A bicycle street is a mixed traffic street where motor vehicles are forced to adapt their speed to bicycle traffic, for example by encouraging cycling in the middle of the street using centered bicycle lanes. The objective safety of cyclists increases with lower vehicle speeds and fewer motor vehicles. Despite this, cyclists' perception of their safety is often reduced in mixed traffic streets. Subjective unsafety and risk constitute a major barrier to increased cycling. This study investigates how the design of the micro-environment of bicycle streets can improve cyclists' perceived safety in mixed traffic. A quasi-experimental survey in which 371 participants rated their perceived safety in photo-manipulated bicycle streets was conducted. 52% of the participants were male, the mean age was 43 (20-77) years, and 76% reported that they cycle 4-5 days a week or more. The focus was on evaluating micro-environmental factors such as different designs of centered bicycle lanes, road markings, signs, traffic volume, and parked cars. It is concluded that the micro-environment has important effects on the perceived safety of cyclists. Important gains in subjective safety can be achieved with fairly simple design efforts. Many participants felt safe when there were clearly demarcated red-colored bicycle lanes in the center of the street accompanied by road markings for cyclists. The strongest effect, however, comes from reducing traffic volume. Most participants felt safe in micro-environments in which the traffic volume had been reduced, including those where no design changes had been made. Important differences between different groups of cyclists were also found.
自行车道是一种混合交通道路，机动车辆被迫在这种道路上降低速度以适应自行车交通，例如通过在道路中间使用中心式自行车道来鼓励骑车。随着车辆速度降低和机动车数量减少，自行车骑行者的安全性客观上会提高。尽管如此，在混合交通道路上，自行车骑行者对自身安全的感知往往会降低。主观上的不安全和风险是增加骑行的主要障碍。本研究旨在探讨自行车道微观环境的设计如何能提高混合交通中自行车骑行者的感知安全性。研究采用准实验调查方法，让 371 名参与者对经过照片处理的自行车道的感知安全性进行评分。参与者中 52%为男性，平均年龄为 43 岁（20-77 岁），76%的参与者报告每周骑车 4-5 天或以上。研究重点评估了微观环境因素，如中心式自行车道的不同设计、道路标线、标志、交通量和停放的汽车。研究结果表明，微观环境对自行车骑行者的感知安全性有重要影响。通过相当简单的设计努力，可以显著提高主观安全性。当街道中间有明确划分的红色自行车道，并配有自行车道标线时，许多参与者会感到安全。然而，最有效的方法是降低交通量。当交通量减少时，包括没有进行设计改变的情况下，大多数参与者都感到安全。此外，还发现了不同自行车骑行者群体之间的重要差异。
