Mobile phones have become a ubiquitous phenomenon on public transport. However, little attention has been given to the effect of mobile communication on perceived security on public transport. This paper develops a model of social presence and perceived security in order to understand the widespread use of mobile phones on public transport as well as its effects. The first part of the model suggests a mediating role of social presence to understand how perceived security motivates mobile communication. The respective hypotheses are tested with a representative survey (N = 2,267), and the results support the mediating role of social presence. The second part of the model assumes that social presence is not only a motive to use mobile communication but also helps to improve perceived security. Based on a 2-week mobile experience sampling with 86 participants and 1,264 measurement points, the effect of mobile communication and social presence obtained, as well as individual and situational factors on perceived security were tested. The respective hypotheses were partially supported but also suggest that other coping strategies might be of relevance to fully understand the relationship between mobile communication and situational perceived security. Besides the academic insights, these results suggest that public transport operators should consider expanding mobile phone coverage in their vehicles and stations to improve perceived security and make their services more attractive.

公共交通上的移动通信、社交存在和感知安全

手机已成为公共交通工具上无处不在的现象。然而，很少有人关注移动通信对公共交通感知安全的影响。本文开发了一个社会存在和感知安全的模型，以了解移动电话在公共交通中的广泛使用及其影响。该模型的第一部分提出了社会存在的中介作用，以了解感知安全如何激发移动通信。各自的假设都通过具有代表性的调查 (N = 2,267) 进行了测试，结果支持社会存在的中介作用。模型的第二部分假设社交存在不仅是使用移动通信的动机，而且有助于提高感知安全性。基于对 86 名参与者和 1,264 个测量点进行的为期 2 周的移动体验抽样，测试了移动通信和社交临场感的影响，以及个人和情境因素对感知安全性的影响。各自的假设得到部分支持，但也表明其他应对策略可能与充分理解移动通信与情境感知安全之间的关系有关。除了学术见解，这些结果表明，公共交通运营商应考虑扩大其车辆和车站的移动电话覆盖范围，以提高感知安全性并使其服务更具吸引力。以及对感知安全性的个人和情境因素进行了测试。各自的假设得到部分支持，但也表明其他应对策略可能与充分理解移动通信与情境感知安全之间的关系有关。除了学术见解，这些结果表明，公共交通运营商应考虑扩大其车辆和车站的移动电话覆盖范围，以提高感知安全性并使其服务更具吸引力。以及对感知安全的个人和情境因素进行了测试。各自的假设得到部分支持，但也表明其他应对策略可能与充分理解移动通信与情境感知安全之间的关系有关。除了学术见解，这些结果表明，公共交通运营商应考虑扩大其车辆和车站的移动电话覆盖范围，以提高感知安全性并使其服务更具吸引力。
