Shared autonomous mobility-on-demand (SAMoD) offers the opportunity to make local public transport more sustainable and individual but hinges on public acceptance. While previous studies often rely on abstract scenarios, convenience samples, or laboratory settings, this paper addresses these three central research gaps. Using a Berlin-wide, randomized household survey (n = 567, weighted), this study investigates the stated preference acceptance of a specific Level-4 shuttle service. Usage related acceptance data is collected through an extended UTAUT2 model and complemented by usage independent attitudes and expectations, mobility attitudes and behaviour, and sociodemographics.Results reveal that two-thirds of participants express a fundamental intention to use the service, with one-third intending regular use. The multiple regression model explains 79% of the variance in usage intention, with performance expectancy, hedonic motivation, perceived safety, and effort expectancy emerging as significant predictors. Beyond usage intention, the study captures that over 60% of respondents expect the service to enhance public transport attractiveness and contribute to climate protection, while concerns persist regarding traffic relief and social safety. The results further indicate a moderate potential for behavioural change and a contribution for a shift in urban mobility.The findings underscore the importance of differentiated acceptance research for the design and implementation of autonomous mobility services, offering actionable insights for transport planners and policymakers.
