Transportation is an engineering field that studies the layout of railway, highway, waterway and air transportation infrastructure and construction of vehicle application engineering, traffic information engineering and control, and transportation operation and management. Its engineering master's degree authorized unit to train engaged in railway, highway, port, ocean, waterway, airport engineering survey, design, construction and maintenance, locomotive, automobile, ship and aircraft application engineering, railway, highway, waterway, aviation information engineering and control , senior engineering and technical personnel in railway, highway, waterway and air transportation planning, operation and management. Transportation is a general term for transportation and post and telecommunications.
Transportation is the transportation of people and things by means of vehicles, resulting in a purposeful spatial displacement. Posts and telecommunications are the general term for postal services and telecommunications. Transportation is the basic need and prerequisite for economic development, the survival foundation and civilization symbol of modern society, the social and economic infrastructure and important link, the pioneer of modern industry and the leading sector of the national economy, and an important tool for resource allocation and macro-control. The important factors in the formation of territorial development, urban and economic layout play an important role in promoting social division of labor, the development of large-scale industries and the formation of economies of scale, consolidating the country's political unity, strengthening national defense construction, and expanding international economic and trade cooperation and personnel exchanges. In conclusion, transportation has important economic, social, political and national defense significance.
