background: all over the world motorcycle accident are one of the major causes of road death and injury. this study aimed to determine the pattern of motorcycle fatal accidents in mashhad-iran. methods: this descriptive cross-sectional study was carried out in 2006 to analyze the epidemiological pattern of the mo­tor­cycle accident in mashhad, north-eastern iran . three hundred fifty cases of m...

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...

This paper aims at providing solutions that would improve safety and riding experience. To ensure the rider uses a helmet, bike wont start unless is wearing helmet. The also proposes solution to get live location of as well using this disable horn in no honking zones. With help different sensors mounted on proposed system can detect an accident inform emergency contact numbers. further efficien...

GRANGE, J.T., J.A. BODNAR, and S.W. CORBETT. Motocross medicine. Curr. Sports Med. Rep., Vol. 8, No. 3, pp. 125Y130, 2009. Motocross is an increasingly popular but high-risk sport. This article reviews the history of motocross, the relevant medical literature, the unique medical issues, safety equipment, and the expert recommended approach to providing support for such events. Assessment of an ...

This study investigated electric-scooter (e-scooter) rider behaviors and preferences to inform ways increase safety for e-scooter riders. Data was collected from 329 riders via two online one in-person survey. Survey questions considered roadway infrastructure preferences, perceptions, helmet-wearing behavior. Protected bike lanes were more commonly indicated as the safest (62.4%) but less like...

In a cycling time trial, the rider needs to distribute his power output optimally to minimize the time between start and finish. Mathematically, this is an optimal control problem. Even for a straight and flat course, its solution is non-trivial and involves a singular control, which corresponds to a power that is slightly above the aerobic level. The rider must start at full anaerobic power to...

The authors studied the interaction between rider and horse by measuring their ensemble motions in a trot sequence, comparing 1 expert and 1 novice rider. Whereas the novice's movements displayed transient departures from phase synchrony, the expert's motions were continuously phase-matched with those of the horse. The tight ensemble synchrony between the expert and the horse was accompanied by...

In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...
