Crash Analysis - crash severity categories

[dsinha]

Hello,

I am trying to run the FHWA analysis with the Crash Analysis solution. I noticed that the crash severity categories in the sample input data are the following:

• Not injured
• Non-incapacitating Injury
• Incapacitating Injury
• Fatal

However, the data I am working with has the following severity categories:

• Fatal
• Suspected Serious Injury
• Suspected Minor Injury
• Possible Injury
• Injury – Unknown Severity
• Unknown if Injured

I was wondering if anyone from the Solutions team has any ideas of how to reclassify these categories to match the four above. Or if anyone faced a similar issue in their own work and have some suggestions.

Thanks for your help!

Received this response from the Crash Analysis solution product engineer through Esri contacts:

The categories used when the solution was originally developed were based on the 2017 standard. It looks like your customer is using the newer 2024 standard, which is perfectly fine.
