MIVIA road audio events data set

The dataset

The MIVIA road audio events data set is composed of a total of 400 events for road surveillance applications, namely tire skidding and car crashes. The events are divided into 4 folds of 100 events each, in order to account for cross-validation experiments.


The sounds have been registered with an Axis P8221Audio Module and an Axis T83 omnidirectional microphone for audio surveillance applications , sampled at 32000 Hz and quantized at 16 bits per PCM sample. The audio clips are distributed as WAV files.
Each fold contains a number of audio file of about 1 minute duration, in which a series of hazardous events is superimposed to a typical road background sound. Each audio file has a different background sound, so that several different real situations are simulated.
The events of interest are organized in two classes (car crashes and tire skidding) and their total duration in the data set is reported in the following table

  Training set
  #Events Duration (s)
Background 2732
Car Crashes 200 326,38
Tire skidding 200 522,5
