Under the Hood
Accident Explorer was created as a simple demonstration of an online application that uses the machine learning capabilities of MIOsoft MIOvantage software.
In Accident Explorer, MIOvantage uses different aspects of the accident data, such as geographic proximity, to automatically cluster accident data points. This creates 4,353 potentially meaningful clusters from data on over 215,000 fatal vehicle accidents.
