According to the National Highway Traffic Safety Administration's (NHTSA) 2001 data, while total traffic deaths in the United States increased by four tenths of a percent (+0.4%) from previous year, motorcycle deaths were up by 10 percent. Motorcyclist fatalities increased for the fourth year in a row since reaching a historic low of 2,116 fatalities in 1997. In 2001, 3,181 motorcyclists were k...

We address the problem of sub-ordinate class recognition, like the distinction between different types of motorcycles. Our approach is motivated by observations from cognitive psychology, which identify parts as the defining component of basic level categories (like motorcycles), while sub-ordinate categories are more often defined by part properties (like ’jagged wheels’). Accordingly, we sugg...

Steering a motorcycle or bicycle is counterintuitive; to turn right, you must steer left initially, and vice versa. You can execute this initially counter-directed turn by turning the handlebars explicitly ~called counter-steering! or by throwing your hips to the side. Contrary to common belief, gyroscopic forces play only a limited role in balancing and steering @D. E. H. Jones, Phys. Today 23...

Background: Road traffic accidents are considered to be a leading cause of injuries across the world. Human factors have been reported to play a key role in road traffic accidents. The present study aimed to explore the approaches to the reduction of human errors and motorcycle accidents. Methods: A participatory multistage intervention was designed and implemented through team participation. ...

Across all of Asia, urban road traffic is dominated by motorcycles. We analyze how form influences preferences for motorcycles usage, using a multinomial logistic regression model and data fr...

This paper introduces the idea of using mechanical steering compensators to improve the dynamic behavior of high-performance motorcycles. These compensators are seen as possible replacements for a conventional steering damper and comprise networks of springs, dampers, and a less familiar component called the inerter. The inerter was recently introduced to allow the synthesis of arbitrary passiv...
