When dealing with road safety in Africa, one should bear in mind that road safety problems need to be seen in their context as the solutions proposed to address them. While it is relevant to consider international good practices, African stakeholders should become owners of the interventions addressing their problems and take the responsibility for developing and implementing the appropriate solutions, taking advantage of suitable technical assistance, if needed. Based on these considerations, in this paper, a presentation is made of the process used in the European research project SaferAfrica to define suitable Safe System projects in Africa. This project aims at supporting policymakers and stakeholders with evidence on critical risk factors, related actions, and good practices drawn from high-quality data and knowledge. In the project, road safety and traffic management capacity reviews at the country level were carried out in five countries (Cameroon, Burkina Faso, Tunisia, Kenya, and South Africa), following the World Bank guidelines. After conducting such a capacity review, these guidelines recommend the preparation and implementation of Safe System projects,

Introduction: Roadway departure (RwD) crashes, comprising run-off-road (ROR) and cross- median/centerline head-on collisions, are one of the most lethal crash types. According to the FHWA, between 2015 and 2017, an average of 52 percent of motor vehicle traffic fatalities occurred each year due to roadway departure crashes. An avoidance maneuver, inattention or fatigue, or traveling too fast with respect to weather or geometric road conditions are among the most common reasons a driver leaves the travel lane. Roadway and roadside geometric design features such as clear zones play a significant role in whether human error results in a crash.in a crash.Method: In this we used mixed-logit models to investigate the contributing factors on injury severity of single-vehicle ROR crashes. To that end, we obtained five years

School commuting with public transportation (PT) and shifting away from private cars remains a challenge, especially for transport planners. From behavioral and cultural viewpoints, car dependence has not yet been reversed in many cities. Actions to promote the shift to PT should be multidisciplinary and multi-instrumental to increase PT adoption and achieve more sustainable mobility. There is a lack of strategic alignment between the different stakeholders involved in school commuting of children (parents, school, PT operators) and empirical studies sustaining the effectiveness of actions to shift away from the car. Moreover, PT behavioral aspects are still poorly researched from a marketing perspective. This research aims to help fill the gap by implementing actions related to the 4Ps of the marketing mix (product, place, price, promotion). Ten schools in the Lisbon Metropolitan Area were involved in those actions and then surveyed (1,760 survey participants) to evaluate the impact on their behavioral change, that is, to start going to school with PT. The study explores the impact of a set of marketing events on the time duration before children shift to PT when commuting to school, with a hazard-based duration model. Results suggest that to promote school commuting with PT, it is necessary to characterize the school community before commencing any mobility-oriented intervention, particularly concerning sociodemographic attributes and mobility patterns. These are critical information to design marketing actions better and to adapt and improve the quality of PT vehicles and services that operate to and from schools.

This paper is built around a research project developed with the support of the Regional Planning Authority of the Algarve Region in Portugal which assessed mobility patterns covering all modes of transport using heterogeneous data sources (time-series data). Data mining techniques helped to identify limitations in some data sets. The econometric analysis showed that integrated autoregressive models and moving averages for series with seasonality were successful in the prediction of passenger flows using time-series data gathered by the regional authority from transport operators and other entities. Results from the analysis are useful to support a strategy to reverse current trends on continued car growth (along with public transport decrease) and to devise policy measures to enable a sustainable mobility path towards decarbonisation and social equity goals until 2030.

Under the Safe System framework, Road Authorities have a responsibility to deliver inherently safe roads and streets. Addressing this problem depends on knowledge of the road network safety conditions and the number of funds available for new road safety interventions. It also requires the prioritization of the various interventions that may generate benefits, increasing safety, while ensuring that reasonable steps are taken to remedy the deficiencies detected within a reasonable timeframe. In this context, Road Safety Inspections (RSI) are a proactive tool for identifying safety issues, consisting of a regular, systematic, on-site inspection of existing roads, covering the whole road network, carried out by trained safety expert teams.This paper aims to describe how topic modelling can be effectively used to identify co-occurrence patterns of attributes related to the run-off-road crashes, as well as the corresponding patterns of road safety interventions, as described in the RSI reports. We apply latent Dirichlet allocation (LDA), a widespread method for fitting a topic model, to analyse the topics mentioned in RSI reports, divided into two groups: problems found; and proposed solutions. For this study, 54 RSI gathered over six years (2012 - 2017) were analysed, covering 4011 km of Irish roads.The results indicate that important keywords relating to the

