Understanding Basic Terms Used in Freight Transport

We often hear about transport, but what exactly is it? Transport, in simple terms, is the transfer of objects, animals, humans, and even products from one place to another. In simple terms, the act of transport is described as any act of movement of something from a source A to a destination B. This can include air travel, ocean travel, land transportation, and road transportation. Transporting refers to the movement from one point to another and it happens every day. Transport is an essential activity for everyone, and since transportation has many uses, it has also created numerous industries.


For the purposes of this discussion we will only consider transport on land. Land transport can be categorized into two major forms: vehicle transport and railroad transport. Vehicle transport refers to the movement of people, material, and products by means of vehicles. Rail transport, however, refers to the movement of material and people by railroads. Both of these commonly used forms of transport are affected by the environmental factors that affect the transportation of goods from one place to another.

On a closer look, vehicle transport can be divided further into three categories: public transportation such as trains, subways, and buses, private transportation such as taxis and motor cycles, and agricultural transport which include horse drawn carriage, air transport, railroad freight, and road transportation. Public transportation is mostly found on highways. Public subways and buses are commonly located at the entrances of cities. The railway freight runs between ports and cities. As for the agricultural transport, it mainly involves the movement and delivery of foodgrains.

To better understand the transport process, it is first important to have an idea of the different types of transport. Each type has its own characteristics that contribute to its efficiency and performance. When materials are transported from one place to another, they undergo what is known as the movement. This means that they are pushed or pulled by some force. The intensity and the direction of the force to determine how the materials are moved across the ground.

The two major categories of active transport using energy are gravity and surface tension. Gravity transport refers to the changes in the concentration gradient as the weight of the particles increases or decreases. For instance, when two rocks are placed on the same level, the weight of the rock on the downhill side will eventually decrease because of gravitational force. Because of this law of nature, the downhill rock will fall due to gravitational pull. However, when the two rocks are placed at different levels, the rock that experiences less weight will slide down and the uphill rock will continue to move upwards because of surface tension.

Another form of transport is passive transport. In this type, the energy is not used to move the substance and therefore, there is no change in concentration gradients. However, unlike gravitation transport, energy is required to move across a membrane. In this case, the substance is not moved across a barrier but instead, the barrier forms a permeable membrane between the substance and the carrier.

Some types of transport mentioned above also use one place for the transportation of a substance while in another place another substance is being transported. This is an example of strong emotion transport. Strong emotion transport can be used to move a hazardous chemical, radioactive material or radioactive waste across locations where access would be difficult or impossible. In the context of hazardous material, this means that the hazardous cargo needs to be moved under the most protected conditions so that it does not present a health hazard to people while it is being transported. Strong emotion transport makes use of a forklift and is done through trucking companies.

All of the main article modes of freight transport can be classified into two broad categories which include passenger transportation and non-passenger transportation. Each category has its own set of characteristics and features. The main article mode of cargo transport includes air transport, land and sea transport, rail transport and courier modes. There are other important modes of transport like delivery, refrigerated warehousing and telecommunication as well.
