OBJECTIVE To estimate the contributions of five risk factors to changes in US traffic crash mortality: (1) alcohol use by drivers and pedestrians, (2) not wearing a seat belt, (3) lack of an air bag, (4) not wearing a motorcycle helmet, and (5) not wearing a bicycle helmet. DESIGN Longitudinal study of deaths; attributable deaths were estimated using data from other studies. SETTING US traf...

The paper illustrates the research outcomes of the integration of sensor system and control logic into a multibody simulation environment for motorcycle accidental dynamics analysis. One of the main objectives is to propose feasible scenarios for intelligent collision avoidance scheme for powered two wheeler (PTW) systems. A multibody model of a motorcycle that comprises a simplified model of t...

Research Note training have found mixed evidence for the effect of rider training on motorcycle crashes. Billheimer's (1998) matched-pair analysis of trained and untrained motorcycle riders is the only study conducted in the United States that has found a reduction in crashes among trained riders during the first 6 months following training. Among novice riders who rode less than 500 miles on a...

Motorcycle riders and passengers are much more likely to be killed or severely injured in a crash, on average about 15% of all traffic fatalities include motorcyclists. Between 2008 2019, the motorcycle crash frequency Wyoming was 286 crashes/year, 17 those being fatal. This paper assesses injury severity motorcycle-related crashes using 12 years data applying multinomial logistic regression mo...

This paper examines differences in accident characteristics and causation at different blood alcohol levels among 372 accident involved motorcycle riders who were tested shortly after they crashed. The subjects were part of a large, prospective, in-depth study of 1082 accident-involved motorcyclists in Thailand in which investigators went to the scene immediately after a crash to collect and an...

BACKGROUND The economic impact of helmet use remains controversial. Previous studies of injured motorcyclists suggest a marginal inpatient hospital cost difference between helmeted and unhelmeted riders. The purpose of this study was to expand the economic analysis of motorcycle helmet utilization to the point of injury by including motorcycle crash patients who do not require hospital admissio...

The purpose of this paper is to evaluate different formulas which are used to estimate the motorcycle’s pre-collision speed in motorcycle-to-car accidents. These formulas are based on measurable physical parameters such as motorcycle’ wheelbase change and fundamental physical laws such as conservation of momentum. The evaluation used data from crash experiments performed by the authors as well ...

This paper describes the development of the motorcycle (MC) model and validation using a MC – wall Full Scale Test (FST). Individual components like the seat, tires and shock absorbers were tested as per procedures given in ISO13232 [5] and their FE models were validated against the component test data. A crash test of the motorcycle with a rigid wall had been conducted. There is a reasonable m...

The increased popularity of mopeds and motor scooters in Australia and elsewhere in the last decade has contributed substantially to the greater use of powered two-wheelers (PTWs) as a whole. As the exposure of mopeds and scooters has increased, so too has the number of reported crashes involving those PTW types, but there is currently little research comparing the safety of mopeds and, particu...
