Intelligent Transportation system (ITS) is one of the leading edges of the modern transportation technology. It has been developed for more than 20 years since the name was officially adopted in 1994. The development of the advanced technology and the travelers' new demands have brought about different and distinctive technical directions and R & D hot spots in the ITS field. Firstly, this paper analyzes the hot spots and the dynamics of the international ITS research and development in recent years, focusing on the progress of the ITS technology and the hot areas brought by the new generation of the information technology, as well as the direction of the ITS technology and the industry development. Secondly, compared with the development of the ITS in China in recent years, the paper analyzes the similarities and differences of the development ideas at home and abroad and the enlightenment gained from the hot research and development of developed countries. Finally, some suggestions on the development of the ITS are put forward, including seeking truth from facts to treat the gap, the similarities and the differences at home and abroad, strengthening the research and development of the ITS characteristic technology, and establishing a new development model based on the market.
