OBJECTIVE This study sought to evaluate associations between sleep time and bicycle accidents, falls under various circumstances, and dental injuries in adolescents. METHODS A total of 61,696 participants ranging from 12 to 18 years of age who completed the Korea Youth Risk Behavior Web-based Survey (KYRBWS) in 2013 were enrolled in this study. Bicycle riding accidents were analyzed for 17,23...

Cycling is popular among children, but results in thousands of injuries annually. In recent years, many states and localities have enacted bicycle helmet laws. We examine direct and indirect effects of these laws on injuries. Using hospital-level panel data and triple difference models, we find helmet laws are associated with reductions in bicycle-related head injuries among children. However, ...

This paper describes the development and testing of a three-dimensional computer model of a bicycle and rider. The model was developed using MADYMO and will assist in the reconstruction of bicycle crashes. In particular the model will be used to determine the rider’s pre-impact speed and kinematics during the impact. Three exemplar real-world bicycle crashes were reconstructed using a multi-bod...

Although bicycles in Japan are widely used for going to school, shopping and so on, satisfaction levels of cyclists for the condition of streets are not high. This is because most bicycle space is shared with pedestrians. The aim of this study is to find evaluation factors from a viewpoint of bicycles’ perception by monitoring cycling behavior using a Probe Bicycle System. The Probe Bicycle dev...

The sixth edition of Hazard from the Victorian Injury Surveillance System departs a little from the usual Hazard format. The first section is devoted to a preliminary evaluation of the effects of the Victorian bicycle helmet legislation. This edition also undertakes an examination of all bicycle related injuries in the usual format. Bicycle related injuries occur in residential and recreational...

Currently, mainly aggregated statistics are used for bicycle crash risk calculations. Thus, the understanding of spatial patterns at local scale levels remains vague. Using an agent-based flow model and a bicycle crash database covering 10 continuous years of observation allows us to calculate and map the crash risk on various spatial scales for the city of Salzburg (Austria). In doing so, we d...

This paper presents key technologies and system integration issues of the KAIST interactive bicycle simulator. The rider on the bicycle feels the motion and has the visual experience as if he/she is riding in the campus of the Korea Advanced Institute of Science and Technology. The simulator consists of a bicycle, a Stewart platform, a Magneto-Rheological handle and a pedal resistance system to...

Geographical information systems (GIS) offer an integrated platform for relating, modeling and analyzing multiple perspectives on the road space. They can thus be employed in all stages of better understanding bicycle safety from an explicitly spatial perspective and provide the basis for informed decisions in the context of cycling promotion. In the following it is briefly sketched why safety ...
