The growing adoption of shared mobility services provides a sustainable alternative to private vehicle use and offers a potential solution to urban challenges such as traffic congestion, environmental degradation, and inefficient land use. This study examines how service quality attributes, perceived usefulness, and environmental benefits influence user satisfaction and loyalty across multiple shared mobility modes, including shared electric cars, bicycles, and scooters. Drawing on survey data collected from 331 shared mobility users across Inverness (Scotland), Greater Manchester (England), and Dublin (Ireland), we apply Partial Least Squares Structural Equation Modelling (PLS-SEM) to identify the key determinants of satisfaction and loyalty. An Importance–Performance Map (IPM) analysis is used to prioritise areas for service improvement, while multigroup analysis highlights differences in user preferences across transport modes and geographic contexts. The results show that service quality attributes, specifically accessibility, affordability, safety, ease of use, and convenience, play a central role in shaping user satisfaction, which in turn directly increases loyalty. Perceived environmental benefits also display a significant positive influence on satisfaction, underscoring the importance of sustainability considerations in user decision-making. By analysing satisfaction and loyalty across diverse shared mobility modes and three European cities, this study makes a significant step forward in advancing the existing knowledge in shared mobility literature. The findings offer operators and policymakers actionable guidance to optimise service delivery, strengthen user retention, and promote the uptake of sustainable transport solutions.

Electric mobility hubs (eHUBS) represent an innovative approach to providing diverse shared electric transportation options, aimed at curbing private car use, and mitigating associated environmental impacts. Assessing the impact of eHUBS on travel choices across different cities requires significant resource and time investment due to the need for localized data collection and model development. This paper proposes a potential solution to this challenge by investigating the transferability of mode choice models originally developed for eHUBS in Amsterdam to predict behaviour towards eHUBS in Manchester. Multinomial Logit (MNL) and mixed logit models were transferred using four different procedures, and their effectiveness was evaluated using three assessment measures. The findings indicate that a scaled mixed logit model with an updated Alternative Specific Constant (ASC) outperforms other models in terms of its transfer effectiveness, both for disaggregate and aggregate assessment measures. The interplay between transfer procedures and assessment measures also was examined, with results indicating enhancements in disaggregate transferability measures with the 'scaling' transfer procedure, while 'updating the Alternative Specific Constants (ASCs)' improved predictions of aggregate mode shares. Following the analysis, the paper presents an in-depth discussion to provide a nuanced understanding of transferability and thus offers valuable insights for researchers planning future studies and practical considerations for policymakers.

Electric mobility hubs (eHUBS) are locations where multiple shared electric modes including electric cars and e-bikes are available. To assess their potential to reduce private car use, it is important to investigate to what extent people would switch to eHUBS modes after their introduction. Moreover, people may adapt their behaviour differently depending on their current travel mode. This study is based on stated preference data collected in Amsterdam. We analysed the data using mixed logit models. We found that users of different modes not only have varied general preferences for different shared modes but also have different sensitivity for attributes such as travel time and cost. Public transport users are more likely to switch to eHUBS modes than car users. People who bike and walk have strong inertia, but the percentage choosing eHUBS modes doubles when the trip distance is longer (5 or 10 km).

Shared electric mobility hubs, or eHUBs, offer users access to a range of shared electric vehicles on demand. However, little is currently known about what the characteristics of potential users of this novel type of shared mobility are. This makes it difficult to plan the location of hubs and to provide facilities, which ultimately will determine their success. This paper therefore seeks to identify potential users based on an in-depth case study of a representative sample of the Municipality of Amsterdam population. The analysis employed an attitudinal market segmentation approach supported by the Theory of Diffusion of Innovations (DOI). The analysis identified four specific target groups, each with a different propensity to use eHUBs in the future. In our sample, two groups expressed an interest in using eHUBs. The first group consists of highly educated and non-car owning young adults (19% of the sample), whereas the second group shows a higher level of car ownership and a greater number of households with children (69% of the sample). The two remaining groups comprise the majority of laggards (52%), despite only representing 12% of the sample. They tend to be older, less educated, and live in a household without children. The four groups are further distinguished based on their current shared mobility use, traveler identity, and perceived barriers to using shared electric vehicles. Finally, general recommendations to practitioners and policymakers to increase the uptake of shared mobility, including paying attention to the availability, cost, and convenience of shared mobility options, are provided.
