The continuous growth of tourism has important environmental impacts and transports account for a large proportion of the CO₂ emissions generated by tourists. Understanding the motivations and characteristics of collective transport users in contemporary cities may contribute to promote more sustainable forms of tourism. Based on an extensive questionnaire to international tourists in Barcelona, this study employs a multinomial logistic regression to explore the links among visitors' characteristics, motivations, and means of transportation, while an ordinal logistic regression is applied to investigate whether the preference for collective transport has an impact on the satisfaction with the trip. The novelty of our approach is testing the hypothesis that the choice of collective transports is more related to trip motivations (professional, leisure, or personal) than to socio-demographic or personal characteristics of tourists. The results show that professional travelers are more oriented to the use of private cars, but they prefer collective transports when the length of stay is higher and combined with other trip motivations. Also, using collective transports is linked to high satisfaction with the visit for the tourists using this form of transportation. This study puts forward policy implications and suggestions for future research directions, in particular regarding the utilization of non-motorized forms of transportation cities.

旅游业的持续增长具有重要的环境影响，交通运输占 CO ₂的很大比例游客产生的排放。了解当代城市集体交通用户的动机和特征可能有助于促进更可持续的旅游形式。本研究基于对巴塞罗那国际游客的广泛问卷调查，采用多项逻辑回归来探索游客的特征、动机和交通方式之间的联系，同时采用序数逻辑回归来调查对集体交通的偏好是否有影响。影响旅行的满意度。我们的方法的新颖之处在于检验集体交通工具的选择更多地与旅行动机（专业、休闲或个人）相关的假设，而不是与游客的社会人口统计或个人特征相关。结果表明，职业旅行者更倾向于使用私家车，但当停留时间较长并结合其他旅行动机时，他们更喜欢集体交通工具。此外，使用集体交通工具与使用这种交通工具的游客的访问满意度有关。本研究对未来的研究方向提出了政策启示和建议，特别是关于非机动交通城市的利用。
