Vehicle trajectory descriptions are required for the development of driving behaviour models and in the calibration of several traffic simulation applications. In recent years, the progress in aerial sensing technologies and image processing algorithms allowed for easier collection of such detailed traffic datasets and multiple-object tracking based on constrained flow optimization has been shown to produce very satisfactory results, even in high density traffic situations. This method uses individual image features collected for each candidate vehicle as criteria in the optimization process. When dealing with poor image quality or low ground sampling distances, feature-based optimization may produce unreal trajectories.In this paper we extend the application of the k-shortest paths algorithm for multiple-object tracking to the motion-based optimization. A graph of possible connections between successive candidate positions was built using a first level criteria based on speeds. Dual graphs were built to account for acceleration-based and acceleration variation-based criteria. With this framework both longitudinal and lateral motion-based criteria are contemplated in the optimization process. The k-shortest disjoints paths algorithm was then used to determine the optimal set of trajectories (paths) on the constructed graph.The proposed algorithm was successfully applied to a vehicle positions dataset, collected through aerial remote sensing on a Portuguese suburban motorway. Besides the importance of a new trajectory dataset that will allow for the estimation of new behavioural models and the validation of existing ones, the motion-based multiple-vehicle tracking algorithm allowed for a fast and effective processing using a simple optimization formulation.

The objective of this paper is the analysis of the state-of-the-art in risk indicators and exposure data for safety performance assessment in Europe, in terms of data availability, collection methodologies and use. More specifically, the concepts of exposure and risk are explored, as well as the theoretical properties of various exposure measures used in road safety research (e.g. vehicle- and person-kilometres of travel, vehicle fleet, road length, driver population, time spent in traffic, etc.). Moreover, the existing methods for collecting disaggregate exposure data for risk estimates at national level are presented and assessed, including survey methods (e.g. travel surveys, traffic counts) and databases (e.g. national registers). A detailed analysis of the availability and quality of existing risk exposure data is also carried out. More specifically, the results of a questionnaire survey in the European countries are presented, with detailed information on exposure measures available, their possible disaggregations (i.e. variables and values), their conformity to standard definitions and the characteristics of their national collection methods. Finally, the potential of international risk comparisons is investigated, mainly through the International Data Files with exposure data (e.g. Eurostat, IRTAD, ECMT, UNECE, IRF, etc.). The results of this review confirm that comparing risk rates at international level may be a complex task, as the availability and quality of exposure estimates in European countries varies significantly. The lack of a common framework for the collection and exploitation of exposure data limits significantly the comparability of the national data. On the other hand, the International Data Files containing exposure data provide useful statistics and estimates in a systematic way and are currently the only sources allowing international comparisons of road safety performance under certain conditions.

Road restraint systems are roadside structures that include safety barriers, crash cushions, terminal of barriers, the transitions among different road restraint systems, motorcyclist protection devices, etc. These systems are used to protect vehicle occupants from dangerous roadside elements and are a key issue in roadside safety.In Europe, safety barriers are currently designed for different performance levels using three main criteria: containment, impact severity and deformation of the barrier.The impact severity level is exclusively associated with injury risk to vehicle occupants and assumes that different severity levels correspond to different levels of injuries.From these observations, three questions emerge: what consequences can be expected for the passengers of an errant vehicle when it is contained by a safety barrier? Systems with different impact severity levels lead to diverse severity consequences? What are the benefits of using barriers with lower impact severity levels?To answer these questions this paper examines how the number of run-off-the-road crashes and victims

The economic appraisal of the external effects of transport options can provide important data for policy making. On the other hand, impacts of non-motorized modes have often been undervalued in comparison to other transport modes. To this end, assessing the potential health benefits of walking and cycling is being increasingly recognized as an important step to promote sustainable mobility policies.This paper is built upon the contracted study for the World Health Organization (WHO) on the economic appraisal of health benefits of walking and cycling investments for the City of Viana do Castelo. This Portuguese city which integrates the WHO European Healthy Cities Network provided a suitable policy context for the former application in Portugal of the WHO Health Economic Assessment Model (HEAT) for appraising the health benefits of non-motorized transport. The study comprised the evaluation of the following investment actions: a) Improvements of the urban public space for pedestrians; b) Planning future cycling infrastructures. This paper provides a discussion of the methodological challenges and key findings that have arisen from the WHO HEAT application study, when trying to answer the following questions:- If x people cycle (or walk) a distance of y kilometers on most days, what is the economic value of the correspondent health benefits? - What levels of uptake of cycling in the future are required for the cycling plan to be economic viable? - What health benefits are associated to a projected increase in the traffic levels of pedestrians (% increase from the reference level)? - Do health benefits of cycling (and walking) investments outweigh their costs?Results from this study make it able to add novel evidence for the Portuguese urban context on the potential health benefits of walking and cycling (maximum and mean annual health benefits), including the cost-benefit ratio indicators. These indicators are expected to be useful for policy makers and city officers involved in the promotion of sustainable mobility.

