Transportation includes the movement of people and goods from one place to another. The field can be loosely divided into infrastructure, vehicles, and operations, regardless of the mode of transportation.
Infrastructure consists of the fixed installations necessary for transport, and may be roads, railways, airways, waterways, canals and pipelines or terminals such as airports, railway stations, bus stations and seaports.
Vehicles traveling on the network may include automobiles, bicycles, buses, trains, people and aircraft.
Operations deal with the way the vehicles are operated, and the procedures set for this purpose including the financing, legalities and policies.
Recent attention toward energy prices in the US has caused municipalities, state governments, and individuals to re-look at their respective choices of transportation provided and/or taken. Long-term strategies are required to make significant changes in infrastructure, which impacts choices for vehicles and subsequent operations.
As alternative forms of energy continue to mature, and if consumer requirements continue demanding “greener” options, the business opportunities availing themselves to traditional transportation organizations will require some readjustment.
