Abstract (in Japanese) (See Japanese page) 
(in English) According to the commercialization of of automatic driving systems in recent years, the establishment of international standards of its safety assessment is a hot topic. Traditionally a typical human driver model with a certain level of abilities on recognition, judgment and operation was assumed in the safety assessment of the automobile, while a comprehensive analysis on all possible events should be considered if all information processing will be automated. In the present paper, we proposed a systematic protocol to extract scenarios with a certain risk as a functional level, which can be extended to logical scenarios easily, and demonstrated the extraction of 63 functional scenarios from all possible 336 cases in the case of interactions with two vehicles and two straight lanes, which is required to transfer for the re-examination in the logical level to estimate necessary ranges and types of model parameters in the level. The result resolved concerns of actual implementation methods, and highlighted an importance of the model-based analysis with critical parameter determinations in the logical level analysis.
