Resumo(s)
Num período em que a ação climática ganha cada vez maior protagonismo, a
mobilidade revela-se como um fator-chave para reduzir a emissão de gases com efeito de
estufa. Os sistemas de transporte metropolitanos podem desempenhar um papel
fundamental na movimentação de passageiros de forma mais sustentável, oferecendo um
serviço de elevada capacidade e frequência, em território densamente povoado.
Na Área Metropolitana de Lisboa (AML), o sistema de transportes públicos não
consegue responder às necessidades da população, resultando numa utilização
predominante do automóvel e consequente elevado nível de congestionamento, poluição do
ar e sonora. De forma a contrariar essa tendência, interessa promover meios de transporte
público de elevado desempenho, em particular o modo ferroviário.
É objetivo desta dissertação identificar as lacunas na rede de transportes públicos na
AML explorando propostas de melhoria da rede ferroviária metropolitana.
Com base na doutrina e nas melhores práticas reportadas na literatura, identificaram-
se os focos com maiores carências na mobilidade, recorrendo a uma metodologia baseada em
SIG. Identificadas 8 lacunas principais, apresentaram-se 18 soluções, incluindo linhas novas
a extensões de redes existentes. Conclui-se que é possível ampliar de 33% para 65% a
população ao alcance de um modo ferroviário, reduzindo entre 11% a 15% a circulação de
veículos individuais na AML. Perspetiva-se que numa lógica de rede integrada e intermodal
seja possível melhorar ainda estes indicadores.
At a time when climate action is becoming increasingly important, mobility is proving to be a key factor in reducing greenhouse gas emissions. Metropolitan transport systems can play a fundamental role in moving passengers in a more sustainable way, offering a high-capacity and frequent service in densely populated territory. In the Lisbon Metropolitan Area (AML), the public transport system is unable to meet the needs of the population, resulting in a predominant use of the car and a consequent high level of congestion, air and noise pollution. In order to counteract this trend, it is important to promote high-performance public transport, particularly rail. The aim of this dissertation is to identify the gaps in the AML public transport network and explore proposals for improving the metropolitan rail network. Based on the doctrine and best practices reported in the literature, the areas with the greatest shortcomings in mobility were identified using a GIS-based methodology. After identifying 8 main gaps, 18 solutions were presented, including new lines and extensions to existing networks. The conclusion is that it is possible to increase the population within reach of rail from 33% to 65%, reducing the circulation of individual vehicles in the AML by between 11% and 15%. It is hoped that with an integrated, intermodal network it will be possible to improve these indicators even further.
