What is drived demand in transport?

Derived demand in transport refers to the concept that the demand for transportation services is driven by the need for goods and services to be moved rather than a desire for transportation itself. For example, if a company needs to ship products to customers, the demand for trucks or shipping services arises from the need to deliver those products, not from a direct desire for the transport vehicles. This relationship highlights how transport demand is closely linked to economic activities and consumer needs.
