英文摘要：

Based on the survey of commercial vehicle grave or extraordinarily serious road traffic accident, the related objects and its management status of commercial vehicle transportation safety aer analyzed. The principles of feedback control and risk balance are introduced to analyze the feasibility of accident prevention, the involved objects related to feedback control and its mutual relationship. Four key problems and advices to commercial vehicle transportation accident feedback control including deep survey and analysis of traffic accident, commercial vehicle transportation system safety status monitoring and recording, illegal behavior risk level and technical measure integration promoting, feedback control technical supporting platform building are put forward.
