Current information on bicycle-safety education is provided for persons engaged in the development, evaluation, or use of bicycle-safety education programs and materials. Following an introduction to bicycle safety, section II provides a brief description of what is known about the size and composition of the U.S. population of bicycles and bicycle users. Section III describes what is known and not known about the magnitude of the bicycle-accident problem. Separate subsections are devoted to the discussion of bicycle/motor vehicle accidents. Data are presented on the characteristics of the accident-involved operators, the type and condition of the accident vehicles, the type of trip the operators were on when the accident occurred, and the types of accident locations. In addition, the accident-generation process is described for 36 different types of bicycle/motor-vehicle accidents. The accident location and the pre-crash actions of both vehicles are illustrated and discussed for the 25 most frequently occurring types of accidents and educational countermeasures are identified for each type of accident. Section VI contains a discussion and recommendations for specific educational objectives. The report concludes with a summary of the problems and issues that must be resolved before an effective educational program can be developed and implemented. (JH)
