Abstract
Traffic safety is one of the crucial problems in many countries. Understanding the conditions under which people are more likely to be killed or more severely injured in traffic accidents, can improve the overall driving safety level. Factors that affect the risk of increased injury of occupants in an automotive accident include characteristics of the person, environmental factors, and roadway conditions at the time of the accident, technical characteristics of the vehicle itself, among others. In this study, we used a large crash data set along with several machine learning methods to model the complex relationships between the number of crashes that correspond to different injury severity levels and the crash related risk factors. Sensitivity analysis is conducted on the trained predictive models to identify the prioritized importance of crash-related factors. The results expose the relative importance of crash related risk factors with the changing levels of injury severity.
