Motorcycles have become a popular form of transportation in the United States. Since 1961, motorcycle registrations have increased at nearly four times the rate of all other vehicles . In 1977, motorcycle registrations in this country passed five million. In the same year about 500,000 motorcycles were involved in accidents, resulting in about 4,000 deaths and 400,000 injuries (1). Motorcycles ...

This poster presents a study to assess one's ability to detect motorcycles under different conditions of conspicuity while performing a secondary visual load task. Previous research in which participants were required to detect motorcycles revealed differences in age (young adults/older adult) as well as differences associated with motorcycle conspicuity conditions. Past research has specifical...

Issues related to motorcycle safety in China have not received enough research attention. As such, the causal relationship between injury outcomes of motorcycle crashes and potential risk factors remains unknown. This study intended to investigate the injury risk of motorcyclists involved in road traffic crashes in China. To account for the ordinal nature of response outcomes and unobserved het...

The addition of racing exhaust to a vehicle will greatly affect the quality emissions. Racing exhausts that use FreeFlow system which throws remaining combustion gases out immediately without any deflection and catalyst in exhaust. DB Killer uses nest-shaped copper material, besides reducing noise it also reduces excessive emissions material is easy obtain, inexpensive, has simple manufacturing...

We investigated motorcycle rider death rates between states with full motorcycle helmet laws and those without. This was done using both unadjusted bivariate analyses and multivariate random-effects generalized least squares regression models of rider death rates. Multivariate models were adjusted for the competing influences of several explanatory variables, including the existence of a motorc...

Motorcycle accidents constitute a major cause of death and disability among the young. This paper draws on routinely collected data to describe the trends for motorcycling and motorcycle accidents in Britain between 1951 and 1980. The level of risk (calculated as motorcyclist fatalities per motorcycle kilometre travelled) has fallen, but this effect has been overwhelmed by changes in motorcycle...

The motorcycle riders are subjected to extreme vibrations due to the vibrations of its engine, improper structural design of the motorcycle and the bad road conditions. The literature review reveals that the vibrations are most hazardous to the health if it exceeds the limit. The experiments were conducted to measure the magnitude of the vibrations acting on the rider during motorcycle riding u...

Plastic oil is the result of conversion plastic waste into fuel oil. The use not directly at 100% use, but it necessary to have right dose so that can be used as a mixture. method in this study experimental research, namely several variations are carried out successively same subject and determine performance exhaust emissions on motorcycle with mixture Pertamax has CP10 code (pertamax 90% + oi...

Sedentary transport is known to adversely affect health. Few studies have focused on motorcycle use. This study examines the association of motorcycle use with overweight in urban adults in Taiwan. Cross-sectional data from 1069 Taiwanese adults aged 20-64 years in three urban cities were collected in 2015. Data on self-reported body mass index, time spent in motorcycle use, lifestyle behaviora...
