Abstract(s)
Este trabalho apresenta o estudo e análise de viabilidade da implementação de Cooperative Intelligent
Transport Systems (C‐ITS) nas infraestruturas rodoviárias geridas pela Ascendi. Com o
avanço das tecnologias de mobilidade conectada, a integração de soluções C‐ITS representa uma
oportunidade significativa para melhorar a segurança rodoviária, otimizar a gestão do tráfego e
promover a sustentabilidade ambiental.
A dissertação foi estruturada em diversas fases. Iniciou‐se com uma revisão aprofundada do estado
da arte, onde estão especificadas as tecnologias C‐ITS, como o Intelligent Transport Systems
‐ G5 (ITS‐G5) e o Cellular Vehicle‐to‐Everything (C‐V2X), bem como as mensagens Cooperative
Awareness Message (CAM) e Decentralized Environmental Notification Message (DENM), que
são essenciais para a comunicação em tempo real entre veículos e infraestrutura. Foram também
analisadas as diretivas europeias mais recentes, incluindo a Diretiva 2023/2661, que orienta
a interoperabilidade das soluções a nível europeu.
Seguidamente, foi elaborada uma arquitetura e três soluções distintas para a implementação do
sistema. Duas dessas soluções basearam‐se em tecnologias e arquiteturas já existentes no mercado.
A terceira solução, por sua vez, consistiu numa proposta, com o desenvolvimento de uma
arquitetura técnica específica para um sistema autónomo alimentado por energia solar, focado
numa solução integrada para a Road Side Units (RSU). Esta proposta incluiu o dimensionamento
detalhado dos principais componentes do sistema.
Com base nas três soluções desenvolvidas, foi realizada uma análise comparativa considerando
critérios técnicos e financeiros, da qual resultou a proposta de uma solução para o projeto. Posteriormente,
foi efetuada uma análise económico‐financeira detalhada com o objetivo de avaliar a
rentabilidade da implementação, englobando os custos associados, as amortizações e as estimativas
de retorno do investimento. Esta abordagem permitiu fundamentar de forma mais rigorosa
a tomada de decisão quanto à solução a adotar.
Este trabalho tem assim como principal objetivo fornecer uma base sólida para a implementação
de soluções C‐ITS no contexto das autoestradas da Ascendi, promovendo uma mobilidade mais
segura, eficiente e sustentável.
This document presents the study and feasibility analysis of the implementation of Cooperative Intelligent Transportation Systems (C‐ITS) in the road infrastructures managed by Ascendi. With the advance of connected mobility technologies, the integration of C‐ITS solutions represents a significant opportunity to improve road safety, optimize traffic management and promote environmental sustainability. The dissertation was structured in several phases. It began with an in‐depth review of the state of the art, specifying C‐ITS technologies such as ITS‐G5 and C‐V2X, as well as CAM and DENM messages, which are essential for real‐time communication between vehicles and infrastructure. The latest European directives were also analysed, including Directive 2023/2661, which guides the interoperability and standardization of solutions at European level. Next, an architecture and three different solutions were devised for implementing the system. Two of these solutions were based on technologies and architectures already on the market. The third solution, in turn, consisted of a proposal, with the development of a specific technical architecture for an autonomous solar‐powered system, focused on an integrated solution for the RSU. This proposal included detailed sizing of the system’s main components. Based on the three solutions developed, a comparative analysis was carried out considering technical and financial criteria, which resulted in the proposal of a solution for the project. Subsequently, a detailed economic and financial analysis was carried out in order to assess the profitability of the implementation, including the associated costs, amortizations and return on investment estimates. This approach provided a more rigorous basis for making a decision on the solution to be adopted. The main aim of this work is to provide a solid basis for implementing C‐ITS solutions on Ascendi’s highways, promoting safer, more efficient and sustainable mobility.