Roadway departure (RwD) crashes, comprising run-off-road (ROR) and cross-median/centerline head-on collisions, are one of the most lethal crash types. Nationwide, from 2014 to 2016, annual RwD crashes accounted for 53% of all motor vehicle traffic fatalities. Several factors may cause a driver leave the travel lane, including an avoidance maneuver and inattention or fatigue. Roadway and roadside geometric design features (e.g., lane widths and clear zones) play a significant role in whether human error results in a crash. In this paper, we present a hazard-based duration model to investigate the distance traveled by an errant vehicle in a run-off-road crash, the stopping hazard rates, and associated risk factors. For this study, we obtained five years' (2010

Stepping away from traditional crash-based road safety measurements, several safety performance indicators (SPI) have been proposed in the past few years. SPI can incorporate quantitative and qualitative information on specific aspects that are known to have influence in the safety levels and, not only measure the influence of various safety interventions but also enable comparisons between different road systems. This paper presents the results of the application of a road network SPI to the entire Portuguese road network. This SPI aims at evaluating at the network level, if the connections between urban centres within a region are made by the adequate type of roads regarding generic safety criteria. To this end, the connections to be assessed were classified into pre-defined theoretical safety classes, based on the population of the connected urban centres. Then, the observed safety class of these connections was assessed according to the characteristics of their cross-section and associated road environment of the existing connection between the two urban centres. If the observed class is ensured by a road of higher or equal class than the pre-defined theoretical level in all its extension, the link is considered to be of the appropriate class. For each connection, the results of its evaluation are expressed as a binary value: 0 when the class is not appropriate; and 1 when it is appropriate. The evaluation results are weighted by the road length and aggregated by connection class and throughout the whole road network. The results show a satisfactory network configuration with an SPI of 94% connections with class equal to or higher than the adequate for the type of connection between urban centres they established. The above insights can help in the identification of potential operational inconsistencies that may require safety-related interventions and used for international benchmarks against existing SPI evaluations.

A Economia dos Transportes e do Ambiente constituem bases para a fundamentação teórica dos métodos de avaliação económica de impactos ambientais dos transportes. Todavia, ainda não existem recomendações sobre qual a metodologia de avaliação económica a utilizar na monetarização dos vários impactos. Neste contexto, são várias as questões em investigação, tendo como objectivo contribuir para a melhoria da eficiência da avaliação ambiental estratégica de planos e programas de transporte:- O conhecimento actual permite que todos os impactos dos transportes possam ser monetarizados de igual forma?- Que tipos de impactos devem ser considerados na avaliação ambiental estratégica no sector dos transportes? - Que métodos de avaliação podem ser recomendados para cada impacto?- Quais os futuros desafios em matéria da avaliação ambiental estratégica de planos e programas de transportes?Será abordado o caso dos custos externos ambientais do ruído de tráfego aéreo.

The Interactive Highway Safety Design Model (IHSDM) is a software tool for evaluating safety and operational effects of alternatives in highway projects, which is available through the US Federal Highway Administration (FHWA). IHSDM can be applied in the design of new highways and in the major redesign of existing highways. The software contains five modules, intended for the evaluation of measures describing relevant aspects of the expected safety and operational performance of a highway design. Three of these modules are potentially relevant for use outside the US: the Crash Prediction Module, the Design Consistency Module, and the Traffic Analysis Module.A procedure for the detection of inconsistent horizontal curves in single carriageway rural roads of the National Road Network and the improvement of their safety records was developed at the National Laboratory of Civil Engineering (LNEC) for application in Portugal, using driver behaviour and safety data collected in the national context. The procedure may be applied automatically using the dedicated software PERVEL

