This research project focused on motor carrier fleet safety management, namely the problems fleet managers confront and the methods that are available to address these problems. The authors conducted a literature review, held discussions and did interviews with experts, and solicited suggestions from the TRB synthesis panel. Twenty discrete safety problems and 28 safety management methods were identified based on this research information and the knowledge and experience of the authors. Problems addressed encompassed driver safety, knowledge, skills, behaviors, alertness, physical/medical condition, and attitudes. In addition, several vehicle-related problem areas, such as vehicle maintenance and inspection, were considered.
