Transport and communication are called the lifelines of a nation and its economy because they are essential for socio-economic progress. Despite India's vast size, diversity and linguistic plurality, these means have linked the country well with the rest of the world.

The movement of goods and services from supply locations to demand locations necessitates transport. Without efficient transport, products cannot reach consumers. The pace of development of a country depends not only on the production of goods and services but also on their movement over space.

A dense and efficient network of transport and communication is a prerequisite for local, national and global trade. Trades from local to international levels have added to the vitality of the economy. Transport, communication and trade are complementary to each other.

Modern means like railways, airways, waterways, newspapers, radio, television, cinema and internet have enriched our lives and added substantially to growing amenities and facilities for the comforts of life.

With the development in science and technology, the world has been converted into a large village through efficient and fast moving transport and equally developed communication systems. Thus, they serve as lifelines for modern economy.