Bus accidents involving rollover are rare but may lead to severe consequences. On the 15th November 2007, at late afternoon, a major accident involving a passenger car and an interurban bus occurred in a motorway in Portugal, resulting in 17 fatalities and 23 serious injuries. Public interest in this accident was magnified and social consequences were aggravated due to the fact that the bus was carrying a study tour of students from a senior university.Following a careful at scene data collection by enforcement agents, the Public Attorney-General decided to establish a multidisciplinary team in charge of reconstructing the accident, finding the manoeuvres involved and explain the contribution of road elements, vehicles and each driver in the mechanisms that produced both the accident and its injuries. This team involved participants from the BT-GNR, (the highway police), the Technical University of Lisbon (IDMEC-IST) and the Portuguese National Laboratory of Civil Engineering (LNEC).It was concluded that the accident started with the car loss of control, followed by its side collision twice with the bus (first with the rear axle, and secondly with the front axle); then, both vehicles ran-off-the-road to the right side of the carriageway, crossed the existing guardrail at the end of the paved shoulder and invaded the steep slope embankment; the car stopped at the bottom of the slope in the ditch. While travelling in the roadside; the bus overturned, resulting in its body failure and the projection of several passengers.Computational simulation tools such as PC-Crash were used to reconstruct the accident. Also Madymo is used to analyse the behaviour of the occupants and to evaluate the injuries of the unbelted passengers as compared with what would have happened if they were effectively restrained by two point belts. Also simulations with three point belts were carried out to evaluate the effect of this improved restraint system under rollover conditions.No serious offences by any driver were detected, as the car was travelling at 120 km/h (the bus at 90 km/h) and both vehicles were in their respective lanes. A definitive explanation for the car driver

Excessive speeds are a major contributing factor for road accidents. Research has shown that both accident risk and injury severity resulting from accidents vary with speed due to physical reasons and to psycho-physiological effects on road users; relations between these factors have been found at the individual and the system levels.Most road safety plans include speed management as a tool for mitigating road crash consequences and reaching the targeted safety levels. In that perspective the Portuguese Road Safety Plan is no exception, and an integrated set of safety interventions is programmed and being implemented, including legislation update, road infrastructure improvements, information campaigns, the use of ITS and enforcement activities.Automatic systems have been successfully used for enforcing compliance with speed limits in several countries, resulting in lower prevalence of excessive speeds and safety improvements in the vicinity of their installation sites. The investments for the implementation of these systems consistently show favourable benefit-cost ratios, provided the installation sites are carefully selected. In fact, automatic speed enforcement was identified as a road safety best practice in SUPREME, a 6th Framework European research project, in which best practices in road safety were collected, analysed and summarised. However, in some countries, social resistance to this type of devices may arise, if misunderstandings are allowed to develop about their main function.In this paper a presentation is made of the technical criteria being applied in Portugal for the selection of eligible sites for installation of automatic speed enforcement and for monitoring its safety effects. Also, a brief description is made of the related activity being taken within the Portuguese Road Safety Plan to ensure the needed social acceptability of this safety intervention.

Segundo as estatísticas nacionais, uma elevada percentagem de acidentes e vítimas ocorre em zonas urbanas: entre 2004 e 2006, 70% dos acidentes com vítimas e 44% das vítimas mortais ocorreu nestas áreas. As características das redes rodoviárias urbanas, nomeadamente o tipo de pavimento, constituem factores importantes nas condições de circulação dos veículos e consequentemente na ocorrência de acidentes. No âmbito do projecto “IRUMS – Infra-estruturas Rodoviárias Urbanas Mais Seguras”, realizado em parceria pelo Laboratório Nacional de Engenharia Civil e pelo Departamento de Engenharia Civil da Universidade de Coimbra, foi estruturada uma base de dados de acidentes associada a um sistema de informação geográfica. Esta associação permite uma análise conjunta dos potenciais factores com influência no nível de sinistralidade, entre os quais o tipo de pavimento rodoviário e os volumes de tráfego. Nesta comunicação apresenta-se o resultado da análise da distribuição de acidentes para a cidade de Lisboa bem como as estimativas de taxas de acidentes, considerando os volumes de tráfego como indicador de exposição, por tipo de pavimento.