This paper summarizes the result of a study regarding the creation of tools that can be used in intervention methods in the planning and management of urban road networks in Portugal. The first tool relates the creation of a geocoded database of road accidents occurred in Lisbon between 2004 and 2007, which allowed the definition of digital maps, with the possibility of a wide range of consultations and crossing of information.The second tool concerns the development of models to estimate the frequency of accidents on urban networks, according to different desegregations: road element (intersections and segments); type of accident (accidents with and without pedestrians); and inclusion of explanatory variables related to the road environment. Several methods were used to assess the goodness of fit of the developed models, allowing more robust conclusions.This work aims to contribute to the scientific knowledge of accidents phenomenon in Portugal, with detailed and accurate information on the factors affecting its occurrence. This allows to explicitly include safety aspects in planning and road management tasks.

Mobility has an important impact on the overall functioning of cities and quality of life of citizens. On the other hand, motorized road traffic is associated with high levels of noise and air pollutant emissions along with congestion and other externalities, leading to considerable social and environmental costs and degradation of human health. Following the World Health Organization, physical inactivity is one of the leading risks in Europe, associated with nearly 1 million deaths per year. In Portugal around 69% of the adult population do not reach the minimum recommended level of physical activity and 31% were considered sufficiently and highly active. Therefore, more sustainable transport modes such as walking and cycling are envisaged. This paper is built upon the contracted work with the city of Viana do Castelo, located in the North of Portugal, conducted for the World Health Organization (WHO) by the University of Minho and LNEC. The work integrates a research roadmap (case study plan for the application of the Health Economic Assessment Tool) for the appraisal of health benefits of specific walking and cycling investments in the city. The work presented here focus on the former part of the study which involved joint team work with the city officers for defining the target policy scenarios for using the WHO Economic Assessment Tool, the exchange of experiences and practices with other European cities regarding the use of this tool for health benefits assessment, the characterization of the mobility patterns at the reference and alternative policy scenarios set for the cost-benefit analysis, the data collection plan and the expected impacts from the early consideration of health benefits of those non-motorized investments. Results from the evaluation study can help the City elected officials to demonstrate the health benefits of walking and cycling investments. Individuals

According to official statistics, a large percentage of crashes in Portugal are reported on urban roads. For instance, from 2004 to 2007, about 70% of all injury accidents and 43% of the fatalities occurred inside urban agglomerations. This important safety problem has also been observed on the urban network of Lisbon. Understanding this significant problem, the Government of the Portuguese Republic via its research grant agency

Single carriageway multilane roads are not, in general, a very safe type of road, mainly because of the high number of seriously injured victims in head-on collisions, when compared with dual carriageway multilane roads, with a median barrier.In this paper the results of a study on the effect of the application of several low cost engineering measures, aimed at road infrastructure correction and road safety improvement on a multilane road EN6), are presented. The study was developed by the National Laboratory of Civil Engineering (LNEC) for the Portuguese Road Administration and involved a comparison of selected aspects of motorized trafficbehaviour (traffic volumes and speeds) measured in several sections of EN6, as well as monitoring of road safety developments in the same road. The applied low cost engineering measures allowed a reductionof 10% in the expected annual number of personal injury accidents and a 70% decrease in the expected annual number of head-on collisions; the expected annual frequency of accidents involving killed and seriously injured persons was reduced by 26%.

This paper is built on an innovative experience of the Intermunicipal Community of the Algarve Region (Regional Transport Authority), scientifically supported by the LNEC in Portugal, that comprised the development of the designated "Action Plans for Sustainable Mobility" (PAMUS) for the region, a network of sixteen cities. Following the Regional Operation Program, these plans were "to support the transition for a low carbon economy in all sectors" and, also, the investment priority "Promotion of low carbon in all the territory, namely urban areas, including the promotion of sustainable and multimodal urban mobility, adaptation and mitigation measures" (of energy consumption and CO2 emissions). The development of the PAMUS in the Algarve region comprised several interconnected components: an integrated approach for the development of plans that included a collaborative platform of stakeholders, a communication strategy to the public and a technological component to be used by the people (app VAMUS) and the acquiistion of cycling data for the region (STRAVA interface). In July 2016, the sixteen Mayors of the region signed a letter of commitment and agreed to work together towards sustainable mobility goals. This collective action represented a disruptive governance step aiming to trigger a positive behaviour change towards low carbon transport where cycling and walking have a role. The novel features of the successful experience of the PAMUS developed in the Algarve region will be presented and discussed considering other international planning experiences in Europe (e.g. France) and beyond Europe (e.g. Brazil).

