The air transport

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

The reckless use of fossil fuels causes a lot of problems such as depletion of fossil fuels, rising oil prices, air pollution, and fine dust. 27% of the world's major energy sources are used for transportation, and most of the transportation fuels are used as fossil fuels.

Air travel is continuing to experience the fastest growth among all modes of transport. Increasing total fuel consumption and the potential impacts of aircraft engine emissions on the global atmosphere have motivated the industry, scientific community, and international governments to seek various emissions reduction options. Despite the efforts to understand and mitigate the impacts of aviation emissions, it still remains uncertain whether proposed emissions reduction options are technologically and financially feasible....

The budget deficit equivalent to total government spending tax minus total government spending revenue.If income tax independently, but depend on the net income, The relevance of seaports in the efficient working of an economy cannot be understated since all goods and passengers transported by sea require the use of, at least, two ports. In the majority of countries, most international trade (export/import), and in some cases also large shares of domestic trade, is done through maritime transport.

To appropriately mitigate environmental impacts from transportation, it is necessary for decision makers to consider the life-cycle energy use and emissions. Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure provision, and fuel production required for support. We present results of a comprehensive life-cycle energy, greenhouse gas emissions, and selected criteria air pollutant emissions inventory for automobiles, buses, trains, and airplanes in the US, including vehicles...
