Answer -
Transport is a service or facility for the carriage of persons and goods from one place to the other using humans, animals and different kinds of vehicles. Such movements take place over land, water and air. The significance of a mode depends on the type of goods and services to be transported, costs of transport and the mode available. International movement of goods is handled by ocean freighters. Road transport is cheaper and faster over short distances and for door- to-door services. Railways are most suited for large volumes of bulky materials over long distances within a country. High-value, light and perishable goods are best moved by airways.
None of the transport system is self-sufficient. For having a well-managed transportation system a proper link between all the modes is essential. Ports are a point of collection of goods carried by waterways; they must have efficient linkage with railways and roadways so that the goods can be taken to interiors. Railways are efficient in connecting far off places but they can’t penetrate deep into interiors or provide door to door service, for that an efficient road system along with transportation facilities like buses etc. should be available.
