Exploring the Factors that Impact Injury Severity using Hierarchical Linear Modeling (HLM)

Injury Severity describes the severity of the injury to the person involved in the crash. Understanding the factors that influence injury severity can be helpful in designing mechanisms to reduce accident fatalities. Several research studies have examined the relationship between injury severity and the possible factors that can be related to the severity of the injury. These include driver-related factors, vehicle characteristics, and road and weather conditions at the time of the accident. Various data mining techniques were used to identify the possible factors that can be associated with the occurrence of the crashes. Examples of the techniques include classification algorithms, network models, and exploratory models [4][5][6].
