Advances in transportation

Technological advances in transportation have included the development of super speed trains,

such as Japan’s ‘bullet train’ of the 1960s and Frances TGV (Train de Grand Vitesse) of the 1970s and 1980s. These advances gave engineers the inspiration to design such experimental railroad systems as the magnetic levitation1, or maglev train, which by the early 1990s had only short test systems set up in Germany and Japan. Improvements in power generation and transmission and concern for the air and noise pollution caused by diesel engines have prompted automobile makers to develop cars that will run on alternative types of fuel. One result has been the prototype of an electric car. A greater variety of ships, including submarine tankers and fast surface ships, have been developed. Other new types of vessels that are available include the hydrofoil2, which travels on sea wings with its hull3 above water, and the hovercraft4, which rides above the water on a cushion of air. The widespread use of atomic power for ship propulsion is a major research goal. STOL (short takeoff and landing), VTOL (vertical takeoff and landing), and supersonic aircraft have been adopted. These new technologies have made vehicles quieter. Passenger travel has improved in speed and comfort. Freight transport costs less because larger vehicles are used and operating efficiency has increased. The computer is used for record keeping, traffic control, navigation, and other routine operations.

In the more distant future, rocket transportation may become feasible, perhaps in combination

with orbiting satellites, enabling all points on Earth to be connected in less than an hours travel time.

Underground gravity vacuum tubes may permit freight and passengers to travel between stations

thousands of miles apart also in less than an hour. Improvements may be expected in transportation management techniques. Some forms of transportation now under private ownership, management, and operation will increasingly depend on public financing or control, just as urban mass transit now does. Some forms of transportation will be integrated into multimodal organizations, both public and private, in order to move people and goods with a minimum of cost, inconvenience, and delay.

Innovative communications systems, however, have already made much travel unnecessary.

Teleconferencing enables people to hold meetings and see each other without having to travel.

Computer networking makes cooperative work possible, without the workers leaving home or

office.
