SCM is the process of planning, controlling and executing the flow of a product by way of the varied stages of its lifecycle, from raw supplies to manufacturing and distribution. While some TMSes focus on a single mode of transportation, most systems help multimodal and intermodal transportation. In multimodal, a single provider makes use of at least two modes of transportation — truck, rail, air or sea — and is legally answerable for assembly the terms of the contract, although it would rent subcarriers.

The services help air, highway, railroad, pipeline, water, and even house transportation. The design aspects of transportation engineering embrace the sizing of transportation amenities , figuring out the supplies and thickness used in pavement designing the geometry of the roadway . The planning elements of transportation engineering relate to parts of urban planning, and contain technical forecasting decisions and political components. Technical forecasting of passenger travel usually entails an city transportation planning mannequin, requiring the estimation of trip era , journey distribution , mode selection , and route task . refined forecasting can include different elements of traveler decisions, together with auto ownership, journey chaining and the choice of residential or business location . Passenger trips are the major focus of transportation engineering as a result of they typically characterize the peak of demand on any transportation system.
