Life Lines of National Economy

Means of Transport - Movement

Image Shows Various Types of Transport

that՚s focusing on lifeline of national economics and that՚s basically the transport network, now when we classify the transport network we can say we either have land transport, water transport or air transport, now land transport could further be classified as either roadways, Railways and Pipeline.

Under water transport we have Inland water suppliers and overseas suppliers under airway you have either the domestic network or the international network. When I said domestic that means within the nations so you would have all the networks of air transport that is occurring within the nations, when I say international that means it would be beyond the country so you would have linkages internationally.

Now similarly water ways when we say inland this mainly focuses on the river base rivers that flow within the nation so you have inland navigation by means of Ganga, Brahmaputra, Krishna, Godavari, Narmada and Tapi so all these revering tracks would be kind of inland water transportation systems. When it comes to overseas it would come on to the peripheral area and the coastal area of India from where you can export and import the products. Again under land roadways, railways and pipeline are cleared by the name themselves. Now let՚s start with the first that is roadways.


  • Largest in world with 2.3 million km

Why roads are more feasible?

  • Cheaper construction rate
  • Can traverse dissected topography
  • On higher gradients
  • Economical
  • Door to door service
  • As feeder to other transport

Road Density (Length of road per 100 km2)

Now let start with the first is roadways, India has the largest roadways network in the world with nearly 2.5 million kilometers of road length that is ready. Now why roads are much more feasible than any other mode of transportation. The primary region is construction rate of roadways is cheaper, you can always traverse through roadways on a dissected topography, so it՚s easy to reach a remote area by means of roadways, again if there is very high or very steep gradient construction of roadways would be the easiest way for travel, construction of railways or pipeline would not be a kind of feasible mode in the area which has very steep gradient.

Roadways is most economical in terms of construction and the onetime cost and it can also provide door to door services, if you look on to the train network or the railway network it can only connect the metropolitans, so let՚s say it՚s connecting Mumbai to Delhi, but within Bombay if I want to reach on to the particular localities and the particular colonies the only way we can do through is the road network, so roadway is the only service that can provide you door to door service and again this roadways acts as a feeder for other transportation. so let՚s say I have container that comes on to the ocean from this container shipment I have to transport from Bombay to Delhi, so this container has to move from ship to train and this would be connected through road, so from ship it would go to road and from roadways it would go to the railways and finally it would be transported to Delhi, so it acts as feeder to other transport when we talk about the development in terms of road network we talk in terms of road density and what is that road density, what density is the length of the road that is available per 100 kilometers square of the area.