The automobile characteristics in terms of the flexibility of practicable distances, comfort and time schedule autonomy have made it the most demanded mode of transportation. In face of the negative impacts associated with road transportation such as congestion, pollution and road accidents, the quantification of the regular and diversified use of the automobile has become a clear need of our society. The amount of travel in a road network, or in part of it, may be represented by the traffic volume (usually expressed in vehicle kilometres/miles of travel

This paper summarizes the results of the bibliographic study on accident predictionmodels applied to urban areas. Several types of models where analyzed, namely foraccidents involving pedestrians or cyclists, collisions between motorized vehicles, totalaccidents, non injury accidents, accidents with fatalities, injury accidents, night timeaccidents and accidents involving only vehicles. Models with different levels ofdisagregation were also studied: aggregated models describe general safety trends(national or regional); disaggregated models represent specific changes in thetransportation system.This study is part of the

According to official statistics, an important percentage of accidents and injuries are reported in Portuguese urban areas: from 2004 to 2007, 70% of the injury accidents and 43% of the fatalities occurred inside urban areas. To develop an efficient and affective strategy towards road safety, it is necessary that road administrations have the proper tools for the quantification of safety levels and the explicit consideration of safety issues in the road management process. The analysis of spatial accident distribution in road networks and the knowledge of the relations between accident frequencies and variables describing the urban road environment will allow a more efficient definition of priorities for intervention and safety funding. This can be achieved by means of accident prediction models adapted to the urban context where they are applied, and by the use of a Geographic Information System based methodology to analyse spatial patterns of road accidents. This paper summarizes the result of the bibliographic study on accident prediction models applied to urban areas and the data collection on road accidents, road infrastructure characteristics and traffic and land use information, integrated in a Geographic Information System, where it may be graphically visualized and analyzed.

The application of low-cost road and traffic engineering measures (LCEM) is a cost-effective method for reducing accidents and their consequences. Empirical evidence shows that enforcement contributes to improvements on driving behaviour and road safety; however, results from reducing enforcement are seldom presented.In this paper a presentation is made of the impact LCEM and changes in enforcement intensity had on selected driving behaviour variables and safety levels on a 170 km single carriageway trunk road. LCEM were implemented on the road, followed a year later by the commitment of exceptionally intense and severe law enforcement and, after two years, its relaxation. The impacts of these safety interventions were evaluated through observational before-after studies. The expected number of injury accidents was reduced by 41% (less 75% fatalities), when considering the combined effect of LCEM and enforcement; suppression of strict enforcement was related to a 20% increase in the number of fatalities.

Manual de boas práticas para uma mobilidade sustentável, no âmbito do projecto nacional "Mobilidade Sustentável" coordenado pela Agência portuguesa do Ambiente (Vol. II). O projecto Mobilidade Sustentável envolveu uma rede de 15 centros de investigação/universidades do país, incluindo o LNEC.

Nesta publicação apresentam-se os aspectos relativos à concepção do projecto Mobilidade Sustentável, principais conclusões e recomendações.

O tempo decorrido (ou a distância percorrida) até à ocorrência de um evento, ou a duração do mesmo, podem ser analisados através de modelos de duração baseados em risco (hazard-based duration models), os quais têm sido amplamente utilizados em campos como a medicina, as ciências sociais e a engenharia industrial. Contudo, são relativamente escassos os estudos que aplicaram modelos de duração à engenharia de transportes.Este capítulo inclui dois exemplos de aplicação de modelos de duração à investigação em engenharia de transportes. O primeiro diz respeito às distâncias percorridas por veículos descontrolados em despistes ocorridos na Carolina do Norte (E.U.A.). O segundo refere-se ao tempo decorrido até à transferência modal nas deslocações para a escola de um conjunto de alunos de 162 turmas de 51 escolas do ensino básico em Portugal.

