The aircraft is a means of transportation that operates mainly in the air; however, it starts and ends its journey on the ground. Due to the aircraft’s structural complexity, simulation tools are used to understand and to predict its behavior in its movements on the ground. Simulation tools allow adjusting the observation parameters to gather a greater amount of data than real tests and explore interactions of the aircraft and their individual components with external objects such as pavement imperfections. This review aims to collect information on how to simulate the aircraft interaction with traffic-dependent energy harvesting systems. The specifications and framework to be met by a conceptual design are explored. The different configurations for simulating the aircraft configuration result in the selection of the two-mass-spring-damper model. For the components, especially the landing gear, a deployable element for on-ground movements, several existing models capable of translating the tire are also presented, resulting in a selection of point-contact, Fiala and Unified semi-empirical models. It is verified which software can address the proposed simulation, such as GearSim from SDI-Engineering and Matlab/Simulink/Simscape Multibody from MathWorks.

Society is dependent on transport systems, not only to meet its daily needs with short journeys but also to meet their arising needs with longer distances. The ability to connect remote regions and the trip duration makes the aircraft a mode of transport for distant travel. However, it impacts greenhouse gas production. The survey for new ways to reduce greenhouse gas emissions emerges from the contribution of energy harvesting systems. Energy harvesting technology has been presenting prosperous solutions and applications in road pavements. Due to the similarity between road pavements, this paper addresses state-of-the-art technologies for airport pavements and road pavements, aiming to analyze which ones can be developed for application in airport pavements. An analysis is presented not only for the density, efficiency, and energy generation, but also for each energy harvesting technology’s implementation and technology readiness level. The photovoltaic technology, to be incorporated into airport pavements, will allow sustainable energy generation dependent on the airport location. The hydraulic/pneumatic technology, to be incorporated into the airport pavements, will generate electrical energy based on aircraft movement.

Road transportation has always been inherent in developing societies, impacting between 10–20% of Gross Domestic Product (GDP). It is responsible for personal mobility (access to services, goods, and leisure), and that is why world economies rely upon the efficient and safe functioning of transportation facilities. Road maintenance is vital since the need for maintenance increases as road infrastructure ages and is based on sustainability, meaning that spending money now saves much more in the future. Furthermore, road maintenance plays a significant role in road safety. However, pavement management is a challenging task because available budgets are limited. Road agencies need to set programming plans for the short term and the long term to select and schedule maintenance and rehabilitation operations. Pavement performance prediction models (PPPMs) are a crucial element in pavement management systems (PMSs), providing the prediction of distresses and, therefore, allowing active and efficient management. This work aims to review the modeling techniques that are commonly used in the development of these models. The pavement deterioration process is stochastic by nature. It requires complex deterministic or probabilistic modeling techniques, which will be presented here, as well as the advantages and disadvantages of each of them. Finally, conclusions will be drawn, and some guidelines to support the development of PPPMs will be proposed.

This study analyzes the relationship between the spread of the SARS-CoV-2 virus (COVID-19) and the mobility patterns of the Portuguese population. By reducing mobility, the idea is that contacts are reduced, countering the spread of the virus in the community. As an indicator of the spread of the virus, the reproduction number (Rt) was used. Data from Google's Community Mobility Reports was used to evaluate changes in mobility patterns. This report uses location data from Android mobile phone users. The locations are divided into retail and recreation, grocery and pharmacy, parks, transit stations, workplaces and residential. In this year of the COVID-19 crisis in Portugal, population mobility patterns have changed over the various phases of the pandemic. At first, all mobility was affected uniformly, with the population avoiding much of the activity outside the home. In a second phase, there was some adaptation, and the areas considered to be of lower risk had less impact, emphasizing the changes in the relationship between daily life and the workplace.

SARS-CoV-2 emerged in late 2019. Since then, it has spread to several countries, becoming classified as a pandemic. So far, there is no definitive treatment or vaccine, so the best solution is to prevent transmission between individuals through social distancing. However, it is not easy to measure the effectiveness of these distance measures. Therefore, this study uses data from Google COVID-19 Community Mobility Reports to understand the Portuguese population’s mobility patterns during the COVID-19 pandemic. In this study, the Rt value was modeled for Portugal. In addition, the changepoint was calculated for the population mobility patterns. Thus, the mobility pattern change was used to understand the impact of social distance measures on the dissemination of COVID-19. As a result, it can be stated that the initial Rt value in Portugal was very close to 3, falling to values close to 1 after 25 days. Social isolation measures were adopted quickly. Furthermore, it was observed that public transport was avoided during the pandemic. Finally, until the emergence of a vaccine or an effective treatment, this is the new normal, and it must be understood that new patterns of mobility, social interaction, and hygiene must be adapted to this reality.

