These sources collectively examine Mobility as a Service (MaaS), exploring its definition, potential benefits, challenges, and user acceptance. Several documents, including a white paper on regulatory models and an analysis focused on the Global South, define MaaS as the integration of various transport services into a single, accessible, on-demand digital platform, facilitating multimodal planning, booking, and payment. Research on user behavior indicates that while MaaS has the potential to reduce private car dependence and promote sustainable travel, initial adoption rates among car owners can be low, often due to concerns about shared vehicle availability, convenience, and human element externalities such like crowding or discourtesy. A significant portion of the material addresses the critical role of data in MaaS, emphasizing the need for open data standards, robust security measures, and harmonized regulatory frameworks to foster collaboration among MaaS operators, government agencies, and transport providers. Findings suggest that factors such as cost incentives, added value, and trust in functionality are key drivers for MaaS acceptance and its subsequent impact on travel behavior.
