• Abstract:
  In December 2018, the International Organization for Standardization (ISO) released Edition 2 of the industry’s functional safety standard for road vehicles, ISO 26262. Although the previous edition of ISO 26262 focused on light-duty passenger vehicles, this new edition includes considerations for buses. This report presents the findings from an analysis that applies key concepts from Edition 2 of the ISO 26262 standard to a set of Level 0 to Level 2 driving automation systems in the context of a generic 40-ft transit bus. Although this study found that many of the same basic hazards exist for transit buses as for other vehicles, specific aspects of transit bus operations resulted in additional hazards and associated functional safety measures. The results of this research provide a useful reference for manufacturers on the application of hazard analysis and risk assessment concepts in the context of transit bus applications and for comparison of the results from internal system-specific hazard and safety analyses.
