OBJECTIVE The aim of this study was to evaluate whether the low visibility of motorcycles is the result of their low cognitive conspicuity and/or their low sensory conspicuity for car drivers. BACKGROUND In several cases of collision between a car and a motorcycle, the car driver failed to detect the motorcyclist in time to avoid the collision. METHOD To test the low cognitive conspicuity h...

This study evaluates the association of universal helmet laws with U.S. motorcyclist fatality rates from 1993 through 2002 using climate measures as statistical controls for motorcycling activity via quasi-maximum likelihood generalized linear regression analyses. Results revealed that motorcyclist fatalities and injuries are strongly associated with normalized heating degree days and precipita...

OBJECTIVES We assessed the implications for motorcyclist safety of recent repeals of universal helmet laws in 6 US states. METHODS We examined cross-sectional time-series data from the 50 states and the District of Columbia for the period 1975 through 2004. RESULTS On average, when compared to state experience with no helmet mandate, universal helmet laws were associated with an 11.1% reduc...

Background Road traffic accidents are commonly encountered incidents that can cause high-intensity injuries to the victims and have direct impacts on the members of the society. Iran has one of the highest incident rates of road traffic accidents. The objective of this study was to model the patterns of road traffic accidents leading to injury in Kurdistan province, Iran. Methods A time-serie...

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 ...

Results: Crash frequencies are tabulated with particular reference to (a) different ages of motorcyclist, (b) the metropolitan versus non-metropolitan distinction, (c) single and multiple vehicle crashes, and (d) gender of motorcyclist. Each analysis showed a similar trend in crash frequency for age groups, with younger riders (16-29yrs) declining in crash frequency, the intermediate age group ...

BACKGROUND Successfully increasing cycling across a broad range of the population would confer important health benefits, but many potential cyclists are deterred by fears about traffic danger. Media coverage of road traffic crashes may reinforce this perception. As part of a wider effort to model the system dynamics of urban cycling, in this paper we examined how media coverage of cyclist fata...

In relative terms, Spanish motorcyclists are more likely to be involved in crashes than other drivers and this tendency is constantly increasing. The objective of this study is to identify the factors that are related to being an offender in motorcycle accidents. A binary logit model is used to differentiate between offender and non-offender motorcyclists. A motorcyclist was considered to be of...
