POTENTIAL FOR TRANSPORT EFFICIENCY IMPROVEMENTS OF AVIATION TRANSPORTATION SYSTEMS

Kurzfassung

The growing traffic volume and simultaneous decline of the energy resources raise the question about the most efficient system for a dedicated transportation task. In this study an approach is presented to analyze and assess the transportation efficiency using examples of motor vehicles, railway systems and aeroplanes. For this purpose the transportation systems in Germany are used as representative examples to describe the methodology. Moreover the transportation flows and railway networks are analyzed for the different transportation systems on the bases of a 5-phases model to examine the influence of time. A comparison of the different technical characteristics of the various systems is given to highlight the potential and limitations for future developments. A graphical criterion developed in this study allows the assessment of the transportation efficiency of various systems considering the energy investment and time need in dedicated transportation missions.
