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...

Driver-assistance systems that monitor driver intent, warn drivers or assist in vehicle guidance are all being actively considered. This paper present computer vision system designed for recognizing road boundary and a number of objects of interest including vehicles, pedestrians, motorcycles and bicycles. The system is designed using Hough transform and Kalman filters to improve the accuracy a...

Motorcycles generate different sound patterns under dissimilar working conditions. The generated sound pattern gives a clue of the fault. Mainly the parts of the engine that lead to change in sound are cylinder kit, crank, timing chain, and valve. The parts of the exhaust system that change sound under fault are muffler and silencer. In this study, we analyze the sound signals produced by motor...

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...

Along with the development of economy and society speedy increasing number personal vehicles, especially motorcycles, many cities in developing countries like Hanoi (Vietnam) are facing transportation problems, notably traffic accidents involving motorcyclists. Motorcycle caused by main human-error factors, could be considered as typical grey system features complexity imperfect information. In...
