Clustering users and non-users of shared and private e-bikes and e-scooters acr...
Adorean, Emanuel-Cristian; Nofre, Jordi; Moura, FilipeThis study examines typologies of users and non-users of electric micromobility (e-micromobility) - covering private and shared e-bikes and e-scooters - across three European cities: Lisbon (Portugal), Madrid (Spain), and Cluj-Napoca (Romania). Based on 2304 survey responses, a multi-stage analytical framework was applied, combining Principal Component Analysis (PCA) with hierarchical clustering (Ward.D2) and s...
Understanding the expectations of parents regarding their children's school com...
Queiroz, Mariza Motta; Roque, Carlos; Moura, Filipe; Maroco, J. P.Parents’ perceptions regarding public transport and active modes influence the youth’s acceptance and support for sustainable school commuting. Urban mobility surveys can gather such insights by utilizing closed and open-ended questions. The latter, particularly, holds the potential for nuanced expectations and insights from Public Transport (PT) users, often absent in closedended responses. This paper proposes...

Geographical Distribution of Solar Urban Potential for Vehicle Integrated Photo...
Brito, Miguel; Santos, Teresa; Amaro e Silva, Rodrigo; Pera, David; Moura, Filipe; Rocha, JorgeSolar-powered electric vehicles can accelerate the transition to electric mobility, reducing charging needs and operating costs. In the urban environment, however, their potential is somewhat reduced by shadowing from neighbouring buildings. Here we estimate the irradiation losses and solar extended driving range for anywhere on the globe using an empirical model based on numerical simulation of solar radiation...
Urban solar potential for vehicle integrated photovoltaics
Centeno Brito, Miguel; Santos, Teresa; Moura, Filipe; Pera, David; Rocha, JorgeIntegrating solar photovoltaics in electric vehicles can reduce operating costs and extend the driving range. It is particularly appropriate for urban mobility due to the relatively short typical daily travels of urban vehicles. However, shadowing cast by buildings will reduce the solar irradiation falling on the vehicle, reducing its PV generation. This study assesses the solar potential of onboard solar for r...
School commuting: the influence of soft and hard factors to shift to public tra...
Queiroz, Mariza Motta; Celeste, Pedro; Moura, FilipeSchool commuting is critical for modern societies considering its potential and long-lasting impacts in travel behaviour of younger generations, today and in the future. Besides positive health impacts, it is crucial to expose students to more sustainable modes (e.g., walking, cycling, public transport) to form future adults with more sustainable mobility decisions. Despite the vast research on school commuting...
THE DIGITAL PEDESTRIAN NETWORK IN COMPLEX URBAN CONTEXTS: A PRIMER DISCUSSION O...
Cambra, Paulo Jorge; Gonçalves, Alexandre; Moura, FilipeA safe and accessible pedestrian network is essential to an equitable and sustainable urban mobility system. The importance and benefits of pedestrian-friendly urban environments has been widely addressed in transport research, yet most studies focusing in pedestrian accessibility use available street network datasets that do not represent effectively the pedestrian environment. In some cases the use of street ...

Scattering of spherically symmetric d-dimensional α′−corrected black holes in s...
Moura, FilipeWe study scattering of minimally coupled massless scalar fields by non-extremal spherically symmetric black holes in d dimensions with string-theoretical α′ corrections. We then obtain a formula for the low frequency absorption cross section for every black hole of this kind, which we apply to known black hole solutions. We compare the α′ corrections for the absorption cross section with those for the black hol...
Tensorial perturbations and stability of spherically symmetric d-dimensional bl...
Moura, FilipeWe compute the tensorial perturbations to a general spherically symmetric metric in d dimensions with string–theoretical corrections quadratic in the Riemann tensor, from which we derive their respective potential. We use this result to study the stability of corresponding black hole solutions under such perturbations.
