021
It is to be recognized that even after the habitations eligible under PMGSY are fully covered. There is still left with a large number (about 1.68 lakh) unconnected habitations of lower size population. To serve the last person and the remotest village. IRC and Ministry of Rural Development have decided to formulate a 20 year vision (May 2007) covering various aspects related to rural areas and it‟s dovetailing with the higher categories of roads and the urban landscape.

Objectives
i) The road network as on May 2007 stands at 3.3 million km. Of this, rural roads comprise around 2.7 million km, i.e. about 85 percent. Overall village accessibility stood at 54 percent in the year 2000.
ii) Emphasis is continuing in social development sectors so as to improve the quality of life and alleviate poverty
iii) The objective has to be to provide full connectivity to all habitations including provision of bridges and culverts. Accordingly, the following vision for new connectivity has been recommended.

a) Habitations with population above 1000 (500 in case of hill, NE states, deserts and tribal areas) by the year 2009-10
b) Habitations with population above 500 (250 in case of hill, NE states, deserts and tribal areas)by year 2014-15
c) Habitations with population above 250 by the year 2021-22
iv) The Central Government has also introduced the concept of a Core Network, which is defined as the network that is essential to provide one basic access to each habitation.
v) Proper drainage and design standards were made for rural roads .Many management rule, powers to different authorities and other standard data book was set and prepared by NRRDA (National Rural Road Development Authority).
vi) Importance was given to the use of advanced and latest equipments in road constructions to facilitate the economics.
vii) The Government also needs to develop independent think-tanks and academicians on various aspects of rural roads like engineering, safety, environmental issues, socio-economic impact, etc
viii) Action should be taken by each state to formulate a 5-year Action Plan in the light of recommendations of the Vision document.

Salient Features of Vision  2021
i) The Road Development Plan Vision: 2021 was prepared with the full involvement of the highway profession both within the government and the private sector and represents an expression of the intent for highway development in the two decades from 2001.
ii) This Vision addressed concerns such as the need for mobilization of financial resources including augmentation of road fund, toll financing, private sector participation, capacity augmentation of main highways, strengthening of pavement to cope with movement of heavy commercial vehicles, undertaking massive program me of construction of village roads and preservation of existing road assets.
iii) Aspects such as road safety, social and environment concerns and energy efficiency have also been highlighted.
iv) The vision document laid down targets for main roads but did not specify the length of the rural road network. Instead, stress was laid on preparation of proper district level master plans to optimize the network.
v) Target Roads Lengths by the year 2021:

a. Expressways 10,000 km
b. National Highways 80,000 km
c. State Highways 160,000 km d. Major District Roads 320,000 km
