Chapter overview

Transport and communication connect places and people and support trade and development. The main modes of transport are roads, railways, water transport, airways and pipelines, each with advantages for particular goods and distances. Communication has been transformed by telecommunications, satellites and the internet. This chapter covers both the world pattern and India's transport and communication network.

World transport

  • Roads are best for short distances and door-to-door service; major highways include the Trans-Canadian Highway and the Pan-American Highway.
  • Railways carry bulky goods over long distances; transcontinental railways include the Trans-Siberian, Trans-Canadian and Union and Pacific railways.
  • Water transport is the cheapest for heavy, bulky goods; major sea routes include the North Atlantic route, the Suez Canal (1869) route and the Panama Canal (1914) route; inland waterways include the Rhine and the Great Lakes–St Lawrence seaway. Air transport is fastest; pipelines carry oil, gas and water.

Transport in India

  • India's roads include National Highways (built and maintained by the central government), State Highways, district and rural roads; the Golden Quadrilateral links Delhi, Mumbai, Chennai and Kolkata, and the North–South and East–West corridors link Srinagar–Kanyakumari and Silchar–Porbandar.
  • Indian Railways is one of the largest railway networks in the world, using broad, metre and narrow gauges, with ongoing gauge conversion and dedicated freight corridors.
  • India has National Waterways such as NW-1 on the Ganga (Haldia–Prayagraj); major ports include Mumbai, Jawaharlal Nehru, Kandla, Paradip, Visakhapatnam, Chennai and Kolkata–Haldia; air transport is managed by the Airports Authority of India; oil and gas pipelines include the Hazira–Vijaipur–Jagdishpur (HVJ) pipeline.

Communication

  • Personal communication includes post, telephone and the internet; mass communication includes radio, television, newspapers and films.
  • Satellites, such as India's INSAT and IRS series, support communication, weather forecasting and resource mapping.
  • The internet and mobile phones have greatly expanded access to information and services in India.

Key terms

Suez Canal
a canal linking the Mediterranean Sea and the Red Sea, opened in 1869
Trans-Siberian Railway

Important questions with answers

What is the importance of pipelines?2 marks

Pipelines transport liquids and gases such as crude oil, petroleum products, natural gas and water over long distances continuously and cheaply, with little loss and without disruption from weather. In India, the Hazira–Vijaipur–Jagdishpur pipeline supplies gas to fertiliser and power plants.

What are the advantages and disadvantages of water transport?3 marks

Water transport is the cheapest for carrying heavy and bulky goods over long distances, needs no track construction except ports and is fuel-efficient. However, it is slow, depends on navigable waterways and ports, and inland waterways may be affected by seasonal changes in water level.

Describe the transport network of India.5 marks

India has a large and diverse transport network. Roads carry the largest share of passengers and goods; they include National Highways built and maintained by the central government, State Highways, district roads and rural roads, many of them built under the Pradhan Mantri Gram Sadak Yojana. Major projects include the Golden Quadrilateral linking Delhi, Mumbai, Chennai and Kolkata, and the North–South corridor from Srinagar to Kanyakumari and the East–West corridor from Silchar to Porbandar; expressways are also being built. Indian Railways is one of the largest rail networks in the world; it uses broad, metre and narrow gauges, with most lines being converted to broad gauge, and it carries bulky goods such as coal, ores, food grains and fertilisers; dedicated freight corridors and high-speed rail projects are being developed. Water transport includes inland waterways such as National Waterway 1 on the Ganga, NW-2 on the Brahmaputra and NW-3 in Kerala, and a long coastline with major ports such as Mumbai, Jawaharlal Nehru Port, Kandla (Deendayal), Mormugao, New Mangalore, Kochi, Tuticorin, Chennai, Visakhapatnam, Paradip and Kolkata–Haldia. Air transport is provided by public and private airlines, with airports managed by the Airports Authority of India. Pipelines carry crude oil, refined products and natural gas, such as the HVJ pipeline. Together these modes integrate the national economy.
