Abstract: This paper presents an innovative service for river flow forecasting and its demonstration in two dam-controlled rivers in Portugal, Tejo, and Mondego rivers, based on using Multilayer Perceptron (MLP) models to predict and forecast river flow. The main goal is to create and improve AI models that operate as remote services, providing precise and timely river flow predictions for the next 3 days. This paper examines the use of MLP architectures to predict river discharge using com...

The Forte das Memórias (Coastal Memory Fort) project aims to revitalise tangible and intangible heritage through the safeguarding of the 17th century fort of Nossa Senhora dos Anjos de Paimogo, Lourinhã (Portugal). Located on the cliffs of Paimogo Beach – a place marked by the historical landing of the Duke of Wellington’s forces during the Napoleonic Wars – the fort stands as a prime example that brings together the best of Portuguese military architecture of former eras. The project endeavo...

In the digital age, preserving intangible cultural heritage holds paramount importance. This proposal delves into the synergy of cultural preservation and digital innovation, focusing on the coastal region's intangible heritage. We present a pioneering approach to curate and disseminate untold stories through immersive digital narratives. Our project integrates interactive multimedia elements within a proposed coastal memory fort, fostering engagement and learning. The narrative design encaps...

The Barbarie spit (Langue de Barbarie) is a 100–400 m-wide West-Africa coastal barrier that has fluctuated in length between 10 and 30 km over the last century (Anthony, 2015). The changes in length reflect the variable position of the Senegal river mouth, where rates of spit growth vary greatly (100 to 700 m/year), depending on variations in wave characteristics, river discharge and river mouth dynamics, combined with barrier-breaching events (Bergsma et al., 2020). The Barbarie sandy barr...

ShorelineS is a recent coastline evolution model allowing for extreme coastline curvatures and spit formation at high-angle wave incidence. This paper investigates ShorelineS’s capabilities in reproducing longshore sediment rates, spit elongation and inlet migration, such as those observed at Langue de Barbarie, in Senegal. Moreover, it addresses the influence of the sediment transport formulation and other model parameters on the representation of shoreline instabilities downdrift of the Sen...

Road pavements are vital for transportation infrastructure, yet they deteriorate over time due to traffic loads and environmental factors, resulting in cracks and damage. This paper introduces an innovative method for crack detection on road pavements using digital imagery. Our approach incorporates geo-localization, annotates, characterizes, and quantifies crack severity. This empowers experts to monitor crack progression, a critical element in pavement management. The methodology allows for...

The concept of 15-min cities has recently received a lot of attention in recent research. However, the clear definition of a measurement for this concept has not yet been done at a neighborhood and city level across all continents and encompassing topological constraints. Yielding the question if 15 min is even the right indicator. In this study, we propose a method for determining how closely a city adheres to this concept using Open Data. We also propose an optimized method for generating c...

Rivers are among the most endangered ecosystems in the world, although they play a fundamental role in the urban environment, for public health and wellbeing. The role of rivers in the production of urban spaces is one of the research strands within the scope of the Ibero-American Network RUN | Naturalized Urban Rivers (CYTED - www.run.ulusofona.pt). RUN combines knowledge and experiences about the regeneration processes of rivers under strong pressure in urban areas with nature-based solut...

Neste relatório, do projeto europeu MOVING TOGETHER, apresenta-se um plano geral para as atividades de demonstração e visitas técnicas a realizar no âmbito da Conferência internacional TRA2022, a ter lugar em Lisboa. Este plano foi elaborado com o objetivo de proporcionar experiências significativas e relevantes aos participantes, além de ampliar a visibilidade dos Demonstradores e de toda a conferência TRA LISBOA 2022.

This report proposes two cross-cutting methodologies for joint exploitation of information for monitoring and modeling in coastal regions taking advantage of the products developed and enhanced in the scope of the CONNECT project, namely the CONNECT coastal service (Rodrigues et al., 2024). The workflow for their implementation is demonstrated in the Tagus estuary taking advantage of the results of this project. The proposed cases are: 1) a methodology for establishing forecast system grid ...

Apresentação efetuada a convite ao evento TimberWorqs abordando as implicações no processo de marcação CE de produtos de construção, derivadas da publicação do novo Regulamento de UE relativo a Produtos de Construção (Regulamento 2024/3110).

Road safety key performance indicators (KPIs) provide essential insights into factors associated with crash and injury risks. The Trendline project, involving 25 EU Member States, focuses on collecting and analyzing road safety KPIs to inform policy decisions. In addition to standard KPIs recommended by the European Commission, the project explores ten experimental KPIs, including road users’ compliance with traffic rules at pedestrian crossings and intersections. Compliance with traffic r...

Over the past 50 years, global plastic production has surged exponentially. Around 40% of this plastic is used for packaging, most of which is single-use, while 20% is used in construction. Despite the vast quantities produced, only about 6% of discarded plastics are properly recycled, 10% are incinerated, and the majority are disposed of without proper management. With low recycling rates and some plastics being non-recyclable or with limited recycling cycles, it is important to explore new ...

Este trabalho analisa acidentes envolvendo pedestres em travessias urbanas, buscando identificar fatores de risco e propor medidas de mitigação com base em modelos de previsão de acidentes (MPAs). A pesquisa recorre a Redes Neurais Artificiais (RNA) aplicadas a uma base de dados da Autoridade Nacional de Segurança Rodoviária (ANSR) referente ao período de 2017 a 2021. Embora os modelos apresentem alta taxa de acerto, o poder discriminativo foi limitado pela predominância de casos de feridos l...

The abstract outlines the new Portuguese design standards for urban roads, focusing on pedestrian infrastructure. It highlights the need for inclusive and safe urban design, considering pedestrian diversity and vulnerability. Aligned with PENSE 2020 and the Safe System principles, these standards enhance road safety, particularly for vulnerable users. They define pedestrian pathways within the public domain, including sidewalks, paved routes, and crossings, while acknowledging informal pedest...

This abstract aims to provide an overview of the new Portuguese design standards for urban roads, with a particular focus on the pedestrian infrastructure. Walking, as one of the most fundamental traffic modes, emphasizes the importance of thoughtful and inclusive urban road design that effectively meets the mobility needs of all citizens. The development of the pedestrian infrastructure must consider the heterogeneous characteristics of pedestrians and their varying levels of vulnerabilit...

Intersections are considered to be high-risk areas due to noncompliance with traffic rules. Failure to yield right of way and running red lights are major issues, but improper turning manoeuvres, like illegal U-turns and improper signalling, are also contributor factors to accidents. Vulnerable road users are particularly at risk at these locations, as these violations may result in severe injuries and congestion. The EU has set ambitious road safety goals in order to reduce the number of ki...

Most of European cities face increasing problems caused by excessive traffic of conventional fuel-based transport modes. To reverse this situation, sustainable urban mobility policies have been promoting soft modes of transport, such as walking. Despite the advantages of walking in reducing traffic congestion and pollution, cities have not always evolved to accommodate the needs of pedestri-ans. According to the European Commission, in 2020, 20% of road fatalities in the European Union (EU) a...
