Abstract: Transportation System Engineering is one of the most important area in the System Engineering. It played key roles both in the theoretical thinking and the practice application.
Many ideas and methods in the System Science and System Engineering have found best examples and explanation in the Transportation System Engineering.
During these years,in the System Science many newest ideas and methods emerged,which have provide more powerful tool for us to observe, research and control complex systems, for
example, so-called Complex Adaptive System Theory (CAS Theory). As one of the most
important application areas, Transportation System Engineering can find many useful
suggestion in these new progress.

Key words: Complex adaptive system, Transportation, Control complex systems
