How is a transportation method accurately described?

A transportation method is accurately described as a form of transport used for freight deliveries. This reflects the basic concept of what a transportation method encompasses within the context of logistics and supply chain management. It identifies the vehicle or modality—such as truck, rail, air, or sea—that is employed to move goods from one location to another.

While other options touch on related aspects of transportation, they do not provide a comprehensive definition of what a transportation method is. Defining services offered by the carrier pertains to the specific functionalities or features that a logistics provider may extend, rather than the transportation method itself. Shipping duration is more of an outcome of various factors, including the distance and type of method used, rather than a descriptor of the method. Lastly, classification of cargo types relates to the nature of the goods being transported rather than the method utilized to transport them. Therefore, identifying a transportation method primarily focuses on the actual physical means or vehicle used for freight movement.
