Modern transit systems are very complex and have high level of automation. The introduction of fully automated metro system has greatly reduced the dependency on human to drive the train and offered greater flexibility in the system operation. Prior to the implementation of each new automated metro system, extensive study has to be undertaken to ensure that the safety and reliability of the automated system will not be compromised. The paper describes Land Transport Authority (LTA)'s systems engineering process on safety and reliability for the design and construction of automated metro system projects in Singapore. The approach adopted has been proven to be successful through its implementation on several recent projects in achieving a high level of safety and reliability of automated metro systems.
