William Haddon and the escape of tigers…

 

William Haddon (in the picture)  was the first director of the National Traffic Safety Highway Administration (NHTSA) and of the Insurance Institute of Highway Safety (IIHS) in the United States. He is credited with a paradigm change in the prevention of road traffic deaths and injuries moving from an “accidental” or “pre-scientific” approach to an etiologic one. This paradigm will result in the very well known (and frequently misunderstood) “Haddon Matrix”, which is intrinsically related to the Safe Systems approach.

A major piece of his contribution to the field was to express very clearly that “there is no logical reason why the rank order (or priority) of loss-reduction countermeasures (…) must parallel the sequence, or rank order, of causes contributing to the result of damaged people or property”.

Even if the above affirmation may seem shockingly, please read the paper Haddon 1970- On the escape of tigers , published in the American Journal of Public Health in 1970 and continue thinking about the problem.

SENIORS project testing at the Impact Laboratory of the University of Zaragoza

During the last weeks, the Impact Laboratory (I3A) of the University of Zaragoza has completed a series of sled tests including the THOR dummy, young and elderly volunteers and Post Mortem Human Surrogates that will be used within the SENIORS project. We were fortunate to count with the assistance of colleagues from some of the partners of the SENIORS consortium. In the picture from left to right:

Visita de ANESDOR a las instalaciones del Laboratorio del Impacto

AnesdorEl pasado miércoles 18 de Mayo, representantes de ANESDOR (Asociación Nacional de Empresas del Sector de Dos Ruedas) se reunieron en Technopark (Motorland) y tuvieron la oportunidad de visitar las instalaciones del Laboratorio de Impacto (I3A) de la Universidad de Zaragoza. Entre otras cosas, el director del laboratorio (Mario Maza) tuvo la oportunidad de explicar algunos de los actuales proyectos que se estan llevando a cabo dentro de las actividades del FIM Institute, del que forma parte el Laboratorio de Impacto.

En la fotografía, Mario Maza explica la metodología para la realización de ensayos de impacto sobre barreras.

Alava Ingenieros and Humanetics visited the Impact Laboratory

Alava&HumaneticsAlava Ingenieros and its techonological partner Humanetics visited the facilities of the Impact Laboratory (I3A) of the University of Zaragoza on May 18th, 2016. Humanetics presented the new FE model developments of the Q family and THOR and the road map to the introduction of new dummy models both in NCAP and NHTSA testing programs.

The researchers of the Impact Laboratory showed some of the latest results obtained in the study of occupant kinematics in nearside oblique impacts.

SAFE 2 WHEELERS workshop: program ready

Logo

The final agenda of the worskhop on Traffic Environment, Primary and Secondary Safety of Powered Two Wheeled vehicles is now available for download. Researchers at the Impact Laboratory of the University of Zaragoza are excited about joining the international community to share latest knowledge about motorcyclist protection. If you want to know more details about the program, you can download it here.

Researchers from the Impact Laboratory of the University of Zaragoza will participate in the upcoming SAFE2WHEELERS workshop

IMG_9685Mario Maza and Oscar Juste-Lorente will participate in the workshop on Traffic Environment, Primary and Secondary Safety organized within the COST TU1407 SAFE2WHEELERS. The workshop will be held at the Johannes Kepler University in Linz (Austria). Mario and Oscar will be presenting about the safety performance of roadside barriers in racing tracks and about how existing regulations drive helmet design.

For more information, please visit the website of the project SAFE2WHEELERS.

If you are interested in attending the workshop, you can contact Francisco Lopez-Valdes at safe2wheelers@uniresearch.com

IRCOBI Council inviting full manuscripts for the Malaga 2016 Conference

IRCOBI_logoThe Council of IRCOBI met on Jan. 21 and 22 to review and discuss al the abstracts submitted to the 2016 Malaga Conference. After a thorough discussion of each of them due to the great quality of the submissions, the Council came up with the final decision of the ones that will be invited for submission. The 2016 Conference promises to be an exciting scientific and social event!

And if you are a junior engineer in training or a graduate student, make sure you stay tuned and look for upcoming opportunities of applying to scholarships to attend the Conference!

Check out the IRCOBI website for more information about the Conference.

Nearside Oblique Impacts

DSC_1237SAFER, Autoliv Research and the Impact Laboratory of the Institute of Engineering Research of the University of Zaragoza are collaborating in a joint investigation on the kinematics of restrained front occupants in nearside 30 degree impacts at moderate speeds. The project includes a series of sled tests with the THOR dummy that were performed in July 2015 and three tests with Post Mortem Human Surrogates. Ethical approval from CEICA (Commission for the Ethics Assessment of Clinical Trials of Aragon, the official regional commission in charge of reviewing research projects that involve Ethical issues in Aragon)  was granted in October 2015, prior to the start of the PMHS sled test.

The project seeks to characterize the kinematics of occupants of the front seat to optimize the design of advanced restraint systems that can be effective in this kind of impacts. Results will be available during the first quarter of 2016.
