Abstract：
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.
摘要：
自行车街是一条混合交通的街道，机动车被迫使其速度适应自行车交通，例如，鼓励在街道中间使用居中的自行车道骑自行车。骑车人的客观安全性随着较低的车辆速度和较少的机动车辆而增加。尽管如此,在混合交通的街道上，骑自行车的人对他们的安全感往往会降低。主观不安全和风险构成了增加循环的主要障碍。这项研究调查了自行车街道微环境的设计如何提高混合交通中骑车人的感知安全性。进行了一项准实验调查，其中371名参与者对他们在照片操纵的自行车街道上的感知安全性进行了评估。52%的参与者是男性，平均年龄为43（20-77）岁，76%的人报告说他们每周有4-5天或更长时间的周期。重点是评估微环境因素，例如居中自行车道的不同设计，道路标记,标志,交通量,和停放的汽车。结论是，微环境对骑车人的感知安全性具有重要影响。通过相当简单的设计努力可以实现主观安全性的重要增益。当街道中央有明确划定的红色自行车道以及骑自行车者的道路标记时，许多参与者感到安全。最强的效果，然而,来自减少交通量。大多数参与者在交通量减少的微环境中感到安全，包括那些没有进行设计更改的人。还发现了不同组的骑自行车者之间的重要差异。