In recent years, civil aviation has experienced intense growth. To meet this demand, a new generation of aircrafts has been developed, with more complex landing gear configurations and higher total gross weight. Therefore, new challenges were created for the design of airport pavements. In this sense, software tools were created to meet this need. So the focus of this paper is to understand how this computational capacity has been applied in the design of airport pavements. To do this, this writing addresses the evolution of design methods, their formulations, how these methods are applied, and finally, what is the state-of-the-art for the software tools for airport pavement design. For the development of this text, the software FAARFIELD (USA), Alize-Airfield (France), APSDS (Australia), and PCASE (USA) were evaluated. Finally, it was concluded that the main airport pavement design software has similar formulations and methodologies. In general, these applications apply layered elastic methods, with little variations and adaptations to the different existing normative standards. Also, some applications apply finite element methods to their design steps.

Worldwide, more than 1.25 million people die annually in road traffic accidents and between 20 and 50 million more are injured. By 2030, highway-related crashes are projected to be the 5th leading cause of death in the world. Road accidents have several contributing factors, including roadway conditions, vehicle conditions, and factors related to the road users. While some of these factors have been studied extensively by researchers very few focused on quantifying the relationship between accidents frequency and pavement quality. Before 1990s, due to the lack of pavement data collection technology, it was very difficult to carry out state-wide scale studies relating pavement quality and road safety. However, in the past decades, there has been a huge growth and awareness in the importance of road safety, leading to a significant increase of research in the topic. Researchers started to study other contributing factors to accidents occurrence and due to the development of high-speed friction measurement tools, agencies can now include friction into network level Pavement Management Systems (PMSs). The objective of this article is to contribute to the incorporation of safety concerns into Pavement Management by performing an exploratory analysis to assess the impact in the agency, user and total costs of performing two different maintenance policies. The methodology consisted in evaluating the evolution of the condition of the road pavements using pavement performance prediction models, followed by the prediction of the expected number of accidents and, finally the calculation of the agency and user costs. The results obtained provided a strong starting point to understand the requirements to solve this type of problems that not only affect road agencies but also the society in general.

This paper presents the results of a laboratory study performed on unpaved roads. Both unreinforced wearing layers and layers reinforced with geosynthetics were considered for their construction and study, as geosynthetics are reported to improve the behavior of the granular layers. Reinforcement was introduced by means of a polyester geogrid. Four different types of soils were considered in the study, each one with different percentages of sand, silt and clay. The soil layers were placed, compacted and tested with the optimum water content. Traditional soil characterization was performed, which included particle size analysis, density of solid particles, consistency limits, compaction and California Bearing Ratio. Wheel Tracking tests were performed to study the unpaved road behavior in the different conditions. In the majority of the tests, a compressive material was used beneath the soil layer, to simulate the existence of a weak and deformable subgrade. The results of the study conducted to the following main conclusions: soil D, the one with the highest percentage of fines, shows the best performance under the Wheel Tracking test, for all conditions under study; soil A, the coarsest soil, performed worst; soils B and C improve their performance significantly when the geogrid reinforcement was included.

This paper presents a new pavement energy harvest system that was developed in Portugal by the Waydip Company in collaboration with the Pavement Mechanics Laboratory of the University of Coimbra. After carrying out testing in the laboratory on one Waynergy People prototype module, 25 Waynergy People modules were set up in the entrance to a shopping centre in Lisbon, Portugal. The electrical energy generated by the Waynergy People pilot plant was 15,525.0 J or 4.31 Wh. This energy was harvested from 2,070 people walking over the system, with each person averaging 5 steps, which means that the average energy generated per step was 1.50 J on each module. We recorded a peak value of 4.20 J, which is equal to the energy produced by a person weighing 100 kg jumping. The maximum energy generated during one day was 126,540.0 J, or 35.2 Wh, and the average energy generated per day over the four months of the Waynergy People pilot was 90,417.0 J or 25.1 Wh.

In the period 1975–1985 several new railway infrastructures were built in Brazil. After this period the construction of new railways stopped. With the new railway concessions in 1996, minor maintenance work was undertaken on the old railway infrastructures and only in the last six years have new railway infrastructures begun to be constructed. In São Paulo, between 1978 and 1985, some old railways infrastructures were also rebuilt using sub-ballast or platform with granular soils in the track layers. This paper presents a comparative analysis between two sub-ballast specifications, one used in the 1975–1985 period and another used nowadays for new railway constructions in Brazil. The main sub-ballast functions were identified, including the bearing capacity and the hydraulic conductivity. To assess the sub-ballast in terms of these technical criteria, samples were collected from two railways built more than 30 years ago, one on sandy soil and the other on stony fine aggregates. Samples of the typical fine silty soil of UNICAMP campus were also collected to evaluate the possibility of using the two types of sub-ballast on this type of soil. The samples collected in the field were tested in laboratory for evaluation of particle size, load capacity and hydraulic conductivity. Finally, the performance of each of the two granular mixtures used as sub-ballast layer in Brazilian railway infrastructures was analysed.

