The electric vehicle (Ve) is struck by their low autonomy. To remedy this problem, we opted for the choice of a converter structure in electromagnetic switch, since it has no power dissipation in switching and conduction. The development of a control law of motorization continues saving energy and its implementation under the environment of MATLAB / SIMULINK, led to the scientific results of hi...

In this paper, we examine basic transportation and land use characteristics from a selection of cities in Africa, China, Latin America, and South Asia. By definition, poorer than their industrialized country counterparts, developing cities are in a stage of rapid dynamism. From a mobility perspective, perhaps the single most influencing factor is motorization – the growth in motor vehicle owner...

background: injuries and deaths from road traffic crashes are one of the main public health problems throughout the world. this study aimed to identify determinants of fatality traffic accident in iran for the twenty-span year from 1991 to 2011. methods: a time series analysis (1991-2011) was used to examine the effects of some of the key explanatory factors (gdp per capita, number of doctors p...

Cultural paradigms determine both how we view road safety and the actions we take to improve it. While there may be many different competing paradigms for dominance, one paradigm can be seen as dominant. The dominant paradigm has changed a number of times over the century of motorization. The Finnish scholar, Valde Mikkonen (1997) has characterized conceptual development in road safety as a slo...

the paper presents the optimization results for several electrical machines dedicated for powered electric wheel-chairs. The optimization, using the Hook-Jeeves algorithm, was employed based on a design approach which takes into consideration the road conditions. Also, through numerical simulations (based on finite element method), the analytical approach was validated. The optimization approac...

This paper compiles, evaluates and analyses information from different data sources on accidents and health, road transport and economic performance in a comprehensive manner to assess the size and impact of road accidents and injuries in regions under increasing motorization. Strategies based on global road safety improvement experiences are presented. In addition the paper aims at discussing ...
