Factor complexity is regarded as a typical characteristic of traffic accidents. This paper proposes a novel method, named boosted regression trees (BRTs), which is particularly appropriate for investigating complicated and nonlinear relationships in high-variance traffic accident data. The Taiwan 2004–2005 single-motorcycle accident data are adopted to demonstrate the usefulness of BRTs. Tradit...
