The article set a model and the solution on the various transportation means passenger transport of atmospheric pollution emissions of changsha-zhuzhou-xiangtan urban agglomeration. The results showed that the plant tam urban agglomeration development cycle economy should pay attention to the development of rail transit, appropriately control road traffic development. At the same time draw changsha-zhuzhou-xiangtan. Although it is rich in water resource but waterway traffic development is slow. Therefore, in the next few years, changsha-zhuzhou-xiangtan urban agglomeration of traffic transportation construction by public transportation development should give priority to, as urban rail transit network traffic skeleton polycentric urban layout and traffic structure mode.
