ANÁLISIS DE SENSIBILIDAD EN EL CÁLCULO DE EMISIONES CONTAMINANTES DEL TRÁFICO DE MERCANCÍAS EN EJES DE TRANSPORTE

Blanca del Valle Arenas Ramírez; Jorge Ruiz Porro; José Manuel Mira McWilliams; José María López Martínez; Francisco Aparicio Izquierdo

La competitividad en el transporte de mercancias espanol y mundial, junto con la preocupacion creciente por la reduccion de emisiones, ha provocado que se preste una gran atencion a la mejora de su eficiencia, tanto desde el punto de vista logistico como el medioambiental. Por ello, el trasvase modal tiene una relevancia creciente en las administraciones y en investigacion. En este trabajo se desarrolla un analisis de sensibilidad sobre un codigo de ordenador de simulacion estocastica, que estima la distribucion de probabilidad de las emisiones que se dejan de producir en la carretera como consecuencia del trasvase modal de mercancias al ferrocarril. El modelado estadistico proporciona el valor anadido esencial de la cuantificacion de las incertidumbres y comprende varias etapas que posteriormente se acoplan mediante el metodo de Monte Carlo, implementado en un codigo de simulacion escrito en lenguaje abierto R. El analisis de sensibilidad se realiza a traves de un experimento computacional cuyos resultados se analizan mediante la tecnica ANOVA, para estudiar el efecto, sobre las emisiones, de cambios en las distribuciones de probabilidad de las variables que determina las etapas del modelo, tanto de forma individual (efectos principales) como conjunta (interacciones). La metodologia se aplica como ilustracion al eje Madrid-Guipuzcoa para la estimacion de consumos y de las emisiones de CO, NOx, HC y de material particulado (PM).

Van Traffic Accident Analysis. A Holistic Approach

Blanca del Valle Arenas Ramírez; Javier Páez Ayuso; José Manuel Mira McWilliams; Felipe Jiménez Alonso; Arturo Furones Crespo; Francisco Aparicio Izquierdo

From 2003 on, the numbers of accidents and victims have decreased significantly in Spain: the number of deaths was in 2010 54 % below that of 2003. This has been to a great extent the results of several safety policy measures such as the penalty point system, surveillance and control campaigns and a considerable increase in the media of road safety-related issues. However, accidents with involvement of vans (LGV’s less than 3500 kg) have not followed this trend, and thus the contribution of this kind of vehicles to the global figures has risen. Within this context, INSIA has conducted an ambitious research project, developed with the purpose of an integrated analysis of the different factors which can explain the accidental behavior of this kind of vehicles. In this paper analyze in greater depth the validity of one of the initial hypothesis: “vans may have a different dynamic behavior from passenger cars, and thus accident rates may be higher if they are driven like a passenger car”. The basis of the working hypotheses are essentially related to the behavior of the vehicle with respect to safety distances, reaction times and braking capacities of the vehicle behind, and on the influence of loads.

The Use of Trivial Reductions of Dimensionality in the Propagation of Uncertainties: A Radioactive Contaminant Transport Model Example

Ricardo Bolado Lavin; José Manuel Mira McWilliams

In some engineering problems solved through stochastic simulation, the models used depend on a set of fundamental parameters that may be combined in easy ways to create a smaller set of composed parameters. We show that is more profitable from a statistical point of view sampling from the reduced set of uncertain parameters and using variance reduction techniques than sampling from the original one.
