摘　　要：安全感对心理健康、步行行为和出行决策至关重要,夜间安全已成为城市夜间活力和街道可步行性的核心需求。通过叙述性偏好法调查夜间步行者的环境选择偏好,构建离散选择模型,量化分析影响安全感的关键街道环境要素及其机制。研究发现,治安岗亭、沿街界面类型、人行道宽度、照明亮度、人车分隔设施、车流量大小和街道尺度显著影响夜间步行安全感。以苏州市独墅湖科教创新区为案例地,基于安全感效用指标对街道现状进行评价并提出优化策略,以期为改善街道步行环境提供一种创新的行为视角。Perception of safety is crucial for mental health,walking behavior,and travel decision-making,and nighttime safety has become a core requirement for urban vibrancy and street walkability.This study employed the stated preference method to investigate the environmental preferences of nighttime pedestrians,constructing a discrete choice model to quantify the key street environment factors influencing perceived safety and their underlying mechanisms.The findings reveal that key factors significantly impacting nighttime walking safety include security kiosks,street interface types,sidewalk width,lighting brightness,pedestrian-vehicle separation facilities,traffic volume,and street scale.Using the Suzhou Dushu Lake Science and Education Innovation Zone as a case study,the authors evaluate the current conditions of street segments based on a safety perception utility index and propose targeted optimization strategies.This research offers an innovative behavioral perspective for improving the pedestrian environment.
