Following the implementation of temporary pop-up bike lanes in Berlin, traffic counts by the city administration show an increased number of cyclists. This present paper aims to understand reasons behind this observation. To this end, we focus on the role of mobility-related descriptive social norms as mediators of this effect. Results from one correlational and two experimental online studies are reported. The correlational study confirms the expected association of mobility-related descriptive social norms and self-reported mobility behavior. Moreover, it demonstrates that, as expected, mobility-related descriptive social norms reliably reflect differences in cities' objective transport structure and mediate the impact of these infrastructural differences on mobility behavior. Results from two online experiments provide additional causal evidence that participants use the visual cues provided by manipulated photos to form their perceived mobility-related descriptive social norms. Furthermore, the second online experiment provides evidence that the combination of infrastructural cues and observable mobility behavior has the strongest impact on perceived mobility-related descriptive social norms.
在柏林实施临时弹出式自行车道后，城市管理部门的交通流量统计显示骑自行车的人数有所增加。本文旨在探究这一现象背后的原因。为此，我们重点关注与出行相关的描述性社会规范作为这种效应中介的作用。报告了一项相关性研究和两项实验性在线研究的结果。相关性研究证实了与出行相关的描述性社会规范与自我报告的出行行为之间的预期关联。此外，研究表明，正如预期的那样，与出行相关的描述性社会规范可靠地反映了城市客观交通结构的差异，并介导了这些基础设施差异对出行行为的影响。两项在线实验的结果提供了额外的因果证据，表明参与者利用经过操纵的照片所提供的视觉线索来形成他们对与出行相关的描述性社会规范的认知。此外，第二项在线实验提供的证据表明，基础设施线索和可观察到的出行行为的结合对与出行相关的描述性社会规范的认知影响最大。