Em Portugal, a investigação sobre o conhecimento dos fatores que afetam a probabilidade de ocorrência de acidentes tem-se centrado essencialmente nas estradas interurbanas. No entanto, as zonas urbanas, onde ocorrem elevadas percentagens de acidentes corporais requerem uma atenção prioritária. Com o presente estudo pretendeu contribuir-se para a melhoria da segurança rodoviária em meio urbano, através da criação de ferramentas que podem ser utilizadas em métodos de intervenção em que a segurança dos utentes vulneráveis seja considerada explicitamente nas fases de planeamento e gestão das redes viárias. Uma das referidas ferramentas resultou da elaboração de modelos de estimativa de frequência de acidentes para redes urbanas, segundo diversas desagregações, em função de características do elemento rodoviário: em intersecções (três ramos, quatro ramos e rotundas) e em segmentos; segundo o tipo de acidente (atropelamentos e restantes acidentes com vítimas); e segundo a inclusão de variáveis explicativas relacionadas com o ambiente rodoviário: simplificados (apenas com as variáveis de exposição) e globais (com todas as potenciais variáveis explicativas). O desenvolvimento destes modelos foi apoiado numa base de dados georreferenciada dos acidentes rodoviários ocorridos em Lisboa entre 2004 e 2007, com a qual foi possível explorar os dados de sinistralidade na área geográfica em análise. Estas ferramentas podem ser usadas diretamente na gestão das infraestruturas rodoviárias da cidade de Lisboa e, após pequenas adaptações, estendidas a outros municípios, dotando as respetivas entidades competentes em matéria de segurança rodoviária com informação rigorosa e detalhada sobre os fatores intervenientes na ocorrência de acidentes em meio urbano e a respetiva distribuição espacial.

Os dados discretos ou em escala nominal desempenham um papel fundamental nos transportes porque muitas análises de políticas lidam com estes tipos de dados. Exemplos de dados discretos nos transportes incluem o modo de transporte (automóvel, autocarro, comboio), o tipo ou categoria de veículo e o tipo de acidente rodoviário (despistes, colisões frontais, colisões traseiras, etc.). O conhecimento do efeito das diferentes intervenções de segurança rodoviária na redução da gravidade das lesões resultantes de acidentes rodoviários exige uma avaliação empírica detalhada das interações, reconhecidamente complexas, entre veículos, estrada e fatores humanos.Os avanços mais recentes nas metodologias estatísticas aplicadas a dados discretos sobre sinistralidade rodoviária permitiram o desenvolvimento de modelos sofisticados capazes de serem usados para determinar com rigor a influência dos fatores acima referidos nos níveis de gravidade das lesões resultantes dos acidentes rodoviários.Neste contexto, a aplicação de modelos de resultado discreto permite identificar um conjunto de fatores, relacionados com a envolvente rodoviária, que são estatisticamente relacionáveis com a gravidade das lesões dos utentes envolvidos em acidentes rodoviários, permitindo aperfeiçoar a conceção e o dimensionamento das estradas, bem como orientar políticas conducentes à melhoria da segurança rodoviária. Este capítulo inclui um exemplo de aplicação do modelo logit multinomial usando a gravidade das lesões no condutor como variável de resposta.

Spatial organization in cities has often given a special attention to the requirements of motorized vehicles, neglecting pedestrians and cyclists

The importance of sustainable urban mobility plans is widely recognized by local and regional authorities across Europe. Technological innovation opportunities such as those offered by current and future ICT can contribute for cities to advance towards sustainable mobility and accessibility for inclusive public spaces.This article is built on an innovative living lab experience of the Intermunicipal Community of the Algarve (AMAL), the regional transport authority, scientifically supported by the LNEC, in Portugal, that comprised the development of the designated

