Transportation infrastructure that accommodates the needs of active mode users is an essential element of sustainable and just urban mobility transitions. Safety is a major factor influencing bicyclist behavior, and understanding how safety is perceived by traffic participants can support urban designs that will attract greater shares of active travelers. This paper evaluates the stated preferences of motorists, cyclists, and pedestrians for safe transport infrastructures. It relies on data collected by the non-governmental organization FixMyBerlin in cooperation with a German newspaper, Berliner Tagesspiegel. 21,401 participants assessed a total of 1900 different traffic situations, generating a sample of 468,379 opinions on street design elements including major streets, side streets and pavements. Results point at the importance of wide bicycle tracks and the separation of cyclists from motorized and pedestrian traffic. The removal of parking next to bicycle lanes also has great importance for improving perceptions of safety. The data offers detailed insight into key elements of urban safety design characteristics, which are remarkably similar irrespective of mode type preference. The study concludes that subjective safety is a novel starting point for urban transport designs.

满足活跃模式用户需求的交通基础设施是可持续和公正的城市交通转型的基本要素。安全是影响骑自行车者行为的主要因素，了解交通参与者如何看待安全可以支持城市设计，从而吸引更多活跃的旅行者。本文评估了驾车者、骑自行车者和行人对安全交通基础设施的偏好。它依赖于非政府组织 FixMyBerlin 与德国报纸Berliner Tagesspiegel合作收集的数据. 21,401 名参与者共评估了 1900 种不同的交通状况，产生了 468,379 条关于主要街道、小街和人行道等街道设计元素的意见样本。结果指出了宽阔的自行车道以及将骑自行车者与机动车辆和行人交通分开的重要性。取消自行车道旁边的停车位对于提高安全意识也非常重要。这些数据提供了对城市安全设计特征关键要素的详细洞察，无论模式类型偏好如何，这些特征都非常相似。该研究得出结论，主观安全是城市交通设计的一个新起点。
