BACKGROUND Public bicycle-sharing initiatives can act as health enhancement strategies among urban populations. The aim of the study was to determine which attitudes and perceptions of behavioural control toward cycling and a bicycle-sharing system distinguish commuters with a different adherence to bicycle commuting. METHODS The recruitment process was conducted in 40 random points in Barcel...

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...

The factors associated with severity of the bicycle crashes may differ across different bicycle crash patterns. Therefore, it is important to identify distinct bicycle crash patterns with homogeneous attributes. The current study aimed at identifying subgroups of bicycle crashes in Italy and analyzing separately the different bicycle crash types. The present study focused on bicycle crashes tha...

This research uses an ordered-response model to evaluate the factors that impact bicycle frequency use for an individual’s commute to and from work. The data used for this paper were gathered during an original survey effort conducted over the Internet in 2002. The paper presents empirical results and discusses the policy implications of these results for urban planning. In addition, the paper ...

BACKGROUND Bicycle injuries are a leading cause of accidental death among children in the world, and bicycle-related injuries are also very common in China, thus to find out bicycle injury risk factors is imperative. This study aims to identify the cyclist-, bicycle- and road-related risk factors of bicycle injury, to develop health education programs as an intervention and to provide a scienti...

An interactive bicycle simulator with six degrees of freedom motion system could bring the rider a very realistic riding feeling. An important component of the simulator is the full bicycle dynamic model that simulated the two-wheeled bicycle dynamics. It consists of two slightly coupled submodels: The stability submodel and the vibration submodel. The stability submodel solves the stability of...

Traditional accident risk prediction models need adequate data on explanatory variables, most importantly data on traffic flows. However, in the case of accidents between bicycles the availability of such data is often limited. Therefore, alternative bottom-up simulation modelling approaches are expected to complement traditional equation-based models. In this paper we present an agent-based ap...

Most research on cyclist safety is focused on bicycle motor vehicle crashes. Only a few studies address single-bicycle crashes (i.e. a fall or obstacle collision), in spite of the fact that most cyclists admitted to hospitals are single-bicycle crash victims. This study developed a categorization of single-bicycle crash types. A draft categorization was developed based on the scarce literature ...

Bicycle (n, k)-gons are equilateral n-gons whose k-diagonals are equal. In this paper, the order of infinitesimal flexibility of the regular n-gon within the family of bicycle (n, k)-gons is studied. An equation characterizing first order flexible regular bicycle (n, k)-gons were computed by S. Tabachnikov in [7]. This equation was solved by R. Connelly and the author in [3]. S. Tabachnikov has...