O conhecimento dos factores que afectam a probabilidade de ocorrência de um acidente éuma área de investigação relevante de há muitas décadas devido aos enormes custos para asociedade dos acidentes rodoviários. Em Portugal, os desenvolvimentos nesta matériacentraram-se essencialmente nas estradas inter-urbanas. No entanto, as zonas urbanas,caracterizadas por elevadas percentagens de acidentes corporais (cerca de 69% do total entre2004 e 2008), requerem uma atenção prioritária.Com o presente estudo pretendeu contribuir-se para a melhoria da segurança rodoviária emmeio urbano, através da criação de ferramentas que podem ser utilizadas em métodos deintervenção em que a segurança dos utentes vulneráveis seja considerada explicitamente nasfases de planeamento e gestão das redes viárias.A primeira ferramenta correspondeu à criação de uma base de dados georreferenciada dosacidentes rodoviários ocorridos na cidade de Lisboa entre 2004 e 2007, que permitiu adefinição de mapas digitais, com possibilidade de uma grande diversidade de consultas e decruzamentos de informação.A segunda ferramenta refere-se à elaboração de modelos de estimativa de frequência deacidentes para redes urbanas, segundo diversas desagregações: segundo o elementorodoviário: em intersecções (intersecção de três ramos, intersecção de quatro ramos erotundas) e em segmentos; segundo o tipo de acidente: atropelamentos e restantes acidentescom vítimas; e segundo a inclusão de variáveis explicativas relacionadas com o ambienterodoviário: simplificado (apenas com as variáveis de exposição) e global (com todas aspotenciais variáveis explicativas). Foi considerada a incorporação de dados de exposiçãorelativos aos utentes vulneráveis por forma a melhorar a capacidade de estimativa dasinistralidade em redes urbanas.Estas duas ferramentas podem ser usadas directamente na gestão de infra-estruturas, dotandoas entidades com competência em matéria de segurança rodoviária com informação rigorosa edetalhada sobre os factores intervenientes na ocorrência de acidentes em meio urbano erespectiva distribuição espacial.

No período de 1988 a 1993, ocorreram anualmente nas estradas rurais de uma faixa de rodagem e dois sentidos da Rede Rodoviária Nacional de Portugal, em média, cerca de 1471 acidentes corporais anuais em curva fora de cruzamentos. Estes acidentes constituem cerca de 33% dos acidentes corporais fora de cruzamentos participados na referida rede.O objectivo do presente trabalho é contribuir para o conhecimento da influência da estrada na ocorrência de acidentes e para o desenvolvimento de um método para avaliação de traçados rodoviários do ponto de vista da segurança.Foram realizadas in situ campanhas de recolha de dados sobre as distribuições de velocidades dos condutores, os quais foram relacionados com as características geométricas das estradas e com a respectiva sinistralidade. Foram desenvolvidos modelos para estimativa de perfis de velocidade de circulação livre, bem como modelos para estimativa da frequência de acidentes, em estradas de uma faixa de rodagem e dois sentidos, adaptados às condições de tráfego nacionais. Os referidos modelos foram integrados num procedimento para detectar inconsistências de velocidade em especial associadas à ocorrência de acidentes em curva, o qual foi usado para fundamentar uma proposta de quantificação de critérios de homogeneidade de traçado, adaptados à realidade do sistema de tráfego rodoviário português.

Safety performance indicators (SPIs) can be used to improve our understanding of the causes of accidents, and they can be used to monitor policy interventions. In that sense, they are one of the elements of a safety management system. SafetyNet Work Package 3 deals with these indicators. On the basis of the ETSC report 'Transport Safety Performance Indicators' (2001) [1], seven domains for SPIs have been defined: 1. Alcohol and drug-use 2. Speeds 3. Protection systems 4. Daytime running lights 5. Vehicles (passive safety) 6. Roads 7. Trauma management In Work Package 3, seven tasks are defined that work on each of the respective SPI domains. Their findings are communicated through reports, presentations, conferences and a website. This deliverable deals with the communication of findings through the European Road Safety Observatory website (http://www.erso.eu). The report contains those web texts, published on the website, that are adapted from the contents of Deliverable 3.1 from SafetyNet WP3, the State-of-the-art report. The web text focuses on the explanation of the concept of SPIs, and gives background details of two SPI areas: alcohol & drugs, and speeds. In the future new web texts related to the subject of Road Safety Performance Indicators will be added to the ERSO website.

