CHAPTER 3. ROLE OF TRANSPORTATION IN SOCIETY NPTEL May 7, 2007 Chapter 3
Role of transportation in society
Transportation is a non separable part of any society. It exhibits a very close relation to the style of life, the range and location of activities and the goods and services which will be available for consumption. Advances in transportation has made possible changes in the way of living and the way in which societies are organized and therefore have a great in uence in the development of civilizations. This chapter conveys an understanding of the importance of transportation in the modern society by presenting selected characteristics of existing transportation systems, their use and relationships to other human activities. Transportation is responsible for the development of civilizations from very old times by meeting travel requirement of people and transport requirement of goods. Such movement has changed the way people live and travel. In developed and developing nations, a large fraction of people travel daily for work,shopping and social reasons. But transport also consumes a lot of resources like time,fuel, materials and land. 3.2 Economic role of transportation
Economics involves production, distribution and consumption of goods and services. People depend upon the natural resources to satisfy the needs of life but due to non uniform surface of earth and due to di erence in local resources, there is a lot of di erence in standard of living in di erent societies. So there is an immense requirement of transport of resources from one particular society to other. These resources can range from material things to knowledge and skills like movement of doctors and technicians to the places where there is need of them.
3.2.1 The place, time, quality and utility of goods
An example is given to evaluate the relationship between place, time and cost of a particular commodity. If a commodity is produced at point A and wanted by people of another community at any point B distant x from A, then the price of the commodity is dependent on the distance between two centers and the system of transportation between two points. With improved system the commodity will be made less costly at B. 3.2.2 Changes in location of activities
The reduction of cost of transport does not have same e ect on all locations. Let at any point B the commodity is to be consumed. This product is supplied by two stations A and K which are at two di erent distances Introduction to Transportation Engineering 3.1 Tom V. Mathew and K V Krishna Rao

• Transport extends the range of sources of supply of goods to be consumed in an area, making it possible for user to get resources at cheap price and high quality.
• The use of more e cient systems of supply results in an increase in the total amount of goods available for consumption.
• Since the supply of goods is no longer dependent on the type of mode, items can be supplied by some alternative resources if usual source cannot supply what is needed. 3.3 Social role of transportation
Transportation has always played an important role in in uencing the formation of urban societies. Although other facilities like availability of food and water, played a major role, the contribution of transportation can be seen clearly from the formation, size and pattern, and the development of societies, especially urban centers. 3.3.1 Formation of settlements
From the beginning of civilization, the man is living in settlements which existed near banks of major river junctions, a port, or an intersection of trade routes. Cities like New York, Mumbai and Moscow are good examples.
