Development and sustainable strategies of RITS in China.

In China, the railway has always been a key factor in the economic development. The intelligent railway is the trend of current railway development, since it plays an important role in the sustainable transportation system that minimizes environmental impacts and contributes greatly to social and economic prosperity. And in this paper, firstly the current transportation situation in China is given and then some basic concepts of the Railway Intelligent Transportation System (RITS) are talked about as well. Secondly, based on the railway building programs in China, the necessity of RITS is analyzed to show its strategic position. Then, according to the previous research work, the overall architecture of RITS is introduced here so as to make a clear picture of what is RITS and how it works. Finally, apart from key technologies in RITS, its sustainable strategies are mentioned to show the future development of RITS. © 2011 IEEE.
