SUB TOPIC 1:  MEANING AND MODES OF TRANSPORTATION

Meaning of Transportation

Transportation can be defined as the movement of people, good and services from one geographical area to another either by land, water and air.

In the olden days, goods were transported using animals. However, the modern day transportation can be classified into 3, namely (i) Land transportation (ii) water transportation (iii) air transportation

Modes of Transportation

1. LAND TRANSPORTATION

Land transportation takes place on land. They include road transportation, rail transportation and specialized pipeline which is used to transport liquid materials

• Road Transportation

Road transportation involves the use of vehicles like cars, motor cycles, bicycles, and in very backward economies, animal like donkeys, cows, camel etc.

• Rail Transportation

The railway transportation consists of the use of locomotives and coaches that move on the gauges. There are 3 types of gauges namely; narrow, standard and broad gauge. In advanced countries, standard gauges are used which make it as one of the fastest means of transportation. Narrow gauge is meant for rugged topography while the broad gauge is for plain land.

1. Specialized land Transport

• Ropeways and cable ways

They are used as chain lift and cable cents. In Nigeria, it is used to transport coal in Enugu to Oji power station

• Pipeline: This is a means of transporting liquid materials such as crude oil from drilling stations to refineries. It is also used to transport water from dams to consumers.
• Power transmission: This is a method of transporting power from the power station to the consumers. A good example is the transmission of power from Kanji dam to all parts of the country using cables.
