1. Why Transport and Communication Matter
Transport is the movement of people, goods and services from one place to another. Communication allows information to move without the physical movement of people.
- Production and consumption often occur in different places, so transport connects supply areas with demand areas.
- Transport, communication and trade are closely connected.
- A strong network of transport and communication supports local, national and international trade.
- Modern transport has greatly expanded the geographical reach of trade.
Main modes of transport
- Land transport — roads and railways
- Water transport — inland waterways and sea routes
- Air transport — airways
- Pipelines — mainly for liquids, gases and materials in slurry form
2. Roadways
India has an extensive road network. Roads are particularly useful because they can be constructed and maintained more easily than railway lines.
Why are roads important?
- Lower construction cost than railways.
- Can cross uneven and dissected terrain.
- Can handle steep slopes, including mountainous regions.
- Economical for short distances and smaller quantities of goods.
- Provide door-to-door service.
- Act as feeder routes connecting railway stations, ports and airports.
Classification of roads
| Type | Main function |
|---|---|
| Golden Quadrilateral & Super Highways | Connect major cities and reduce travel time/distance |
| National Highways | Connect major parts/extremities of the country |
| State Highways | Connect state capitals with district headquarters |
| District Roads | Connect district headquarters with other parts of the district |
| Other Roads | Connect villages and rural areas with towns |
| Border Roads | Provide connectivity in strategically important border areas |
The North–South Corridor connects Srinagar with Kanniyakumari, while the East–West Corridor connects Silchar with Porbandar. These projects aim to improve connectivity and reduce travel time.
Border Roads
The Border Roads Organisation (BRO) constructs and maintains strategically important roads in border regions. These roads improve accessibility in difficult terrain and also support economic development.
Metalled vs Unmetalled roads
- Metalled roads: made using materials such as cement, concrete or bitumen; generally usable throughout the year.
- Unmetalled roads: may become unusable during the rainy season.
3. Railways
Railways are a major means of transporting passengers and freight over long distances.
Importance
- Support the movement of goods and people.
- Encourage business, tourism and pilgrimage.
- Help integrate different parts of India.
- Support the growth of agriculture and industry.
Factors affecting railway distribution
Railway development depends mainly on:
- Physical factors: relief, rivers, mountains, deserts, forests and swamps.
- Economic factors: availability of resources and economic activity.
- Administrative factors: planning and regional requirements.
The Northern Plains provide favourable conditions because of their level land, high population and agricultural productivity. In contrast, mountainous, desert, swampy and heavily forested areas make railway construction more difficult.
Important fact
The first train in India travelled from Mumbai to Thane in 1853, covering about 34 km.
Railway gauges mentioned in the chapter
- Broad Gauge: 1.676 m
- Metre Gauge: 1.000 m
- Narrow Gauge: 0.762 m and 0.610 m
4. Pipelines
Pipeline transport is especially useful for transporting:
- Crude oil
- Petroleum products
- Natural gas
- Some solid materials after converting them into slurry
Advantages
- Initial construction cost is high.
- Running costs are low after construction.
- Reduces trans-shipment losses and delays.
- Makes it possible to supply inland refineries, power plants and fertiliser industries.
Important pipeline network
The Hazira–Vijaipur–Jagdishpur (HVJ) pipeline is an important cross-country gas pipeline mentioned in the chapter.
5. Waterways
Water transport is one of the cheapest modes of transportation.
Major advantages
- Suitable for heavy and bulky goods.
- Fuel-efficient.
- More environment-friendly.
- Useful for inland as well as international trade.
Important National Waterways
| Waterway | Route |
|---|---|
| N.W. 1 | Ganga: Prayagraj–Haldia |
| N.W. 2 | Brahmaputra: Sadiya–Dhubri |
| N.W. 3 | West-Coast Canal in Kerala |
| N.W. 4 | Parts of Godavari and Krishna system |
| N.W. 5 | Parts of Brahmani–Mahanadi system and East Coast Canal |
The chapter also identifies other waterways such as the Mandavi, Zuari, Sunderbans, Barak and Kerala backwaters.
6. Sea Ports
Ports are important gateways for international trade.
India has a long coastline and numerous major and non-major ports. A very large share of India’s foreign trade moves through sea routes.
Important ports and their special features
- Deendayal Port: important for trade serving a large northern and western hinterland.
- Mumbai Port: major natural and sheltered harbour.
- Jawaharlal Nehru Port: developed to reduce pressure on Mumbai Port.
- Mormugao: important for iron ore exports.
- New Mangalore: handles iron ore-related exports.
- Cochin: located at the entrance of a lagoon and has a natural harbour.
- V.O. Chidambaranar: important southern port with a natural harbour.
- Chennai: one of India’s older artificial ports.
- Visakhapatnam: deep, protected, landlocked port.
- Paradip: important for iron ore exports.
- Kolkata: inland riverine port; requires regular dredging because it is tidal.
- Haldia: developed to reduce pressure on Kolkata Port.
7. Airways
Air transport is the fastest mode of transport discussed in the chapter.
Advantages
- Saves considerable time.
- Can cross mountains, deserts, forests and long stretches of water.
- Especially useful for regions where roads and railways are difficult to develop.
Air transport is particularly valuable in the North-Eastern states, where difficult relief, rivers, forests and frequent floods can restrict surface transport.
UDAN
UDAN (Ude Desh ka Aam Nagrik) is a regional connectivity scheme intended to make air travel more accessible and encourage flights to regional and remote areas.
8. Communication
Communication allows information to be exchanged over distances without requiring physical movement of the communicator or receiver.
Main forms
- Personal communication
- Mass communication
- Postal services
- Telephone
- Radio
- Television
- Newspapers
- Films
- Internet and digital communication
The postal network handles both personal written communication and parcels. Different mail channels are used to improve delivery efficiency.
Mass communication
Mass communication reaches large numbers of people and serves two major purposes:
Entertainment + Awareness
Examples:
- Radio
- Television
- Newspapers
- Magazines
- Books
- Films
9. International Trade
Trade means the exchange of goods between people, regions, states or countries.
Types
- Local trade: within local areas.
- State-level trade: between two or more states.
- International trade: between different countries.
International trade may occur through sea, air or land routes.
Why is international trade necessary?
Countries have different resources and cannot produce everything they need. Therefore, they depend on exchange with other countries.
Exports and Imports
- Export: goods/services sold to another country.
- Import: goods/services purchased from another country.
Balance of Trade
Balance of Trade = Value of Exports − Value of Imports
- Favourable balance: exports > imports
- Unfavourable balance: imports > exports
India’s major exports mentioned
- Gems and jewellery
- Chemicals and related products
- Agricultural and allied products
- Information technology/software services
Major imports mentioned
- Petroleum crude and products
