description: Decades of vehicle dominated mobility policy has created streetscapes that endanger pedestrians. Pedestrian-vehicle collisions disproportionately impact older adults (aged 65+), with fatality rates three times higher than younger age groups. Similarly, factors such as episodic or permanent disability, and gender increase overall exposure times and collision risks. Despite this awareness, physical infrastructure and transportation policies inadequately address environmental hazards that create mobility barriers for vulnerable populations. This thesis identifies critical gaps in mobility policy, data, and street design, highlighting the inadequacies of current civic infrastructure in serving diverse populations and understanding pedestrian challenges. While policy directives often target the demographic majority, they overlook those facing the greatest risks. To address this policy mismatch, this study conducts a segment and thematic analysis of crowdsourced data to identify common barriers to pedestrian safety and accessibility. Over 3000 reports (missing amenity, incident, hazard and concerns) from WalkRollMap.org, collected between May 2021 and December 2023, were analyzed to explore demographic variability in barriers to pedestrian mobility. The segment analysis revealed common barriers, such as the need for adequate pedestrian infrastructure, as indicated by missing amenity reports. Incident reports suggested that vehicle-centric street designs create conditions where pedestrians are not visible to moving vehicles. Hazard and concern reports highlighted issues with inadequate crosswalks, poor sidewalk conditions, and motorist entitlement. The thematic analysis provided clearer demographic insights. Women and non-binary respondents identified safety concerns due to inconsiderate street users. Youth reported unsafe conditions from aggressive motorists in school zones. Older adults emphasized difficulties with unpredictable cyclist speeds and volumes. Disabled individuals expressed fear and caution regarding steep or obstructed sidewalks. The study's findings underscore the need for inclusive data collection and policy formulation processes. Achieving inclusively designed cities requires engaging directly with vulnerable populations to understand their diverse needs. By bridging this gap, cities can better support the health and active mobility of all residents.
