MOTOR CARRIER

Motor carrier is also known as road or land transportation.It is divided by two type which are for-hire and private carriers.

RAILROADS

Rail transport is a means of conveyance of passengers and goods, by way of wheeled vehicles running on rails. It is also commonly referred to as a railway train transport.

AIR CARRIER

Air carrier is an organization or company that transporting passengers and cargo by aircraft.They are also known as airlines.

WATER CARRIER

Water carrier also known as shipping industry have evolved in today's market into three separate but closely connected segments which are bulk shipping, liner shipping and specialized shipping. Although these segments belong to the same industry, each carries out different tasks and has a very different character.

PIPELINES

Pipeline is direct channel by which privately transmitted especially for the conveyance of water, gas, or petroleum products.It is also one of the modes of transportation and it is not highly used in our country as other modes of transport.

Issues In Transportation Nowadays

Nowadays, cities that locate at the high level of people on that surround area mostly need support by transport system. The larger the city, the greater its complexity of the transport system structures. Additionally, important transport terminals such as ports, airports, and rail terminal are located within urban areas and they contributing to a specific type of problems. The most important transport problems are often related to urban areas and it is because of many reasons:

CONGESTION


The obvious problem that we can see is congestion. Whether it is the vehicle or the people that need the transport, both have the same problem which is congestion. The demands of the transport are increasing day by day, however the infrastructure are not been able to keep up with the growth of the demand. Even though the innovations are rapidly increased, but still it doesn't help the transportation structures that much. During peak hours, crowdedness creates discomfort for users because of surge in demand. Moreover, even the highway can be full of vehicle, this will lead to unnecessary accidents and because of this it will double the number of the vehicle on the road and it will make a terrible traffic congestion.

ENVIRONMENTAL EFFECT

Pollution, including noise, generated by circulation has become a serious impediment to the quality of life and even the health of urban populations. Further, energy consumption by urban transportation has dramatically increased and so the dependency on petroleum.The environmental impact of transport is significant because it is a major user of energy and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and is a significant contributor to global warming through emission of carbon dioxide, for which transport is the largest contributor to global warming through road transportation.The health impact of transport emissions is also of concern. There is a recent survey of the studies on the effect of traffic emissions on pregnancy outcomes and it can highly affected the child in the womb and also it can cause cancer to the people like us.
