The European Union's road safety policies set out in the White Paper on Transport seek to half the number of deaths in road accidents between 2000 and 2010, but do not specify how to achieve this objective.
A group of researchers from the University of Almería has now devised a mathematical method for carrying out these calculations, which has been published recently in the scientific journal Accident Analysis and Prevention.
"It is a novel methodology that is easy to apply, meaning it is possible to calculate the weighted coefficients for reducing accident rates in various geographical areas, by using an inverse logarithmic formula", Alfredo Tolón, co-author of the proposal and an engineer in the UAL's Engineering Projects Department, tells SINC.
The weighting was carried out for the 25 countries of the EU and the 50 Spanish provinces, with that the greatest effort to meet the 2010 objectives required in those countries and provinces with the highest mortality rates in 2000. In that year, 52,536 people died in road traffic accidents in Europe, of whom 4,295 were Spanish.
The researchers also compared the real evolution of road death data between 2000 and 2006 in order to check the validity of the methodology. The study shows there is a high correlation between the series of real data and those indicated by the model. Countries such as Luxembourg, Portugal, France, Denmark and Malta have even exceeded their assigned percentage.
Lithuania, Hungary, Estonia and Slovakia, on the other hand, showed the worst results, "and the projections don't give much cause for optimism about them meeting the European objective". Given this outlook, the team has also calculated the weighted accident reduction rates for the 25 countries of the EU in 2015, based on data from 2006, in order to obtain an overall reduction of 60%.
The greatest effort: Huelva, Salamanca and Malaga
The Spanish provinces least likely to meet the targets on reducing road deaths are Huelva, Salamanca and Malaga. Vizcaya is the only one in which the number of victims in 2006 fell by more than the figure proposed by the study (61% compared to the 44.4% forecast). Other provinces making "significant progress" are Guipúzcoa, Tenerife, Navarre, Soria, Barcelona, Álava and Madrid.
"Over recent years, however, there has been evidence of important progress in Spain, and by 2010 we may not be far off achieving the right level of reduction in road accident deaths", says Tolón. According to data from the DGT (Directorate General for Traffic), 2,181 people died on Spanish roads in 2008.
In any case, the engineer stresses the importance of this kind of study "in order to open up the debate about the need for weighting in the application of global policies and to establish pragmatic objectives for reducing road accident rates".

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
