The objective of this article was to identify the association between motorcycle deaths and variables related to Samaja's theory of social reproduction in the period 2000-2005 in the state of Pernambuco. An ecological, case-control study was carried out, with municipalities as the unit of analysis. Cases were defined as the 20% of municipalities with the highest local empirical Bayesian coeffic...
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...
Submit Manuscript | http://medcraveonline.com were 468 men (76.09%) and 147 women (23.91%), and the 21-30 age group was the most representative with (n=195, 31.70%) case. Students were the most affected (n=270, 43.91%) on traders (n =142, 23.09%). Motorcycle drivers (n=304, 49.44%) and motorcycle rear passengers (n=175, 28.45%) were the most affected. The most common types of accidents were mot...
The use of stated preference (SP) surveyed data of the motorcycle taxi riders in Bangkok and its vicinities has been investigated in this paper. A research aim is, preliminary, detailed in terms of the affect factors of the motorcycle between the internal combustion engine vehicle and the electric vehicle for public transport. With 1,200 surveyed data, the results show that 91.1% of the taxi ri...
Over recent years, researchers have used full-scale motorcycle crash tests in the field of road safety research to simulate different types of crash technique and scenario. This study focuses on the development of laboratory-based motorcycle crash tests. A moveable barrier, designated as a ‘trolley’ in this study, is designed, developed and implemented in a laboratory-based motorcycle crash tes...
OBJECTIVE To estimate the impact of a mandatory motorcycle helmet law in Taiwan. METHODS Taiwan passed a mandatory helmet law in June 1997. Data were collected retrospectively from police reports, which include hospital data, to compare six months pre-law June to November 1996) with the same six months post-law (June to November 1997). RESULTS Motorcycle fatalities decreased 14% after the i...
Increasing the demand for electric vehicles, makes the manufactures to concentrate on the research of new energy storage devices, electro motors, and power electronic devices. The main subject in designing an electric motorcycle with four-phase AFPM and its full wave converter is to select suitable energy storage system and add on turbo-acceleration mechanism. Choosing the suitable energy stora...
Motorcycle helmets have been reported to reduce the risk of death and head injuries following motorcycle accidents. The aim of this descriptive prospective study was to determine the injury outcome among helmeted and non-helmeted motorcyclists and passengers at a tertiary hospital in north-western Tanzania. A total of 654 patients involved in the motorcycle accident were studied. Of these, 468 ...
OBJECTIVE To analyze the spatial distribution of mortality due to motorcycle accidents in the state of Pernambuco, Northeastern Brazil. METHODS A population-based ecological study using data on mortality in motorcycle accidents from 01/01/2000 to 31/12/2005. The analysis units were the municipalities. For the spatial distribution analysis, an average mortality rate was calculated, using death...
INTRODUCTION Motorcycle passengers comprise a considerable proportion of traffic crash victims. During a 5 year period (2006-2010) in Iran, an average of 3.4 pillion passengers are killed daily due to motorcycle crashes. This study investigated the main factors influencing crash severity of this group of road users. METHOD The Classification and Regression Trees (CART) method was employed to ...
