The development of any region is not solely dependent upon the availability of raw material and production of finished goods but also the movement of raw material and finished goods over space. This movement can be done via three domains of the earth: 1. Land, 2. Water and 3. Air.

There are five major transport systems that can be found in any region. These are 1. Roadways, 2. Railways, 3. Airways, 4. Waterways, and 5. Pipelines.

As of 2015, the Indian road network stands at 54.7 lakh km, making it the third largest road networks after the United States and China. In India, roads are more preferred than railways because of the following reasons
1. roads are cheaper to build and maintain than railways
2. roads can provide access to undulating regions
3. roads can work on the higher gradient of slopes in mountainous areas such as the Himalayas
4. roads are economical in short length transports
5. roads provide door-to-door service, thus saving time and cutting the cost of loading and unloading material
6. roads provide linking service between railway stations, air and seaports.

In India, roads are classified into six different categories. These are

1. Super Highways
  1. These are 6 lane expressways linking megacities of India with the aim to reduce the travelling time between them.
