The Abbreviated Injury Scale scores of subgroups of patients were used to evaluate patterns of injury for helmeted andunhelmeted riders.As expected, the incidenceofhead injury was higher among the unhelmeted riders (63.81%) than among the helmeted riders (38.95%). In comparison, helmeted riders had higher rates of thoracic injury (47.76%) and extremity injury (80.18%) thandidunhelmeted riders (...

The data reported here are drawn from two detailed, in-depth studies of motorcycle accidents in which trained investigators collected extensive evidence on-scene immediately after the crash. This paper compares helmeted and unhelmeted motorcycle riders on a per-accident basis for fatality rates, for the frequency of serious (AIS>2) brain injuries among survivors or for what is referred to here ...

OBJECTIVE To study and quantify the effect of factors related to the riders of powered two-wheelers on the risk of injury accident involvement. METHODOLOGY Based on national data held by the police from 1996 to 2005, we conducted a case-control study with responsibility for the accident as the event of interest. We estimated the odds ratios for accident responsibility. Making the hypothesis t...

To design adequate measures for enhancing riders' safety, a necessary first step is to understand the riders' visual scanning strategies under different traffic conditions. This paper presents the preliminary analysis of eye tracking data collected by three riders in the Athens metropolitan area, riding along urban arterial motorways and along an undivided urban road. Apart from the fixation du...

Maintaining equilibrium while riding a horse is a challenging task that involves complex sensorimotor processes. We evaluated the relative contribution of visual information (static or dynamic) to horseback riders' postural stability (measured from the variability of segment position in space) and the coordination modes they adopted to regulate balance according to their level of expertise. Rid...