Research into energy harvesting technologies has increased considerably in recent years. The particular case of energy harvesting on road pavements is a very recent area of research, with different technologies having been developed for this purpose. However, none of them has presented high conversion-efficiency rates nor technical or economic viability. Looking at other renewable energy technologies, the inclusion of not only electrical but also, in some cases, mechanical energy-storage units has led to an increase in global efficiency and, consequently, viability. This paper deals with the technical study of the integration of a mechanical energy-storage system in a road pavement hydraulic energy-harvesting device, in order to evaluate the impact on global efficiency. The main goal is to quantify the efficiency of the energy storage as well as the overall efficiency of the system, including the harvesting, transmission and conversion-efficiency rate, comparing it to scenarios where no storage system is used. Finally, the conclusions on the performance of each system are presented.

Addressing the multidimensional challenges involved in advancing the sustainability of pavement systems requires the development of optimisation-based decision support system (DSS) for pavement management with the capability to identify optimally sustainable pavement maintenance and rehabilitations (M&R) strategies. The main objective of this research work is to develop a multi-objective optimisation framework that hosts a comprehensive and integrated pavement life cycle costs–life cycle assessment model that covers the pavement’s whole life cycle, from the extraction and production of materials to construction and maintenance, transportation of materials, work-zone traffic management, usage and end-of-life. The capability of the proposed DSS is analysed in a case study aiming at investigating, from a full life cycle perspective, the extent to which a number of pavement engineering solutions are efficient in improving the environmental and economic aspects of pavement sustainability, when applied in the management of a road pavement section. Multiple bi-objective optimisation analyses considering accordingly agency costs, user costs and greenhouse gas emissions were conducted based on a multi-objective genetic algorithm. Pareto fronts were obtained for each analysis, originating a set of non-dominated maintenance and rehabilitation solutions. Posteriorly, a multi-criteria decision analysis method was used to find the best compromise solution for pavement management.

Current practice adopted by highway agencies with regards to pavement management, has mostly consisted of employing life cycle costs analysis (LCCA) systems to evaluate the overall long-term economic efficiency of competing pavement design and maintenance and rehabilitation (M&R) activities alternatives. This way of supporting the decision-making process as it relates to pavement management, in which little or no importance is given to environmental considerations, suggests the need for pavement management decision-support systems (DSS), which, by integrating multi-disciplinary and complementary pavement life cycle modelling approaches, enable the decision makers (DMs) to properly account for, consider and assess the lifetime impacts of their decisions and practices regarding sustainability goals and targets. This only can be achieved by employing techniques and tools provided with a comprehensive and wide-scoped cradle-to-grave capacity of analysis. To address this multifaceted problem, this paper presents a comprehensive and modular multi-objective optimization (MOO)-based pavement management DSS which comprises three main components: (1) a MOO module; (2) a comprehensive and integrated pavement life cycle costs - life cycle assessment (LCC-LCA) module that covers the whole life cycle of the pavement; and (3) a decision-support module. The potential of the proposed DSS is illustrated with one case study consisting of determining the optimal M&R strategy for a one-way flexible pavement section of a typical Interstate highway in Virginia, USA, which yields the best trade-off between the following three often conflicting objectives: (1) minimization of the present value (PV) of the total life cycle highway agency costs (LCHAC); (2) minimization of the PV of the life cycle road user costs (LCRUC); and (3) minimization of the life cycle greenhouse gas emissions (LCGHG). In comparison to the traditional maintenance strategy, the proposed DSS suggest a maintenance plan that reduces LCHAC by 15%, LCRUC by 28% and LCGHG by 26%

Purpose This paper aims to deal with the development of a software tool to simulate and study vehicle – road interaction (VRI) to quantify the forces induced and energy released from vehicles to the road pavement, in different vehicle motion scenarios, and the energy absorbed by the road surface, speed reducers or a specific energy harvester surface or device. The software tool also enables users to quantify the energetic efficiency of the process. Design/methodology/approach Existing software tools were analysed and its limitations were identified in terms of performing energetic analysis on the interaction between the vehicle and the road pavement elements, such as speed reducers or energy harvest devices. The software tool presented in this paper intends to overcome those limitations and precisely quantify the energy transfer. Findings Different vehicle models and VRI models were evaluated, allowing to conclude about each model precision: bicycle car model has a 60 per cent higher precision when compared with quarter-car model, and contact patch analysis model has a 67 per cent higher precision than single force analysis model. Also, a technical study was performed for different equipment surface shapes and displacements, concluding that these variables have a great influence on the energy released by the vehicle and on the energy harvested by the equipment surface. Originality/value The developed software tool allows to study VRI with a higher precision than existing tools, especially when energetic analyses are performed and when speed reduction or energy harvesting devices are applied on the pavement.
