Orozco-fontalvo, Mauricio, André Soares Lopes, David Vale & Filipe Moura, (2024). IMPReSS : A comprehensive method to classify MaaS systems. Transport Policy, 155, 234–241
Abstract: Mobility as a Service (MaaS) can improve urban mobility by reducing car ownership and promoting multimodal transport through a single mobility app that provides trip planners, booking, ticketing, and payment for different modes and bundles. However, not all existing MaaS (or potential MaaS) systems provide a fully integrated system. Several authors have proposed different methodologies to assess MaaS integration. However, these approaches have some limitations regarding the scalability or characterization of the systems, making it hard to compare them, as the current approaches are all incremental. In this work, we propose a new method called IMPReSS, a binary coding approach that assesses several dimensions of MaaS: Information, Multimodality, Payment, Reservation, Subscription, and Societal goals. It allows proper classification and comparison of different systems, using the societal goals as a cornerstone for its evaluation. Also, we propose a complementary scoring system based on the IMPReSS topology. This qualitative and quantitative methodology will allow practitioners and researchers to characterize, identify, and adequately assess transportation services and their potential to become a fully integrated MaaS system. Our results show that mature MaaS systems with public authorities involved and some often excluded from MaaS discussion systems are ranked higher, while some wrongly called MaaS apps are ranked at the bottom. In summary, it assesses systems from a different and flexible perspective.

Vale, David & André Soares Lopes (2023) Accessibility inequality across Europe: a comparison of 15-minute pedestrian accessibility in cities with 100,000 or more inhabitants. npj Urban Sustainaibility, 3.
Abstract: Active accessibility is a paramount objective of sustainable urban development policies. Recently, the 15-minute city concept emphasized this framework by stressing proximity as a key urban feature. In this paper, we use two accessibility indicators —cumulative opportunities (total destinations) and Variety (number of different types of opportunities)—to evaluate pedestrian accessibility, using a 15-minute threshold, in a sample of European cities with 100,000 or more inhabitants, and measure within-city and between-city inequality, by calculating pseudo-Gini coefficients. Our results show not only that European cities are not 15-minute cities yet but also that there is significant inequality within them, although less so in cities with high Variety. Our cross-city comparison found diminishing returns between total destinations and population density and between Variety and density. Our findings suggest that European cities can increase pedestrian accessibility and reduce internal inequality by increasing the Variety of opportunities accessible by foot, along with improvements to pedestrian infrastructure.

Lopes, André Soares, Maurício Orozco-Fontalvo, Filipe Moura & David Vale, (2023) Mobility as a service and socio-territorial inequalities?: A systematic literature review. Journal of Transport and Land Use, 16, 215–240.
Abstract: Mobility as a service is a potential solution to mobility problems; however, it raises concerns about its relationship with socio-territorial inequalities (STIs). This paper contains a systematic literature review of real-world MaaS applications and their effects on STIs. From the principle of distributive justice, we adopted the Resources, Opportunities, Outcomes, and Wellbeing (ROOW) approach to assess cases. From 2009 papers on MaaS, we identified 20 real-world applications that considered equity impacts. Most studies were undertaken in Europe and Asia, neglecting countries in South America, Africa, and other low-income countries. They did not quantify the societal advantages of MaaS, while only a handful investigated the influence of MaaS over STIs. Results indicate that MaaS schemes contain at least three factors that may drive inequality: the lack of basic resources to enter the system, the systems’ limited geographic coverage, or MaaS users may not gain from the system’s intended accessibility benefits. In conclusion, MaaS could improve trip planning and access to new modes and low-density areas, but it is still perceived as expensive and only accessible to digitally literate people. This should be considered when defining MaaS governance, which remains (to date) underdeveloped, hindering private-public collaboration.
