Research on the Quality Foundation System of Urban Rail Transit Based on Credibility
With its advantages of speed,convenience,safety,large capacity,and high efficiency,urban rail transit has become the first solution to solve urban transportation problems in China.Urban rail transit is a national key development strategy emerging industry,and China leads the world in the aspects of construction speed and operation scale.Although the industry is developing rapidly,the contradiction between operation and maintenance costs and insufficient quality and safety control capabilities becomes increasingly prominent.There is a lack of systematic research,and it is difficult for the National Quality Infrastructure(NQI)technology to play a coordinated role and achieve its effectiveness.Conducting the research on the credibility of urban rail transit is the way to address the problems.It is necessary to establish a NQI collaborative technology system that requires full lifecycle credibility and propose a comprehensive application solution for NQI technology in the intelligent era.
