Abstract Human Factor and Human Error are main reasons that lead to road accidents in Hong Kong. Apart from medicated or drunk cases, human factors are still affecting the road safety in most situations, including driver negligence, environmental influence, etc. As a result, the study of elimination of human error in safety issue became the main study in modern transportation research field. In light of the fact that Human Factor models such as the SHELL and Dirty Dozen have been used successfully in the aviation industry, in this paper both of them were applied to analyze a bus accident occurred in February 2018. To clarify the human factor affection and its role in the accident, the technical specification difference between single deck and double-decker buses, as well as other factors like weathers and time are neglected so the analysis is solely based on the human factor effect, and the conclusion and recommendation are generated from the investigation result.
