Transport and communication

  • Transportation is an organized service industry created to satisfy the basic needs of society. It includes transport arteries, vehicles to carry people and goods and the organization to maintain arteries and to handle loading, unloading and delivery. 

Transportation

  • Transportation is a service or facility designed for the movement of people and goods from one location to another, utilizing various means such as humans, animals, and different types of vehicles.
  • A network of several places (nodes) connected by a series of routes (links) forms a transportation pattern. This pattern can be expanded to encompass various types of links between points, facilitating mobility.
  • Transportation occurs across land, water, and air. Land transport includes roadways and railways, while water transport and air transport constitute the other two modes.

Modes of Transportation

  • The primary modes of global transportation—land, water, air, and pipelines—serve both inter-regional and intra-regional transport needs, catering to both passengers and freight (excluding pipelines).
  • The choice of a transportation mode depends on factors such as the type of goods and services to be transported, the associated transport costs, and the available modes.

Land Transport

  • The primary mode of transporting goods and services occurs over land. Initially, humans served as carriers, later supplemented by animals. 
  • The advent of railways played a pivotal role, opening up continental interiors for commercial activities such as grain farming, mining, and manufacturing, particularly in the United States of America (USA). 
  • Land transportation has evolved to include pipelines, ropeways, and cableways for the movement of liquids like mineral oil, water, sludge, and sewers.

Roadways

  • Road transport is considered the most cost-effective for short distances compared to railways. Developed countries boast universal access to high-quality roads, including motorways, autobahns (in Germany), and inter-state highways that facilitate swift movement. 
  • The global motorable road length is approximately 15 million km, with North America contributing 33%—a region with the highest road density and the largest number of registered vehicles. In terms of road length, the USA, India, and China rank first, second, and third worldwide.

Highways

  • Highways are metalled roads connecting distant places, designed for unobstructed vehicular movement. 
  • Typically, highways are 80 m wide, featuring separate traffic lanes, bridges, flyovers, and dual carriageways to ensure uninterrupted traffic flow. Developed countries establish extensive highway networks, linking every city and port town.
  •  North America exhibits high highway density, approximately 0.65 km per sq km, ensuring every place is within 20 km of a highway. Notable highways include the Trans Canadian Highway, the Alaskan Highway, the Pan-American Highway, and US Highway 20.

Distribution of Highways in the world

  • Europe, with a significant number of vehicles and a well-developed highway network, faces competition from railways and waterways.
  • In Russia, a dense highway network extends from the industrialized region west of the Urals, with Moscow serving as the hub. 
  • The Trans-Siberian Highway, ranking fifth globally, traverses Russia from the Baltic Sea to the Sea of Japan, covering a vast width of the country. Also known as AH6, it forms a grid of national highways and is a critical transport route in Russia.
  • The expansive road network includes remarkable routes that span thousands of kilometers, facilitating connectivity and transportation across various countries.
  • Trans-Siberian Highway Stretching over 11,000 km from St. Petersburg to Vladivostok, the Trans-Siberian Highway holds the distinction of being the longest continuous road within a single country.

 

China National Highway G010

  • China boasts an extensive highway system, with National Highway G010 spanning 5,700 km from Tongjiang in Heilongjiang to Sanya in Hainan. This highway traverses provinces like Heilongjiang, Jilin, Liaoning, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, and Guangdong.
  • China-Pakistan Economic Corridor (CPEC)  A strategic infrastructure project, CPEC covers a 3,000 km route connecting China's Xinjiang Uygur autonomous region to the Gwadar port in Balochistan, Pakistan. The bilateral initiative aims to enhance connectivity through highways, railways, pipelines, and various development projects.
  • Indian Highways India boasts an extensive highway network, with National Highway No. 44 (NH 44) being the longest, connecting Kashmir to Kanyakumari.
  • The Golden Quadrilateral (GQ) links major metropolitan cities, including New Delhi, Mumbai, Bangalore, Chennai, Kolkata, and Hyderabad.
  • African Highways In Africa, a notable highway links Algiers in Algeria to Conakry in Guinea. Additionally, the Algiers-Conakry Highway connects the two cities, providing crucial connectivity.
  • Australian Highways Australia features a well-connected highway system, with Australian Highway 1 spanning 14,500 km and connecting coastal areas. Stuart Highway, the longest in Australia, covers 2,834 km, linking Darwin in the Northern Territory to Port Augusta in South Australia.

Border Roads

  • International boundary areas often have border roads, essential for integrating remote communities with major cities and supporting defense efforts.

Railways 

  • Railways serve as a crucial mode of land transport for both goods and passengers. The railway network varies in gauge size, with Europe boasting one of the most dense rail networks globally, covering approximately 440,000 km.
  • Europe The first public railway line opened in 1825 between Stockton and Darlington in Northern England. Different countries adopt various gauges, including broad, standard, meter, and small gauges, with the standard gauge being prevalent in the UK. Europe's extensive rail network includes key railheads in London, Paris, Brussels, Milan, Berlin, and Warsaw, with Belgium having the highest railway density.
  • North America boasts one of the world's most extensive rail networks, accounting for nearly 40% of the global total. The densest rail network is found in the highly industrialized and urbanized East-Central USA and adjoining Canada.
  • South America's rail network is most concentrated in two regions: the Pampas of Argentina and the coffee-growing region of Brazil, contributing to 40% of the continent's total route length.
  • In Asia, the rail network is densest in the densely populated areas of Japan, China, and India. Notably, China's Xining to Lhasa route reaches an altitude of 4,000 m above sea level, with the highest point at 5,072 m.
  • Africa, the second-largest continent, has only 40,000 km of railways, with South Africa alone accounting for 18,000 km due to the concentration of mining activities in gold, diamonds, and copper.

Key African Rail Routes:

  • Benguela Railway: Angola to Katanga-Zambia Copper Belt.
  • Tanzania Railway: Zambian Copper Belt to Dar-es-Salaam on the coast.
  • Blue train: Cape Town to Pretoria in the Republic of South Africa.
  • Railway through Botswana and Zimbabwe: linking landlocked states to the South African Network.
  • Trans-Siberian Railway (9,332 km): Connects the Pacific coast in Russia (East) to St. Petersburg (near European borders) in the West.
  • Trans-Canadian Railway (7,050 km): Connects Halifax in the East to Vancouver on the Pacific coast, linking key cities like Montreal, Ottawa, Winnipeg, and Calgary.
  • Canadian National Railway: Canada's largest railway spanning approximately 32,831 km of track.
  • Union and Pacific Railway:
