Question

The movement of goods and services from the supply location to demand location neceitate the need for transport

Answer 1

Each transport more shares the common goal of fulfilling a derived transport demand, and each transport mode thus fills the purpose of supporting mobility. Transportation is a service that must be utilized immediately since unlike the resources it often carries, the transport service itself cannot be stored. Mobility must occur over transport infrastructures having a fixed capacity, providing a transport supply. In several instances, transport demand is answered in the simplest means possible, notably by walking over a landscape that has received little or no modifications. However, in some cases elaborate and expensive infrastructures and modes are required to provide mobility, such as for air transportation.
