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...

BACKGROUND Few studies have examined potential disparities in access to transportation infrastructures, an important determinant of population health. PURPOSE To examine individual- and area-level disparities in access to the road network, public transportation system, and a public bicycle share program in Montreal, Canada. METHODS Examining associations between sociodemographic variables a...

One fundamental aspect of promoting utilitarian bicycle use involves making modifications to the built environment to improve the safety, efficiency and enjoyability of cycling. Revealed preference data on bicycle route choice can assist greatly in understanding the actual behaviour of a highly heterogeneous group of users, which in turn assists the prioritisation of infrastructure or other bui...

Cycling is popular for transportation and leisure. Bike helmets are used to mitigate the risk of head injury in collisions or falls. According to NHTSA, 52,000 cyclists were injured in the US in 2010. Head injuries accounted for two thirds of hospital admissions, among cyclists. Despite strong epidemiological evidence of efficacy, some researchers and many lay people argue that bicycle helmets ...
