INTRODUCTION

Importance of transportation :

Role of transportation:

Transportation contributes to the economic,industrial, social and cultural development of any country. Transportation is vital for the economic development of any region since every commodity produced whether it is food,clothing, industrial products or ! medicine needs transport at all stages from production to distribution. In the production stage , transportation is required for carrying raw materials like seeds , manure, coal, steel, etc. In the distribution stage, transportation is required from the production centres viz. farms and factories to the marketing centres and later to the retailer's and consumers for the distribution. The inadequate transportation facilities retard the process of socio economic development of the country. The adequacy of transportation system of a country indicates its economic and social development.

Economic activity and transport :

The economic activities are the processes by means of which the products are utilised to satisfy the human wants. Two important factors well known in economic activity are

I. Production or supply

II. Consumption for human wants or demands

Man and his products are thus not bound to his local surroundings. The importance of transportation in economic activity is to be found in its effect on both humans wants for goods and satisfaction through production and distribution. While discussing the general effects of transportation, it may be said that the increased productivity and it's efficient transportation can lower the cost of the products. The transportation cost is always an influencing factor on consumer price of commodities.

Social effects of transportation :

Progress follows the the lines of transportation. Population have always settled along with the rivers shores, road sides and near railway stations. In the present concept of transportation network, this kind of ribbon development is greatly discouraged. Attempts are being made to decentralise the population centres away from the sides of the main transportation routes. Thus town planning patterns are rapidly changing. To avoid congestion around the populated areas across suburban living and industrial enterprises are developing. These suburbs and satellite towns acting as counter  magnets should be linked up with rapid transit systems. The various social effects of transportation may be further elaborated as :

a. Sectionalism and transportation : Improved transportation has important implication in reducing sectionalism within the country and also outside the country.

b. Concentration of population into urban area : The I transportation network brings prosperity to the urban population.

c. Aspect of safety, law and order : Transport facilities are essential for rushing aids to areas affected by an emergency.

All the advantages of transportation can be summarised as :

i Transportation is for advancement of the community

ii Transportation is essential for the economic prosperity and general development of the country

iii Transportation is essential for strategic movements in emergency for defence of the country and to maintain better law and order.
