This study establishes the causal effect of winter streets’ design on people’s psychological health, specifically, restoration from stress and mental fatigue. A lab experiment was conducted to identify the effect of vegetation and brightness in winter scenarios on people’s mental restoration. Sixty-three participants were randomly assigned to three different treatments (vegetation, brightness, and control). Participants in the vegetation treatment recovered from mental fatigue quicker than those in the brightness and control groups. The findings resulting from this lab experiment inform planning principles and policies for restorative urban design by providing evidence showing how urban streets can improve people’s mental health in winter cities.

本研究确定了冬季街道设计对人们心理健康的因果影响，特别是压力和精神疲劳的恢复。进行了一项实验室实验，以确定冬季场景中植被和亮度对人们心理恢复的影响。63 名参与者被随机分配到三种不同的处理（植被、亮度和控制）。植被治疗的参与者比亮度组和对照组的参与者从精神疲劳中恢复得更快。该实验室实验的结果通过提供证据表明城市街道如何改善冬季城市中人们的心理健康，从而为恢复性城市设计的规划原则和政策提供信息。
