OBJECTIVES The purpose of the study was to examine associations between bicycle helmet use and attitudes among U.S. college students. Bicycle helmet use was assessed for two different bicycle use purposes: commuting to school and recreation. MATERIALS AND METHODS Student bicycle riders were recruited on the campus of a large public university in Colorado. Questionnaire development was guided ...

in recent decades, urban planning has tended to humanist urbanism. in this regard foot travels and bicycle use are the two strategies that urban planners and transportation engineers are using them as adequate alternatives for making cities more people friendly. using bicycle is known as a strategy that has a great role in decreasing traffic among developing countries in recent decades. these c...

INTRODUCTION Cycling is a major activity for adolescents in Canada and potential differences exist in bicycling-related risk and experience of injury by population subgroup. The overall aim of this study was to inform health equity interventions by profiling stratified analytic methods and identifying potential inequities associated with bicycle-related injury and the use of bicycle helmets amo...

OBJECTIVES To describe the incidence, type, and severity of injuries related to the use of bicycle-towed trailers for transporting children and to compare them with injuries associated with the use of child seats mounted on adult bicycles. DESIGN A retrospective analysis of data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission for 1990 to 19...

It is well known that skilled bicycle riders can balance and propel themselves forward using motions of the handlebar. We present the complete nonlinear dynamics and control of such a pedal-less bicycle with a rider. Propulsion is achieved not by pedaling but by a cyclic motion of the steering axis of the bicycle. It is shown that this kind of actuation results in net forward motion of the bicy...

BACKGROUND Because of the increased number of bicycle riders and governmental promotions, a recent increase in the construction of bicycle lanes has occurred. We aimed to characterize injuries specific to bicycle lane accidents by comparing them with injuries that occurred on regular roadways. On the basis of our findings, we provide suggestions on proper preventive strategies. METHODS We per...

UNLABELLED Electrically assisted bicycles (EAB) are an emerging transportation modality favored for environmental reasons. Some physical effort is required to activate the supporting engine, making it a potential active commuting option. PURPOSE We hypothesized that using an EAB in a hilly city allows sedentary subjects to commute comfortably, while providing a sufficient effort for health-en...

We estimated the annual cost of bike and pedestrian trails in Lincoln, Neb, using construction and maintenance costs provided by the Department of Parks and Recreation of Nebraska. We obtained the number of users of 5 trails from a 1998 census report. The annual construction cost of each trail was calculated by using 3%, 5%, and 10% discount rates for a period of useful life of 10, 30, and 50 y...

INTRODUCTION The objective of this study was to survey Canadian parents on their attitudes and beliefs about bicycle helmet legislation and to compare responses from parents living in provinces with and without legislation. METHODS A national survey of 1002 parents of children aged under 18 years was conducted. Chi-square tests were used to compare responses from the surveyed parents in the d...

BACKGROUND Bicycling is healthy but needs to be safer for more to bike. Police crash templates are designed for reporting crashes between motor vehicles, but not between vehicles/bicycles. If written/drawn bicycle-crash-scene details exist, these are not entered into spreadsheets. OBJECTIVE To assess which bicycle-crash-scene data might be added to spreadsheets for analysis. METHODS Police ...
