A utilização de machine learning tem despertado a curiosidade e o interesse do meio académico e empresarial. Com efeito, a aplicação de machine learning, baseada em técnicas capazes de aprender com os dados, tem sido efetuada com sucesso em diversos contextos. Este sucesso é particularmente evidente nas áreas que utilizam grandes volumes de dados e que procuram obter informação que permita alimentar modelos de previsão.Na área dos Transportes, para além da resolução de questões relacionadas com a mobilidade, é expectável que a aplicação de técnicas de machine learning venha a ser cada vez mais frequente em questões relacionadas com a gestão de infraestruturas, em particular no estabelecimento de modelos de previsão do comportamento.Neste capítulo procura-se evidenciar o potencial da aplicação de machine learning em sistemas de gestão de pavimentos, através da descrição de alguns dos trabalhos desenvolvidos pelos autores neste domínio, essencialmente relacionados com a aplicação de machine learning no desenvolvimento de modelos de previsão do desempenho dos pavimentos, uma das temáticas essenciais dos sistemas de gestão de pavimentos.

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

Transport infrastructures such as roads, railways and runways are under increased traffic loading and their rehabilitation has to be performed in an efficient way, structurally and financially. In this process, monitoring of structural and functional capacity of transport infrastructures using non-destructive tests is performed in a systematic way. It is important to take the advantages of these measurements in order to plan a future rehabilitation. In this paper, four case studies of Building Information Modelling applied to transport infrastructures are presented. In case of road and airport pavements, the integration of structural capacity in the modelling was studied. Regarding the railways, a construction of a transition zone was addressed, as well as its behaviour during the first three years after entering in service. For both roads and railways, rehabilitation of existing infrastructures was modelled using BIM. In this way, it is possible to obtain a model that has information regarding the structural condition resulting from the continuous inspections. The BIM, being a relatively recent and innovative methodology, it is an important tool, with great potential when applied to transport infrastructures study. The main troubleshooting and consideration reached so far are presented herein, identifying the advantages of this approach.

The Architecture, Engineering, Construction, and Operations (AECO) sector has innovated in the design and construction methods using new technologies, with emphasis on the Building Information Modeling (BIM) methodology. However, it is still necessary to explore how this methodology can be applied to rehabilitation, in general, and to functional rehabilitation. BIM has as its main advantage, the possibility of an accurate representation of the geometry of the elements, integrating the information in several dimensions. The use of digital models is very important, since it allows optimizing the visualization and detail of these elements and their constructive processes, being a collaborative methodology. The present work intends to frame the BIM theme in the building

The rehabilitation of buildings has been growing in the last few years, being one of the areas with greater investment by the public and private sectors. The challenge on the rehabilitation of buildings allows reducing the use of resources, trying to reduce the environmental impact and making the construction sector more efficient. The energy rehabilitation of buildings is an important aspect of building rehabilitation, assuming particular importance among this type of interventions, trying to integrate economical and rational measures. The adoption of BIM methodology is associated with project planning, cost or energy analysis of the construction and project deliveries of the building and constructed structures; as a result, nowadays there is a greater demand to adapt these tools in the early stages of existing building lifecycle. The emergence of BIM software that can combine the modeling with the energy assessments allows the designer to make more conscious, accurate and informed decisions about the projects under development. The main objective of the research study developed is to understand how the use of digital tools allows a more efficient approach in the energetic rehabilitation of a building. In this way, and considering different rehabilitation solutions, it is possible to perform an analysis of alternatives, comparing them with the base solution and thus being able to understand which are the energetic gains, as well as the optimal solution. The results will be presented making possible their comparison with real measurements and the standards reference parameters for thermal performance. The possibility of editing the thermal properties of the building materials considered allows the realization of various simulations with several combinations of possible improvements. The results obtained can be an integrant part of a cost

This chapter explores the potential of co-creation for the planning of public open spaces that could be more attentive to different, unequal and diverse social ideas, needs and desires. Co-creation is discussed as an innovative opportunity for learning and (re)thinking urban planning. Exploring ideas, literature and experiences (from the European Project C3Places), the chapter discusses the role of co-creation for involving citizens in placemaking. This reflection addresses co-creation as a collective, contextual and engaged process of learning. From this perspective, co-creation is discussed as an open process of learning about predictable ideas in the relationship between socio-spatial imaginary, requirements, needs and urban design procedures from a transformative perspective.

The use of Building Information Modelling (BIM) is growing in the Architecture, Engineering, Construction and Operation (AECO) sector. BIM is an innovative methodology that enables a new approach to construction information management, based on the design of a virtual information model, and which presupposes a new paradigm in the way information exchange processes are treated among the various stakeholders throughout the asset

Public open space is a subject that belongs to us all. Every time we leave our homes, our private territory, we enter a space we have to share with others. Public space is the place for social interactions, strengthening sociability and ultimately exercising democracy. As a subject of study, public space has also long been analysed, explored and researched in various ways and under different guises, by planners, landscape architects and designers, anthropologists, social and cultural geographers, and urban historians. They all bring evidence on the role of public space in urban life, in the quality of urban environment and in the construction of cultural identity. Consequently, public space should deserve serious consideration by all - starting with those in charge and who hold regulatory responsibilities for those who use the places and ultimately give them life. As the UN-Habitat (2015) rightly recognises, a public space represents a key resource for social cohesion, economic development, and in particular liveability in urban settings. Public space is a resource that critically affects community values and positively impacts the quality of urban life. Backed by these premises, this book is about the co-creation of public open spaces, an issue at the core of the C3Places Project. To better understand the process, particularly the values of engaging people in the production of public space, is one of the C3Places’ objectives. The project is developing strategies and tools to help increase the quality and responsiveness of public spaces. In this process, the Project also aims to better understand how Information and Communication Technologies (ICTs) can influence co-creation and social cohesion. The chapters of this book bring science a little closer to the knowledge about the design, production and management of public spaces. 37 authors responded to the Project’s call to share experiences, visions and reflections on how co-creation and participatory processes can create possibilities for a sustainable and equitable future.

Over the last few decades, the architecture, engineering, construction and operation (AECO) sector did not follow the technological evolution observed in other sectors. Although there have been technological innovations, which include BIM and the Protocol for Standardization of Technical Construction Information (ProNIC

Face à metamorfose que se presencia na região da Avenida Almirante Reis, este capítulo discute a sua correlação com a criação de um novo discurso sobre a diversidade sociocultural. A partir do apelo a determinadas expressões — por exemplo, mundo e mundos — para enunciar a diversidade local, sugere-se a crescente transfiguração do discurso e a conexão com a economia cultural amplamente estimulada pela intervenção ali protagonizada. No desenvolvimento desta reflexão, privilegia-se o discurso produzido pela comunicação social.
