In prehistoric ages, mankind needed transportation but not transportation systems. In recent times, accompanying the development of human activities, the importance of transportation and transportation systems has increased more and more. By the word “transportation”, the author means the spatial transfer of human beings, materials and articles and by the word “transportation system”, he means a system of structures, facilities, and equipment effectively transferring human beings, materials and articles. So, highway systems, railway systems, air transportation systems, marine and river transportation systems, water supply and sewage systems and fuel and oil transportation systems are included as transportation systems.