Greater cooperation across transport modes in research and development activities has the potential to develop systems thinking, optimise use of resources and improve services for customers. This paper presents the findings of a Horizon 2020 project called Users, Safety, Security and Energy in Transport Infrastructure (USE-iT) which aimed to encourage greater cross-modal collaboration, through the identification of common challenges and development of a cross-modal research roadmap to address these. USE-iT and its sister project FOX identified more than 300 technologies, processes and systems that could benefit from a cross-modal approach. The involvement of industry was an integral part of this process, and a key objective of the project was to bring together stakeholders from all modes to facilitate knowledge transfer and develop a network for future cooperation. The paper focuses on research supporting the reduction of energy consumption and carbon emissions across transport modes, which was one of four topic areas addressed by USE-iT.

Descrevem-se os impactes da sobrecarga dos veículos pesados (peso bruto e carga por eixo) na durabilidade da infraestrutura (pavimentos e obras de arte), na operação das rodovias (capacidade, níveis de serviço e segurança rodoviária), na economia (custos do transporte), bem como no ambiente (emissões aéreas).

Transport plays a crucial role in urban development by providing access for people to education, markets, employment, recreation, health care and other key services. Cities which prioritize public transport and non-motorized modes are considered at the top of surveys measuring urban quality of life. Concerns over the quality of life have spread to the growing use of active transportation modes, and as so, proximity to the public transportation system is highly valued. The relationship between public transport accessibility and residential land value is the subject of many recent researches. A house located near public transports will tend to be sold at higher prices. This is due to the convenience that public transportation brings to its influence area, enabling quick access to the network and reduced travel times. However, some studies have found that this proximity can induce adverse effects on property values. The main concern of this paper is to address the importance of a public transport subway system in urban areas, and to analyse the effect of housing distance to stations has in real estate prices. A geocoded database integrated in a geographical information system was used, containing information on housing unit

Benchmarking can be defined as a systematic process of searching for best practices, innovative ideas and highly effective operating procedures that lead to superior performance. In this sense, benchmarking is the first step to learn from the results obtained by others "in the same class."This paper presents the results from a research project with the aim of developing a methodology to assess road safety performances in ten Latin American countries and benchmark their performance against a set of indicators and best practices leading to a set of recommendations for individual countries and for other stakeholders to further improve road safety. The methodological approach was based on the road safety target hierarchy used in the SUNflower project, which requires a clear understanding of traffic safety processes at different levels in the hierarchy, as well as the causes and consequences that lead to casualties and costs for society.The participating countries were Argentina, Brazil, Chile, Colombia, Costa Rica, Cuba, Ecuador, Mexico, Paraguay and Uruguay. The comparisons between them allowed to identify the similarities and differences, not only on the number of crashes and casualties, but also on the factors, circumstances and events that influence the risk of crashes and the severity of their outcome. Several aspects were deeply analysed, namely road safety strategies, including key interventions and main stakeholders, the main characteristics of the road transport system, and the trends in fatal injuries and crashes. A special focus was given to the following subjects: pedestrians, powered two-wheelers, drink and driving, speed, seat belts and child restraint use, road infrastructure and trauma management.

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.

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.

According to the Global Status Report on Road Safety 2018 (WHO, 2018b), the number of road traffic injuries claimed 1.35 million lives in 2016. Based on the WHO regions, road traffic fatality rates are increasing in the African region from 26.1 fatalities per 100,000 inhabitants in 2013 to 26.6 fatalities per 100,000 inhabitants in 2016. Therefore, the African region is the worst performing WHO region. Over the same period, there was an improvement in road fatality rates in the WHO Europe region. Road traffic injury in Africa is even expected to worsen further, with an increasing of 55% in road traffic fatalities over the period from 2016 until 2030 (WHO, 2018c).SaferAfrica project aims at establishing a Dialogue Platform between Africa and Europe focused on road safety and traffic management issues.

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
