The specific features and requirements of island regions and rural areas make Mobility as a Service (MaaS) an attractive and evolving concept in the realm of Intercity/Rural/Island transportation. The primary goal of this research is to provide qualitative insights relative to the added value and development of MaaS for the previously mentioned transport services through a case study from Greece, a country with approximately 250 inhabited islands. In island settings, the primary societal motivation for MaaS is to enhance the accessibility of islands and improve individuals' access to multiple transport services. MaaS is found to have a strong potential to act as an enabler for more efficient transport and better accessibility to remote/island locations, acting in a complementary manner with currently applied “external” measures such as the Greek “Transport Equivalent”. To further assess the potential, development and impact of MaaS a focus group comprised by key-representatives from industry and academia stakeholders is created. The MaaS Ecosystem, as described by the experts, is comprised of the MaaS Provider, all the intercity/rural/island transport providers currently operating in the Greek market, MaaS Enabling entities (associations, regulators, investors, research institutions), the Integration Drivers and the customers. The issue of transport providers’ liability in case of disruptions and existing market regulations constitute, according to the results, an important challenge towards development of an Intercity MaaS, which needs to be addressed by legislative studies in a pan-European level. Most likely user groups for Intercity/Rural/Island MaaS are young people and digitally educated people, whilst less likely patronage groups are the elderly and “vulnerable” population groups. Relative to the external environment, high degree of fragmentation of the intercity transport industry combined by “autonomous” behavior of actors (“silo effect”) appears to be the greatest threat towards MaaS whilst anticipated capital investments in infrastructure and vehicles, which are foreseen in the proxime future, are the greatest opportunities.

This article assesses the potential of Mobility as a Service in passenger maritime transport from the supply perspective by collecting and analyzing data provided by interviews to key experts in passenger transport from both industry and academia. “Mobility as a service” in passenger maritime transport (also in this article referred as “Maritime MaaS”) describes the integration of passenger maritime services with land mobility into a single mobility service delivered through a unique platform for planning, booking, ticketing, and payment. The scope of this article is to explore the potential interest of mobility service providers to develop a MaaS that has as a backbone coastal shipping at the Aegean Archipelagos, in Greece. The Maritime MaaS ecosystem with its key actors is identified, while the perceived challenges, opportunities, and benefits envisaged by the adaptation of this innovative concept from urban transport to the maritime sector are recorded. Computer-assisted interviews were performed at a panel of 17 experts representing different types of decision makers. Participants were selected according to their current industry position or their academic profile. A content analysis with the use of NVIVO was conducted, followed by a SWOT (strengths, weaknesses, opportunities, and threats) analysis based on the experts’ input, in order to assess the MaaS business environment. Results indicate that the maritime transport sector is relatively ready to adopt MaaS from a technological readiness perspective, while land transport seems to be in a lower level of technological readiness. PAYG (pay as you go) MaaS business model is preferred than a “MaaS package” model by most stakeholders. Finally, main challenges toward MaaS implementation are the discrepancies in reliability of service among different transport modes and the ferry fleet operational flexibility ceilings that are imposed by legal framework for ferry routings in Greece.

This study assesses the exposure of the 155 Greek seaports to marine flooding and extreme heat under climate change. Flood exposure was estimated through a threshold approach that compared projected mean and extreme sea levels to high-resolution port quay elevation data. It was found that while relatively few ports will face quay inundation, the majority will experience operational disruptions due to insufficient freeboard for berthing of commercial vessels under both the mean (80%) and extreme sea (96%) levels by 2050. For selected ports, 2-D flood modelling was undertaken that showed that the used ‘static’ flood threshold approach likely underestimates flood exposure. Future heat exposure was studied through the comparison of extreme temperature and humidity projections to operational and health/safety thresholds. Port infrastructure and personnel/users will be exposed to large material, operational and health risks, whereas energy demand will rise steeply. Deadly heat days (due to mean temperature/humidity combination) will increase, particularly at island ports: 20% of Greek ports might face more than 50 such days annually by end-century. As ports are associated with large urban clusters, these findings suggest a broader health risk. Our findings suggest an urgent climate adaptation need given the strategic socio-economic importance of ports.
