Work Package 3 of SafetyNet deals with Safety Performance Indicators. They measure the operational conditions of the road traffic system. Work Package 3 deals with seven topics: alcohol and drug use; speeds; protective systems; daytime running lights; vehicles; road; trauma management. This deliverable concerns the contribution of Work Package 3 to the first SafetyNet conference, which was held in Prague on May 10 and 11, 2006. Each topic prepared a poster with an overview of the state-of-play. In this document, these posters are assembled. Each topic has a preferred indicator, which can be used for measuring safety performance across countries. This indicator is accompanied by requirements that should be met by the data, in order to be able to calculate the indicator. For most tasks, values could be calculated for the indicators by using the available data. Data are not available for all countries and/or all topics.

This report describes the first phase activity of the Portuguese group in the Precast Structures EC8 research projet. The Portuguese group is composed by Laboratório Nacional de Engenharia Civil (LNEC) and the Civibral, S.A. Precast Company.In this phase, seismic test were made in the LNEC

This report is one of three area reports that examine the road safety performance of the nine countries participating in the SUNflowerplus project. This area report compares the road safety situation of the Southern countries of Greece, Portugal and Spain (including a separate analysis for the Spanish autonomous region of Catalonia).The aim of this report is to identify the major road traffic risk differences between Southern European countries based upon a comparative approach initially applied by the SUN (Sweden, United Kingdom & the Netherlands) countries, and focussed on the analysis of fatalities by users of different modes of road transport.The method for comparing the Southern countries has been developed from that of the original SUNflower report (SWOV, 2002), and is reflected in the organisation of the chapters:- Description of national policy and plans. - Description of the transport context.- Fatalities by road user mode and collisions between modes.- Case studies for: drink-driving, seat belts, young drivers, speed management, pedestrians, mopeds and motorcycles.In some cases (for example, young drivers and pedestrians), the indicators used to compare the situation in the Southern countries are common to those reported in the SUN and Central areas. In other cases (for example, speed management) the situations are very different and there is less scope for comparison.SUNflower+6 compares statistics for road fatalities in terms of fatalities within 30 days of the accident. In all three Southern countries, the figures are based on national factors applied to police data recording deaths within 24 hours. In producing indicators, various efforts to improve data systems have been detected. In general, a greater use of information and communications technologies could improve the process of data registration as well as facilitating improved analysis.All three countries (and the autonomous region of Catalonia) have published a plan covering a period of three or more years (including the current year of 2005) that sets quantified targets for a reduction in the number of road accident fatalities. Such progress in road safety planning is a relatively new aspect of road safety activity in the Southern countries studied. The targeted reductions for Portugal are even more ambitious than those of the EU White Policy paper proposing a halving in road deaths by 2010, whilst those for Spain and Catalonia are in line with the European overall projection and those for Greece are more modest.

O presente relatório foi elaborado no âmbito do estudo: "Avaliação da Eficácia das Medidas de Minimização de Impactes Ambientais". Este trabalho, para as Estradas de Portugal, compreende quatro aspesctos ambientais alvo de medidas de minimização de impactes no âmbito da aprovação de projectos rodoviários - as águas de escorrência de estradas, a fauna, o ruído, o solo. Os resultados globais da primeira fase do estudo foram publicados num Relatório conjunto. Porém a equipa que estuda os Sistemas de Tratamento de Águas de Escorrência sentiu a necessidade de sistematizar, num documento específico, todas as premissas e raciocínios que serviram de base ao desenvolvimento do trabalho.Constam deste relatório os seguintes capítulos:(1) Introdução, (2) Objectivos e Metodologia, (3) Aplicação da Metodologia ao IP6 Peniche/IC1, (4) Análise Crítica da Adequação da Metodologia e finalmente, (5) Continuação do trabalho.

The present report addresses the first twelve months of LNEC participation in LESSLOSS

The dynamics of rigid bodies was studies by long time, because this phenomenon is important in the seismic security of some types of structures. However, there are few experimental studies. This job shows the experimental test carried out at the Laboratório Nacional de Engenharia Civil (LNEC) of Portugal. Four blue granites stones were tested, each one with different geometrical characteristics, under harmonic and random motions.A numerical simulation was carried out with the Discrete Element Method (DEM). This method has shown to be a good tool in the study of the dynamics of rigid bodies. It was proposed a new methodology to find the parameters of the DEM by using the parameters of classical theory.

The project LESSLOSS

GeneralRoad safety can be assessed in terms of the social costs of crashes and injuries. However, simply counting crashes or injuries is an imperfect indicator of the level of road safety. When crashes occur it is the

The SUNflower+6 project is based on a comparative study regarding road safety in nine countries and one autonomous region from the EU. These countries are divided into three groups: -
