A Mental Health-Informed AHP–FCE Assessment of Living-Street Quality for Sustainable Micro-Renewal in Aging Communities: Evidence from Xuesong Road, Wuhan, China

Neighborhood living streets are key everyday public spaces in mixed residential–commercial districts and are an important setting for residents’ mental well-being. Yet many neighborhood evaluations still rely on coarse spatial indicators and provide limited guidance for fine-grained renewal. This study develops a comprehensive, mental-health-relevant, perception-based framework for assessing living-street quality and applies it to Xuesong Road, an aging community street in Wuhan. Five perception dimensions—walkability, safety, comfort, sociability, and pleasure—are operationalized into 18 micro-spatial indicators. Indicator weights are derived from expert judgments using the Analytic Hierarchy Process, and 178 residents’ Likert-scale ratings are synthesized using Fuzzy Comprehensive Evaluation to obtain dimension-level and composite scores. On a five-point scale, the overall score of 3.08 indicates a mid-range level of perceived street quality in relation to mental health. Sociability performs best, followed by walkability, pleasure, and comfort, while safety is the weakest dimension, mainly due to conflicts with non-motorized traffic and inadequate nighttime lighting. The proposed AHP–FCE framework links micro-scale street attributes to perception-based outcomes and provides actionable evidence to inform micro-renewal, with safety-oriented interventions being prioritized to support social sustainability and age-friendly communities.
