Transport plays a key role in our lives, transforms our outlook and has a massive impact on social and economic development. In addition, emerging of the technologies are also associated with the social and economic development. Accordingly, Intelligent Transport System (ITS) has evolved with Chinese social and economic transformation. In the 1990s, China started a large-scale construction of road infrastructure, and ITS was considered as a futuristic and expensive tool box. It was crucial for Chinese government to identify when and how to integrate new technologies into transportation systems and to formulate an appropriate development strategy, especially with ITS. Through more than 20 years development, Chinese ITS has gained remarkable achievements. This paper will firstly review the policy, strategy and experience of ITS development and deployment in China, then its import as well as the international cooperation and cases will be illustrated, and finally conclusions and experience will be presented, in particular to other developing countries, on ITS development.
