This study aimed to examine the practices and perceptions of motorcycle taxi drivers concerning the use of personal protective equipment (PPE), based on field research and an exploratory and descriptive qualitative approach. Thirty motorcycle taxi drivers from Jequié, Bahia State, Brazil, were interviewed. Data collection used a semi-structured interview and questionnaire. Data were analyzed us...

This paper presents a motorcycle direct dynamic formulation by the Jourdain’s principle approach. This vehicle is considered as an assembly of six rigid bodies and the resulting equation of motion allows to simulate 11 Degrees of Freedom (DoF). The vehicle geometry is described and a step by step procedure is introduced to evaluate the kinematics and the generalized efforts of the considered ve...

conclusions the result of this study did not find an independent association between adhd and helmet use. results univariable analysis showed the mean of the age variable was significantly higher in the helmeted group, 26.94 ± 7.72 vs. 23.08 ± 7.7.32, (p < 0.001). the majority of the non-helmeted group was single (p < 0.001). subjects with secondary educational level were more often in the helm...

The effect of antilock braking systems (ABS) on motorcyclist fatal crash risk in 2005-06 was studied by comparing fatal crash rates per registrations of motorcycles with and without ABS. Study motorcycles included those for which ABS was optional equipment and could be identified as present by the model name. Fatal motorcycle crashes per 10,000 registered vehicle years were 38 percent lower for...

Scooter and moped sales have increased at a faster rate than motorcycle sales over the last decade in countries such as Australia, Canada and the United States. This may be particularly evident in jurisdictions where moped riding is permitted for car license holders and a motorcycle license is not required, such as in Queensland, Australia. Having historically comprised only a small proportion ...

BACKGROUND Use of helmets plays a major role in preventing injuries or decreasing injury severity among motorcycle riders. Use of helmets may depend on personal factors such as psychological factors. OBJECTIVES The aim of this study was to independently assess the association between helmet use among motorcycle riders and ADHD scores, with controlling the accident history and was taken more s...

The statistical data published by National Police Agency, Taiwan, indicated that the motorcycle induced the highest accident rate, and drunk driving ranked first among the traffic fatality causes in 2007. The high traffic accident rate was attributed to the alcohol decaying driver reaction and the increase of frequency of using motorcycle in daily life as the car parking space and driving cost ...

Despite the proven effectiveness of helmets in avoiding or reducing the severity of brain injuries and the law requiring their compulsory use, both by drivers and passengers of motorcycles, approximately 20% of Spanish adolescent motorcycle users do not wear them. This study analysed the pattern of motorcycle and helmet-use in a sample of Spanish adolescents (age range 14–17; n = 874) and the r...

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 ...
