The Transportation Safety Board of Canada (TSB/C) is the short name, or applied title, for the federal agency mandated to carry out independent safety investigations of accidents and incidents of the marine, pipeline, rail and air modes of transportation. Our official name is the “Canadian Transportation Accident Investigation and Safety Board” reflecting the legislation under which we operate. The CTAISB Act was passed by Parliament in June 1989 and promulgated in March 1990.

Transportation Accident

The National Transportation Safety Board is furthering its accident investigation capabilities by implementing biomechanical tools and principles in its accident investigative process. Vehicle dynamics simulation is a commonly used investigative tool implemented to develop a complete understanding of how the vehicle moved and accelerated during an accident. Now the Safety Board is looking at both the reactions and actions of the occupants within the vehicle in response to the vehicle dynamics. This paper highlights two cases in which the principles and tools of biomechanics are applied to aid in the investigative process.

Transportation Accident

Accident investigation reports and related documents provide a wealth of information for rail professionals, even across different modes of transportation. This information can be used to improve operations, maintenance, safety, training, and emergency response. It can also guide the procurement and design of new equipment and infrastructure. At the same time, the historical nature of the information as well as the volume available and variety of sources can be a barrier to effective use. This paper will provide an introduction to some of the sources of transportation accident data and reports, including the variety of topic-specific information and special reports that are available. The discussion will include less-considered sources of accident information including foreign transportation safety boards as well as specialized federal and state agencies. Accidents that were investigated and reported on by more than one organization are also discussed.

Abstract. Situational awareness is a concept increasingly used in aircraft accident investigation reports. We analyzed 94 general aviation accidents in which situational awareness was mentioned by the National Transportation Safety Board investigator to determine factors that are significantly more often associated with fatality. We found a consistent use of the situational awareness concept, mainly applied to situations in which aircraft inadvertently collided with each other, with other man-made objects, and with various kinds of terrain. A significantly higher proportion of fatal accidents occurred during nighttime, in instrument meteorological conditions, or low visibility conditions. In addition, flights occurring during the cruise phase or in combination with spatial or geographical disorientation proved most often fatal.

The National Transportation Safety Board in the United States and the Transportation Safety Board of Canada publish reports about major railroad accidents. The text from these accident reports were analyzed using the text mining techniques of probabilistic topic modeling and k-means clustering to identify the recurring themes in major railroad accidents. The output from these analyses indicates that the railroad accidents can be successfully grouped into different topics. The output also suggests that recurring accident types are track defects, wheel defects, grade crossing accidents, and switching accidents. A major difference between the Canadian and U.S. reports is the finding that accidents related to bridges are found to be more prominent in the Canadian reports.
