A connected and automated vehicle accident reduction amount calculation method, comprising: obtaining sample documents by means of screening; extracting effective information of the sample documents, and obtaining a safety benefit of each technology of each sample document; performing heterogeneity inspection on the safety benefit of each technology of each sample document, and excluding an inappropriate sample document; merging the safety benefit of each technology of each sample document using a random effect model to obtain a merged safety benefit of each technology of the sample documents; performing, on the basis of the merged safety benefit, bias inspection on the safety benefit of each technology of each sample document using a funnel plot to obtain a final merged safety benefit of each technology of the sample documents; and on the basis of the final merged benefit safety, obtaining an accident reduction amount when connected and automated vehicles are used. According to the method, selected technologies can be applied to connected and automated vehicles to reduce an accident amount.