This report compares the safety performance of 27 European countries

This document provides details about the theory behind the development of Safety Performance Indicators (SPIs) in seven major areas which are central to the fields of activity in road safety in Europe. The fields of activity were selected as a result of reviews of national road safety plans in many of the EU countries and around the world and are considered the central themes of activity in road safety, necessary to bring about a significant improvement in road safety in the EU countries. Within each field SPIs were developed which are directly related to that field of activity, can be quantitatively measured, can provide the basis for the assessment of the level of road safety in each country and can serve as an indicator to describe the level of activity in that field and country and can provide a yardstick for comparison. Comparisons can be before and after certain actions are taken or can be comparisons between countries. As stated above, this document deals with the theory behind the development of each of the seven SPIs. It provides the rationale behind their development, the proofs for their relevance in the specific fields and the existing limitations that led to the adoption of the specific SPIs. The document provides also some recommendations for the possible improvements required to obtain better SPIs. Two companion documents are also being prepared. One is a manual which provides details on the procedures necessary to collects the required data for the development of each SPI in each country. The second document provides results on the data collected so far for each of the 25 EU countries and the SPIs developed so far, based on the data submitted by each of the countries. It can be seen that a lot of work still has to be done, both in collecting the necessary data and in improving the SPIs, once better and more detailed data becomes available.

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 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.

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: -

The present document describes prediction models for accident, fatalities,serious injuries and killed and seriously injured victims, adjusted to bidirectionaldata of Portuguese motorway sections. The study was developed at LaboratórioNacional de Engenharia Civil (LNEC) in the scope of Workpackage 2 - SafetyImpact Assessment and Accident Prediction Model of the RIPCORD-ISERESTproject, carried out under the 6th European Framework Program. It covers theissues related to modeling accidents using the Negative Binomial modelregressions as well as detailed diagnostic checks of the models obtained.The data used were collected over a five year period, ranging from 1999 to2003. Several explanatory variables were measured concerning exposure,number of lanes, presence of an additional lane, lane widths, type and widths ofthe road

The main objective of the project was the benchmarking of road safety performances and developments of ten Latin American countries.The comparison allowed to identify the similarities and differences between countries, not only on the number of crashes and casualties, but also on the factors, circumstances and events that influence the risk of a crash and the severity of its outcome. The analysis was performed in the following areas

The research reported in this paper is part of the R&D project COST-TRENDs, funded by the Portuguese Foundation for Science and Technology. It presents a strategic assessment study of the hinterland connections centred in the Port of Sines, in Portugal, that integrates the core network corridor of the Trans-European Transport Network (TEN-T) designated as the Atlantic corridor. The study comprised the analysis of trends of maritime freight costs until 2020 and the assessment of alternative intermodal freight transport options to reduce costs along the multimodal transport chains. The options evaluated focused in the Iberian section of the Atlantic corridor and included the combination of maritime-short sea shipping, maritime-rail, maritime-road and, also, rail-air modes. The study estimated several key performance indicators for each option which aim to provide useful inputs to transport policy.

The literature shows that the development of the railway system in most European countries had a key role both in the evolution of urban systems and regional dynamics. On the other hand, it can be said that railway stations might act as important drivers for promoting sustainable land-use changes, namely of node and place functions which can be consistently balanced.The future Portuguese High-Speed Railway (HSR) network is considered as a major strategic transport scheme at both the Iberian and national levels. Its first stage comprises three routes. Of these, one links the Lisbon Metropolitan Area with the Spanish border of Badajoz, being an integral part of the HSR between both Iberian capitals, whereas the other two form the Atlantic Axis, encompassing a system of cities ranging from Lisbon to Porto, an from the latter point to Braga, Vigo and Coruña, concentrating nearly 80% of the whole Portuguese population, and serving an area generating about 90% of Portugal
