I'm trying to find an open-source dataset for car crash detection using sensor data including accelerometer. Is there any open-source dataset available? Basically I want to detect car crashes only using non-car information, such as accelerometer data from a smartphone mounted on a car.

I was told about FARS, but wasn't really sure if this is what I want. I couldn't find a accelerometer dataset there.

Instead of the NHTSA FAR data, you may want to look at the NHTSA Vehicle Crash Test Database. This does contain accelerometer data.

That said, I doubt they are using a phone's accelerometer to create this dataset.
