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.
