Transport and Communication

Lifelines of National Economy

In our daily lives, we use a variety of goods and services. Some of these are readily available in our immediate surroundings, while others must be brought from distant places. The movement of goods and services from their supply locations to demand locations is essential for fulfilling our needs. This movement is facilitated by transport, which is the physical transfer of goods and people from one place to another. Traders play a crucial role in this process by ensuring that products reach consumers through transportation. The pace of a country's development depends not only on the production of goods and services but also on their efficient movement across space. Therefore, having efficient means of transport is a prerequisite for rapid development. Transport operates over three main domains of the earth: land, water, and air. Accordingly, transport is classified into land transport, water transport, and air transport. However, transport alone is not sufficient; it requires an equally developed communication system to function effectively. Transport, communication, and trade are complementary to each other. India, despite its vast size, diversity, and socio-cultural plurality, is well linked with the rest of the world through railways, airways, waterways, newspapers, radio, television, cinema, and the internet. These means have contributed significantly to India's socio-economic progress. Trade, ranging from local to international levels, adds vitality to the economy, enriching life and enhancing amenities and facilities for comfort. This chapter explores how modern means of transport and communication serve as lifelines of the nation and its modern economy. A dense and efficient network of transport and communication is essential for local, national, and global trade today. Historically, trade and transport were limited to small areas, but advancements in science and technology have expanded their reach globally, transforming the world into a 'large village' through fast and efficient transport.

• Transport moves goods and services from supply to demand locations.
• Traders facilitate the movement of goods to consumers.
• Efficient transport is essential for a country's development.
• Transport is classified into land, water, and air transport.
• Transport, communication, and trade complement each other.
• India is well connected nationally and internationally through various transport and communication means.
• 📌 Transport: The movement of goods and people from one place to another.
• 📌 Communication: The exchange of information through various means.
• 📌 Trade: The exchange of goods and services between people or countries.

Roadways

India has the second largest road network in the world, totaling about 62.16 lakh kilometers as of 2020-21. Historically, roadways preceded railways in India and continue to have advantages due to their ease of construction and maintenance. The growing importance of road transport compared to railways is due to several reasons: (a) The construction cost of roads is much lower than that of railway lines. (b) Roads can traverse more dissected and undulating terrain. (c) Roads can negotiate higher gradients, allowing them to cross mountainous regions like the Himalayas. (d) Road transport is economical for transporting fewer persons and smaller quantities of goods over short distances. (e) It provides door-to-door service, reducing loading and unloading costs. (f) Roads act as feeders to other transport modes, linking railway stations, airports, and seaports. Roads in India are classified into six categories based on their capacity: 1. Golden Quadrilateral Super Highways: A major government project linking Delhi, Kolkata, Chennai, Mumbai, and back to Delhi through six-lane highways. It includes the North-South corridor connecting Srinagar and Kanniyakumari, and the East-West corridor connecting Silchar and Porbandar. The National Highway Authority of India (NHAI) implements these projects to reduce travel time and distance between mega cities. 2. National Highways: These link extreme parts of the country and form the primary road system, running mainly in North-South and East-West directions. 3. State Highways: Roads linking state capitals with district headquarters. 4. District Roads: Connect district headquarters with other places within the district. 5. Other Roads: Rural roads connecting villages and rural areas to towns, significantly developed under the Pradhan Mantri Grameen Sadak Yojana to ensure all-season motorable roads to every village. 6. Border Roads: Constructed and maintained by the Border Roads Organisation (BRO), established in 1960 to develop roads of strategic importance in northern and northeastern border areas. These roads improve accessibility in difficult terrains and aid economic development. Roads are also classified based on construction material into metalled (made of cement, concrete, or bitumen) and unmetalled roads. Metalled roads are all-weather, while unmetalled roads become unusable during the rainy season.

• India has the second largest road network globally (62.16 lakh km).
• Roads are cheaper and easier to build and maintain than railways.
• Road transport is flexible, economical for short distances, and provides door-to-door service.
• Roads are classified into Golden Quadrilateral, National Highways, State Highways, District Roads, Other Roads, and Border Roads.
• Border Roads Organisation builds roads in strategic border areas.
• Roads can be metalled (all-weather) or unmetalled (affected by rain).
• 📌 Golden Quadrilateral: A network of highways connecting four major metropolitan cities in India.
• 📌 Border Roads Organisation (BRO): Government agency responsible for constructing and maintaining roads in border areas.
• 📌 Metalled Roads: Roads constructed with cement, concrete, or bitumen, usable in all weather.
