|1) The National Safety Council
defines a disabling injury as one causing death, permanent disability, or any degree of
temporary total disability. Temporary total disability is defined as an injury which
renders the injured person unable to perform regular duties on one or more full calendar
days after the day of the injury.
2) Accidents involving child tricycles and "big wheels," are clearly underrepresented in this sample. Discussions with representatives of Dunlap and Associates (Blomberg, 1977) revealed that accidents involving tricycles and big wheels are usually reported as pedestrian accidents. For a large sample of pedestrian accidents that occurred in Los Angeles, it was found that tricycle and big wheel accidents together accounted for about two percent of all pedestrian accidents and five percent of all child pedestrian accidents.
3) The term "preview time" is used here to refer to the time available between the point at which the operator first observed the other vehicle and the point at which the collision occurred.
4) Unless stated otherwise, all the roadways referred to throughout this section are two-way roadways.
5) Throughout this section, the term "education" will be used in two different ways. When referring to general education and training programs or general education and training objectives, only the term "education" will be used; the term "training" will be dropped to avoid repeating "education and training" again and again. When referring to specific education and training activities, the term "education" will be used to refer to activities that impart knowledge; the term "training" will be used to refer to activities that enhance specific perceptual or motor skills.
6) Readers who have not had the opportunity to review a sample of bicycle-safety education programs and materials are encouraged to review the inventory of educational objectives presented in Appendix B. This inventory was compiled from a study of ten recent bicycle-safety education programs.
7) The term "trip" is used here in the broadest sense of the word. it includes both travel to a specific destination and recreational riding with no specific destination.
8) Invalid assumptions also had an adverse effect on bicyclists' assessment of the need to search for hazards and the need for evasive action once a potential threat had been observed. However, these are Reactive-Phase functions and will not be discussed until later.
9) These distractions are listed in the approximate order of their importance.
