Los investigadores de distintos países que trabajan sobre este tema, han reportado cambios en los patrones de conducción, el Federal Test Procedure, que fue de los primeros ciclos que se desarrollaron (inició a mitad de los 60&#8217;s) ha sufrido cambios desde muchos, años atrás para estar actualizado como se menciona en EPA (1998). De igual forma, algunos países de la Unidad Europea han desarrollado diferentes ciclos de manejo, y al compararlos con el EURO93, se comenta que debe actualizarse, ya que no satisface los requisitos para reproducir las condiciones de conducción reales, principalmente en zonas urbanas (André M. Robert et al., 2001). Hoy en día, no sólo son preocupantes las emisiones que afectan directamente a la salud, sino también el uso inmoderado de los combustibles, ya que además de consumirse productos no renovables, se generan grandes volúmenes de uno de los gases de efecto invernadero, el CO2. Debería existir un compromiso real de todos los países del orbe, principalmente de aquellos altamente industrializados para que reduzcan la generación de CO2, y como uno de los sectores que consumen grandes volúmenes de energéticos es el del auto transporte, es inquietante saber qué se está haciendo al respecto. En el presente artículo se mencionan algunos puntos de vista acerca de estas actividades.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract A review of the specialized literature over driving cycles which have been developed in many cities and countries, allow to make some reflections over this topic, and to comment about the experimentation activities (on the roads, motorways, in the laboratory and by computational models). The researchers that work in this field have reported substantial changes in the driving patterns. Federal Test Procedure was one of the first cycles to be developed (it was known in the decade of the 60&#8217;s) and it has suffered changes from many years ago in order to be modernized EPA (1998). In the same way, many countries of the European Comunity have developed different driving cycles and when these have been compared with EURO93, it was commented that the actual cycle should be modernized because it doesn&#8217;t reproduce the real world conditions, mainly in urban areas (André M. Robert et al., 2001). Nowadays not only should we be concerned by the emissions that directly affect health, but also the exaggerated fuel consumption. In addition to wasting non-renewable products, it generates large volumes of one of the greenhouse gases, CO2. A commitment exist in all countries, mainly those which are highly industrialized to reduce the generation of CO2, and as Road Transport is one of the sectors that consumes largest volumes of energy it&#8217;s interesting to know what is being done in this respect. In this paper some points of view are mentioned concerning the researchers (from various countries) about the activities that Road Transportation develop to decrease fuel consumption and emissions, and therefore comply with the goals of Kyoto.]]></p></abstract>
