Beijing Jiaotong University (BJTU, formerly known as Northern Jiaotong University) is a national key university under the direct administration of the Ministry of Education and now is jointly supported by the Ministry of Education, the China Railway Corporation (formerly known as the Ministry of Railways) and Beijing Municipal Government.

BJTU is one of the first universities selected into the “National 211 Project” and the “985 Strength Discipline Innovation Platform” project, one of the first institutions authorized to confer master’s and doctoral degrees. BJTU, as the leading organization, has established the Collaborative Innovation Centre for Rail Transit Safety, which is one of the first 14 collaborative centers approved by the Chinese government to enter the “National 2011 Projects”.

The State Key Laboratory of Rail Traffic Control and Safety currently is the only one in the field of rail traffic in China. It was formally approved the construction in May, 2006 by the Ministry of Science and Technology of China, and successfully got through the acceptance in June 2010.

The establishment of the laboratory is closely connected with national long-term development and society needs of the state rail traffic, adhering to the research concept of “integrating the background on the application of fundamental theory research, and combining with the actual great demands of the formation of key technologies”. It conducts work according to the guiding ideology of “striving to make innovative research, breakthrough technologies and promote the industrialization of results”.

The work in the laboratory should focus on the areas of rail transportation organization, operation control, safety, information transmission, committed to creative applied basic theory and fundamental research work on the rail traffic control and safety science and technology, so as to form a rail traffic control and safety system of the core technology and equipment conforming to China’s national conditions with independent intellectual property.

The aim of the laboratory is to build the world-class research base for applied basic theory and fundamental research in the field of rail traffic, promoting the level for original innovation, integrated innovation, the introduction, absorption, further innovation as well as the training of the high-quality talents in China’s rail traffic control and safety. The research areas of the laboratory are divided into four fields:

  • rail traffic flow analysis and control theory
  • rail transportation safety and transportation organization theory and key technologies
  • rail transport operation control system analysis and integration mobile communications theory and key technologies for rail traffic
