The Cargo Traffic: The commodity transport is dependent upon the world trade. The carriers differ with the size of cargoes, their weight and their volume. The light and perishable commodities are transported through the airways. For example, the jasmine flowers harvested in the districts of Erode and Dharmapuri are transported by the trucks to the nearby Bangalore. The flowers are then sent to the Gulf countries, immediately from there. Likewise, vegetables and meat are being sent to the Gulf countries from most parts of the country. Heavy commodities are sent through roadways and sea routes while the liquids and gases are being sent through the pipelines.
The vehicles or carriers are structured according to the nature of commodities. They are sent mostly through tankers (oil) and containers for safety.
In recent times, a new method of transport of cargoes has been in vogue. This is what is called the 'containerisation' of cargoes. In this method, all commodities are put into the containers and sent as contained cargoes. This is safe and more compact for transport. These containers are often transported by roadways to the ports. You may have seen the trucks and lorries that carry them. Finished products and consumer products are often sent through containers. Not only in the case of ports, but also in the transport of commodities in the interior of the country, the containers are very useful, in the export and import.
The commodities so transported are taxed at the origin of commodities traffic and then sent to the customers or consumers. In this method of cargo traffic, various products from several customers are placed into one and the same container and are then transported to the ports, after due precautions for safety by sealing and fastening. The containers are then exported to the overseas markets. Similarly, the containers are transported to the interior locations as they were received from the imports. They are mostly transported by land transports. The customs and excise officials levy taxes for some of these commodities before they are delivered to the addressees.
There are some merits to this form of transport:
1. Commodities are carried safely from the interior locations and cities to the ports.
2. Transport costs are reduced by sending the commodities from several exporters in the same containers.
3. The exporters and the importers could perform their exporting and importing functions from their own places of residences.
4. In loading the commodities onto the ships, containers help with large quantities being contained for export or import.
Liquid commodities such as milk, water and petrol are being transported in the cylindrical tankers. They are taken to many places on the roads and rails. Petroleum and natural gases are transported to the ports and refineries through the pipelines. Efforts are underway to transport grains through the pipelines using pressure as a force for moving.
We have grown to such an extent that we could be proud of our scientific knowledge and skill. In both scientific learning and corresponding technological gadgetry, we have forged ahead to a large extent. From the researches we have undertaken on the solar system and the planetary dynamics, we have been able to receive clear and intelligent information from the telecommunication equipment through technological advancements. As we have understood the import of telecommunication development, we have moved forward, step by careful step. We have thus developed new techniques. As the lilies multiply in a pond, quickly, so does our knowledge through the use of these techniques and equipment.
In the last few years, the diffusion of human knowledge has occurred as never before. This has been possible primarily because of the telecommunication links. With the technological development, books were published. These books helped with the education of most people. Newspapers, radios and television and such communication devices unite almost all the people in the world today.
