OBJECTIVE To explain a reduction in pedestrian-motor vehicle crashes in Arkhangelsk, Russia, in 2005-2010. STUDY DESIGN Retrospective ecological study. METHODS For 2005-2010, police data on pedestrian-motor vehicle crashes, traffic violations, and total motor vehicles (MVs) were combined with data on changes in national road traffic legislation and municipal road infrastructure. Negative bi...

This letter constitutes the interim report of the Transportation Research Board Committee for the Study of a Motor Vehicle Rollover Rating System. This committee was convened in response to a request from the Congress asking the U.S. Department of Transportation to fund a study by the National Academy of Sciences on motor vehicle rollover. The main objectives of this report are (1) to present t...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. speed identification is needed for the induction motor drives. however, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. ther...

The goals of this paper are twofold: we describe common features in data sets from motor vehicle insurance companies and we investigate a general strategy which exploits the knowledge of such features. The results of the strategy are a basis to develop insurance tariffs. The strategy is applied to a data set from motor vehicle insurance companies. We use a nonparametric approach based on a comb...

A better understanding of the risk involved in riding different sizes and types of motor vehicles is required to make informed decisions regarding a reasonable level of protection for wheelchair riders. Wheelchair rider accident information that can be used to estimate risk is quite limited. This paper reviewed the resources available, including the National Electronic Injury Surveillance Syste...

(a) Interim Report: urgent measures that should be implemented to prevent harmful air pollutants (October 18, 1996). (b) Report No. 2: measures to reduce exhaust emissions from motor vehicles that utilize gasoline or liquefied petroleum gas (LPG) as fuel, hereafter they are referred to as gasolineor LPG-fueled motor vehicles, respectively, and also special motor vehicles, which are the largeand...

As one of the major analysis methods, statistical models play an important role in traffic safety analysis. They can be used for a wide variety of purposes, including establishing relationships between variables and understanding the characteristics of a system. The purpose of this paper is to document a new type of model that can help with the latter. This model is based on the Generalized War...

Developing sound or reliable statistical models for analyzing motor vehicle crashes is very important in highway safety studies. However, a significant difficulty associated with the model development is related to the fact that crash data often exhibit over-dispersion. Sources of dispersion can be varied and are usually unknown to the transportation analysts. These sources could potentially af...
