China Shows Leadership in Bike Share and Greenways

This article describes how cities in China are embracing bicycle sharing systems and the establishment of greenways in order to improve mobility and quality of life.  The first bicycle sharing system in China was opened four years ago. Since then cities have established a variety of high-tech systems that include automated docks operated with smart cards and bicycles with direct drive pedals. Chinese cities are also implementing greenways and promoting them as walking and bicycling networks as well as public space. More than 6,000 km of greenways have opened in the past two years, and another 14,000 km are in the planning stage.

Trends in Electric Bike–Related Injury in China, 2004-2010

This study describes electric bike–related injuries from 2004 to 2010, and suggests injury prevention strategies to reduce electric bike–related injuries in China and other countries.

Effects of Bicycle Helmet Laws on Children’s Injuries

This paper estimates the effect of bicycle helmet laws which have been enacted in many states and localities in the US on injuries requiring emergency department treatment. 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, laws also are associated with decreases in non-head cycling injuries, as well as increases in head injuries from other wheeled sports. Thus, the observed reduction in bicycle-related head injuries may be due to reductions in bicycle riding induced by the laws.

Evolution of bicycle helmet use and its determinants in France: 2000-2010

This paper examines helmet use in France between 2000 and 2010 with a particular focus on voluntary behaviour rather than legal compulsion.

The Structure of Spatial Networks and Communities in Bicycle Sharing Systems

This paper employs visualization, descriptive statistics and spatial and network analysis tools to explore the usage of bicycle sharing systems in five cities.  The paper uses various techniques to investigate features specific to the unique geographies of each, and uncovering similarities between different systems. Journey displacement analysis demonstrates similar journey distances across the cities sampled, and the (out)strength rank curve for the top 50 stands in each city displays a similar scaling law for each. Community detection in the derived network can identify local pockets of use, and spatial network corrections provide the opportunity for insight above and beyond proximity/popularity correlations predicted by simple spatial interaction models.

Evaluating Active Transport Benefits and Costs

This report describes methods for evaluating the benefits and costs of active transport. It describes various types of benefits and costs and methods for measuring them. These include direct benefits to users from improved active transport conditions, and various benefits to society from increased walking and cycling activity, reduced motor vehicle travel, and more compact and multi-modal community development. It discusses active transport demands and ways to increase walking and cycling activity. This analysis indicates that many active transport benefits tend to be overlooked or undervalued in conventional transport economic evaluation.

Acceptability of rider assistive systems for powered two-wheelers

This paper aims to understand general and specific factors that are likely to influence the acceptability of advanced rider assistance systems for powered two wheelers (electric bicycles or Pedelecs).

Bicyclists overestimate their own night-time conspicuity

This study found that bicyclists overestimated their conspicuity compared to previously collected recognition distances and underestimated the conspicuity benefits of retroreflective markings on their ankles and knees. Participants mistakenly judged that a fluorescent vest that did not include retroreflective material would enhance their night-time conspicuity.
