Accident Data Coding
Saferparks adds additional coding to accident records
Some attributes, such as device type and accident category, are added to allow for logical categorization. Other attributes, such as tradename/generic and venue type, are added to mask specific ride identities in the data obtained from regulatory agencies. The intent was to extract the maximum amount of information about potential hazard patterns while reducing the potential for negative backlash against those parks and carnivals that provide the bulk of the data due to stricter local reporting laws.
Note: Coding is sometimes subjective and some degree of error is likely. Limitations and inconsistencies in the input data complicate this task. Not all records provide sufficient information to determine values for all Saferparks attributes.
Describing the Amusement Equipment
- Device Type identifies the type of ride or device involved in the report. Category descriptions and photographs were drawn from online sources such as Roller Coaster Database, The Flat Joint, Wikipedia and YouTube. Each Device Type includes two additional attributes used for grouping:
- Industry Sector is used to group devices according to the general category within the amusement business (e.g., 'amusement ride', 'water park', 'recreation')
- Device Category is used to group devices in Industry Sectors that cover a wide range. For example, amusement rides use this to group devices into coasters, spinning rides, etc.
- Tradename or Generic identifies the particular make/model, where known, or indicates the generic type of ride or device (e.g., kiddie plane, giant gondola wheel).
Describing the Owner/Operator
- Venue Type indicates the type of business (e.g., amusement park, family entertainment center, portable operator, zoo/museum).
Describing the Incident
- Accident Category is drawn from the narrative portion of the report, where enough detail is provided to indicate what happened to cause the injury or accident. Some of the categories are quite broad (e.g., body pain from normal motion). Others are quite narrow (e.g., electrical shock). In many cases, the accident narrative could fit into multiple categories, yet one is chosen. Each Accident Category includes an additional attribute:
- Part of Cycle helps to separate accidents that happen during the active part of the ride cycle from those that happen during load/unload or illnesses that may have delayed onset.
