This paper describes the characteristics of former regular users of public transport in the metropolitan area of Lisbon. It also examines why these people stopped using public transport and explores what would make them become regular users again. The empirical results revealed significant socio-demographic differences between current and ex-regular users, namely in relation to gender and social level. Differences were also found in travel characteristics, car ownership, and satisfaction with the transit service. The main reasons given by ex-regular users for no longer using public transport included changes in their lives (e.g., change in workplace/residence/ school or becoming unemployed) and the availability of alternative transport (e.g., company car). Although the likelihood of becoming a regular user again was very low (27%), the strongest potential motive for doing so was a change in workplace/residence/school. Based on the study’s empirical results, managerial implications for the public transport service are addressed in the conclusion.

公共交通的非常规用户：他们离开和返回的原因

本文介绍了里斯本大都市地区以前公共交通的常规用户的特征。它还研究了为什么这些人停止使用公共交通工具，并探讨了使他们再次成为常规用户的原因。实证结果表明，当前用户和非常规用户之间在社会人口统计学上存在显着差异，即在性别和社会水平方面。在出行特征，汽车拥有量和对公交服务的满意度方面也发现差异。非常规用户不再使用公共交通工具的主要原因包括生活变化（例如工作场所/居住/学校的变化或失业）和其他交通工具（例如公司的汽车）的可用性。尽管再次成为普通用户的可能性很小（27％），这样做的最大动机是改变工作场所/居住/学校。根据研究的经验结果，结论中论述了管理对公共交通服务的影响。
