Independent Safety Assessment Strategy for Urban Rail Transit Vehicles
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 3
Abstract
[Objective] China′s independent safety assessment (ISA) on urban rail transit vehicles is still in its initial development stage in that the relatively complete theories and standardization remain to be formed, and there are still deficiencies in specialization, systematization and other aspects. Therefore, it is necessary to study the strategy of ISA on urban rail transit vehicles. [Method] In view of the FAO (fully automatic operating system) urban rail transit projects opened for operation and under construction in China, and with focus on hidden hazard identifying and risk control in vehicle system, ISA is conducted on the safety assessment activities and the key points of the safety certification system at stages of vehicle design, vehicle manufacturing, and test verification. Focusing on the special risks of vehicles in the FAO projects, ISA mainly includes safety document evaluation, safety assessment on special risk, and safety audit, and runs through the entire vehicle construction period. [Result & Conclusion] Some of the FAO urban rail transit projects in China that complete the vehicle ISA show that the risk control related to the vehicle system is acceptable. Theoretical and practical experience in evaluation strategies, methods, and reports is accumulated. However, deficiencies still exist in specialization and systematization. It is necessary to improve the vehicle ISA system and form corresponding ISA standards for China.
